2 SERIES AZ7 Compact Tamper-Resistant Movable Machine Guard Safety Interlock Switch Features & Benefits Compact design only 4" 4" 3". Ideal where space is limited. Insulation Displacement Connector (IDC) facilitates fast, easy installation. Watertight design meets IP67 washdown requirements. Eight optional key entry locations depending upon mounting arrangement. Highly tamper-resistant difficult to defeat with simple tools, tape, bent wires, etc. Reduces liability exposure. Positive-break NC contacts assure interruption of safety circuit upon actuator key removal. High-strength, stainless-steel actuator key tolerant to mechanical abuse without damage. Rugged, corrosion-resistant, high-impact glass-fibre reinforced housing tolerates the most hostile environments. Padlockable key for added security during maintenance. Designed to meet Performance Level requirements of EN ISO 349- and Safety Control Categories of EN Several styles of actuator key accommodates a wide variety of movable guards. The compact Series AZ7 is designed for use with movable machine guards/access gates which must be closed for operator safety. Their positive-opening NC contacts provide a significantly higher level of safety than conventional springdriven switches whose contacts can weld or stick shut. And their tamper-resistant design prevents bypassing with simple tools, bent wires or other readily available means. Their IP67 rating makes them ideal for interlocking safety guards in hostile environments. Operation The AZ7 electromechanical safety interlock switch consists of a rugged switch mechanism and a geometrically-unique actuating key. The key is mounted to the movable guard. Upon opening of the guard the NC contact(s) are forced to open through a direct (non-resilient) mechanical linkage with the actuating key. These positive-break NC contacts assure circuit interruption (and machine stoppage) upon removal of the actuator key. (The NO contact closes upon key removal.) When the guard is closed, the actuating key forces the NC contacts to close and the NO contacts to re-open. Note: Available with optional M2x quick-connect. SPACE-SAVING IDC CONTACTS & CONNECTOR Typical Applications The AZ7 is intended for use as a safety interlock switch on movable machine guards which, when open, expose the operator/maintenance personnel to machine hazards. Typical applications are the interlocking of protective gratings, access doors/gates, hinged covers, access panels and other movable guards. 4 is a trademark of SCHMERSAL

20 SERIES AZ 200 Pulse-Echo Based Non-Contact Safety Interlock Switch Features & Benefits Tamper resistant frequency-matched switch and actuator required for operation. Non-contact sensing for long term reliability. Dual purpose handle modern, ergonomic design no additional door handles are needed. Integral LED diagnostics indicates operating states Integral self-monitoring and door detection sensors satisfy requirements of Safety PL e to EN ISO 349-, Control Category 4 to EN *See Note on next page. One-hand emergency release hazardous area can be left quickly and safely. Switch and actuator do not protrude into door opening no risk of injury or damage from a protruding actuator. Dual PNP 250 ma safety outputs for application versatility. Designed for daisy chaining up to 3 devices, max 200 m, can be wired in series without detriment to safety performance level. The AZ 200 pulse-echo based non-contact safety interlock is designed for use with movable machine guards/access gates which must be closed for operator safety. The AZ 200 consists of an interlock switch and actuator unit with door handle and optional emergency exit handle. The actuator is always inserted into its housing, protecting the actuator and the operator against damage and injury. Utilizing pulse-echo sensor technology, the actuator and interlock can have an offset of ±5 mm and the actuator still engages the interlock. A sensor stimulates a coil in the actuator, which in turns sends a signal back to the sensor. The pulse-echo technology provides diagnostic information and detects and indicates any misalignment at an early stage. Two different actuator designs accommodate both sliding or hinged guards. The AZ 200 interlock is a dual channel design with two shortcircuit proof, safe PNP outputs, each of which can switch up to 250 ma. It features one electronic diagnostic output that can signal errors before the safety outputs are switched off, thus enabling a controlled shutdown of the machine. With continuous internal function tests, the monitoring of the safety outputs and the use of door detection sensors, up to 3 AZ 200 safety interlocks with one diagnostic output can be wired in series without detriment to the safety performance level/control category (PL e to EN ISO 349-/ Category 4 to EN 954-).

22 SERIES TZG The Series TZG is designed for use with movable machine guards/access gates which must be closed for operator safety. Their positive-opening NC contacts provide a significantly higher level of safety than conventional springdriven switches whose contacts can weld or stick shut. And their tamper-resistant design prevents bypassing with simple tools, bent wires or other readily available means. Their IP67 rating makes them ideal for interlocking safety guards in hostile environments. Operation The Series TZG electromechanical safety interlock switch consists of a rugged switch mechanism and a geometricallyunique actuating key. The key is mounted to the movable guard. Upon opening of the guard the NC contact(s) are forced to open through a direct (non-resilient) mechanical linkage with the actuating key. These positive-break NC contacts assure circuit interruption (and machine stoppage) upon removal of the actuator key. (The NO contact closes upon key removal.) When the guard is closed, the actuating key forces the NC contacts to close and the NO contact to re-open. Typical Applications The Series TZG is intended for use as a safety interlock switch on movable machine guards which, when open, expose the operator/maintenance personnel to machine hazards. Typical applications are the interlocking of protective gratings, access doors/gates, hinged covers, access panels and other movable guards. Movable Machine Guard Safety Interlock Switch Features & Benefits Highly tamper-resistant actuating mechanism difficult to defeat with simple tools, tape, bent wires, etc. Reduces liability exposure. Four optional key entry locations rotatable actuator head provides installation versatility. Positive-Break NC contacts assure circuit interruption upon actuator key removal. High key retention force (5 pounds) eliminates inadvertent opening of guard due to shock/vibration. Watertight design meets IP67 washdown requirements. High-strength, galvanized-steel actuator key tolerates mechanical abuse without damage. Rugged, corrosion-resistant housing tolerates the most hostile environments.

34 SERIES SHGV Cable-less Keyed Mechanical Safety Guard Interlock with Key Transfer System Features & Benefits Highly tamper resistant difficult to defeat with simple tools, thereby reducing liability exposure. Four optional key entry positions provides installation versatility. Three optional locking cylinder locations provides installation versatility. Corrosion resistant tolerates hostile environments. Funnel shaped entry forgiving of mechanical actuator key misalignment Low cost guard locking eliminates wiring at the guard. Designed to meet Performance Level requirements of EN ISO 349- and Safety Control Categories of EN The SHGV Series consist of a guard-mounted mechanical locking device and a 2-position key operated selector switch for control panel mounting. This unique key transfer system assures the removal of power before allowing the access control guard to be open without the need for electrical wiring at the interlocked machine guard location. Operation When the machine guard is open the transfer key (for operating the 2-position selector switch) cannot be withdrawn from the guard locking mechanism. Upon closing of the guard, the mechanical actuator key permits the transfer-key to be turned (locking the guard) and withdrawn. The transfer-key can now be removed and inserted into the 2-position selector switch, allowing it to be operated (e.g. power to be turned on) trapping the transfer key in the on position. To unlock (open) the guard, the selector switch must be turned to the off position. The transfer-key can now be withdrawn and inserted into the guard-locking mechanism for release of the mechanical actuator key and opening of the guard. The two lock barrel version allows the removal of a second transfer key when the mechanical actuator key has been released. This second transfer key prevents the removal of the power control transfer key from the keyed interlock. Thus it can be removed from the interlock by the operator to protect against the inadvertent start-up of the equipment.

Note: This system is recommended for applications in which there is no residual motion or hazard after the removal of power. For applications in which there is residual motion or the presence of a hazard immediately following the removal of power, a solenoid-locking console ( Model SVE) is recommended. Please consult factory. Typical Applications Recommended for use where wiring directly to the movable guard is cost prohibitive or subject to damage due corrosive chemicals or other harsh environmental conditions. 36 is a trademark of SCHMERSAL
