4 General Information Inductive multiple and single limit switches are used for positioning and control in all areas of mechanical and systems engineering. They are ideal for performing automation tasks in machines used in the wood, textile and plastics industries, as well as for area monitoring in robot installations. Thanks to their non-contact, wear-free principle of operation, inductive multiple and single limit switches are unaffected by strong vibrations or heavy soiling and have an above-average mechanical service life even under aggressive ambient conditions. Five different inductive multiple limit switch designs with 8 mm, mm or 6 mm proximity switch spacing are available to cover a wide range of applications; these can be equipped in turn with a large number of different inductive switching elements. In addition to these multiple limit switches, the product range also includes single limit switches according to DIN 69 and the particularly compact ESN design. This flexibility ensures that a solution can be provided for practically any application. Interchangeability with mechanical multiple and single limit switches means that machines can be converted without any problems. The switches can therefore be retrofitted on existing machine installations to take full advantage of the benefits of non-contact switches. The multiple limit switches can also be equipped with a mixed complement of mechanical safety switching elements and inductive switching elements for safety-relevant end of travel limit switching, EMERGENCY STOP functions or other safety-critical applications. In this way, the advantages of non-contact switching can be combined with positively driven NC contacts.

26 Additional Products Precision multiple limit switches for high switching point accuracy and safety EUCHNER offers precision multiple limit switches as an alternative to inductive multiple limit switches. There are four functionally different plunger ends available for various areas of application with 8, or 6 mm plunger spacing respectively. The precision multiple limit switches can be assembled with snap and safety switching elements, or also in combination with inductive switching elements. A type series with an external membrane which is designed to resist the effect of resinous cooling lubricants is also available. This version prevents the plungers from sticking. Technical data Housing material anodized aluminum Degree of protection IP67 Actuator chisel, roller, ball and dome plungers Switching point accuracy, max. ± 0.00 mm Approach speed, max. 0 m/min Mechanical life up to 0 x 0 6 mech.operations Trip rails / trip dogs U-trip rails enable the adjustment of the trip dogs from the switch side. The trip dogs can be installed and adjusted quickly and easily in any location. U-trip dogs are designed for use in U-trip rails. They have an expansion plate clamp and enable precise adjustment, even when the limit switch is activated. G-trip rails enable the adjustment of trip dogs from the side opposite the switch. They are made of steel and are protected from corrosion by a special surface treatment. Trip rails can be ordered preassembled or as a component for self-assembly. G-trip dogs are designed for use in G-trip rails. The trip dogs are clamped in the trip rail by a hexagon socket screw with spring washer. This washer locks the trip dog in place even when the trip rail is in vertical position, and allows precise adjustment. 6 Subject to technical modifications; no responsibility is accepted for the accuracy of this information.

27 Appendix Terms and explanations Rated operating distance s n The rated operating distance is a general variable used for measurement of operating distances. It does not take into account either the production tolerances or changes caused by external effects such as voltage and temperature. Assured operating distance s a The assured operating distance is the operating distance at which correct operation of the inductive switching element is guaranteed within the permissible operating conditions (temperature and voltage). The actuation distance lies between 0 and 8 % of the rated operating distance s n., s n Total tolerance range s n 0,8 s n Test plate, s n Manufacturing tolerance 0,9 s n Sensing face Inductive switching element Differential travel H The differential travel is the difference in distance terms between the ON point as the test plate approaches and the OFF point as it moves away from the sensing face of the inductive switching element. Radial approach Axial approach Differential travel Opening curve Closing curve Repeat accuracy R The repeat accuracy is the accuracy with which the real operating distance s r is reproduced r for two switching actions in succession within 8 hours at an operating temperature of ±5 C and an operating voltage of UB ±5 %. Operating voltage U B The operating voltage defines the voltage range in which the inductive switching element functions reliably. The specified values represent limits without any tolerances. The values can be obtained by referring to the technical data for the switching element. In the case of two-wire switching elements, this is applicable only in series connection with the load. Rated operating current I e The rated operating current is the nominal current which can load the inductive switching element in continuous operation. Inrush current I K The inrush current is the maximum current which can flow in an AC--wire switching element for a particular period at the moment it is switched on. The details in the technical data are valid for 0 ms. Voltage drop U d The voltage drop is measured across the active output of the inductive switching element when the output is in the throughconnected condition and when the rated operating current I e flows. Off-state current I r The off-state current is the current which flows in the load circuit of an inductive switching element in the non-conducting condition. In practical terms, this current has to be taken into account only for twowire switching elements. Switching frequency f The switching frequency is the maximum possible number of switching operations per second. This is determined according to IEC and is based on a markspace ratio of :. The switching frequency is a switch-specific variable and can be obtained by referring to the technical data for the switching element. Operating current, minimum I m The minimum operating current is the minimum current required for the functioning of a -wire switching element in active energized condition. Ambient temperature T The ambient temperature is the temperature range in which the reliable operation of the inductive switching element is guaranteed. This range is between - 5 and + 70 C. Temperature drift s The temperature drift defines the offset in the switching point in µm/k on a change in the ambient temperature from -5 to +70 C under otherwise constant measurement conditions. Subject to technical modifications; no responsibility is accepted for the accuracy of this information. 7

28 Switching functions NO function The NO function means that the load current flows when the sensing face of the inductive switching element is activated and that no current flows when the sensing face is undamped. DC NO, PNP NC function The NC function means that the load current does not flow when the sensing face of the inductive switching element is activated and that current flows when the sensing face is undamped. DC NC, PNP NO + NC function The NO + NC function incorporates both an NO function and an NC function. Associated circuit diagrams and wiring diagrams are given in the technical data. DC NO + NC, PNP Suppressor circuits The inductive switching elements are largely protected against external interference by use of various circuit techniques (suppressor circuits). For utilization category DC- the output must be protected with a free-wheeling diode for inductive loads. Short-circuit and overload protection The inductive switching elements are designed so that short circuits cannot damage the outputs. Pulsed shortcircuit protection is used. This means that the output transistor is switched off and on again in quick succession in the event of overloading or a short-circuit. In this way, it is possible to establish whether the fault is still present or has been rectified. Transient protection EUCHNER proximity switches are protected against interference caused by the occurrence of inductive voltage peaks in accordance with IEC 80-. The respective values are specified in the technical data. Testing is performed in accordance with the stipulations in DIN VDE 0660, Part 08 and IEC Wire break safety EUCHNER proximity switches with wire break protection are designed so that the switch does not output spurious signals in the event of a break in any connecting wire. Reverse polarity protection Protection against reverse polarization of the operating voltage. Customized versions Inductive switching elements according to NAMUR These switching elements fulfill the specification IEC and IEC 6 9. The current consumption at U B = 8. V is greater than.5 ma when the oscillator face is not activated and less than.0 ma when the oscillator face is activated. The current consumption characteristic is linear during the transition from the inactivated to the activated state of the oscillator face, i.e. these switches do not have a snap action. DC--wire switching elements Two-wire switching elements can be used in principle instead of mechanical switches. Their low off-state current makes them especially suitable for use in conjunction with programmable logic controllers. Compared with three-wire switching elements they have the advantage of requiring less wiring. Increased operating distance For designs with mm proximity switch spacing, switching elements with increased operating distance are available on request (s n = 5 mm). Due to their technical characteristics, these switching elements can be used both with a pulsed operating voltage and an operating voltage that is not pulsed. 8 Subject to technical modifications; no responsibility is accepted for the accuracy of this information.
