Magnetically Actuated Safety Interlock Switches Large selection choose from a large selection of contact configurations housed in plastic to satisfy most application requirements NEMA 6 enclosure enables the MA Series switches to satisfy most application requirements (MA,, 5 are NEMA ) Misalignment tolerant the non-contact actuation of the switches makes them very tolerant to misalignment of up to 0 mm (0.9 in.) Variety of terminations select various cable lengths or terminal strip termination for easy installation. Cable connector on selected models. Long life the MA Series is designed for a minimum of one million actuations A Rapid Delivery Product: Select models are available for shipment today or within to 5 days Specifications C US Conforms to EN088, EN9, EN600- UL and C-UL listed Electrical All Models Unless Indicated Safety Contacts: AC models MA- thru 5, 0,,, 6 N/C MA-, 6, N/C DC models MA-,,, 6 N/C MA-, 5, 6, 0, N/C Safety Contact Operating Distance: Make 7- mm (-0.7in.); Break -5 mm (0.7-0.98 in.)

Basic Body Styles MA-, MA-, MA-0 and MA- MA-0 and MA-6 MA- and MA- MA- and MA-5 MA-, MA- and MA-5 Operation Operating Principle Mounting Examples Contact Arrangement mm MA-, 5, 0,,,,, 6 MA-,,,,,, 6 Min 50mm Encapsulated in the MA Series is a unique high-power industrial reed which is de-rated by a non-resetable overload protection circuit depending on switch type. On presenting the actuator to the switch, the high intensity magnetic field from the actuator causes the contacts to close. On removing the actuator (opening the door), the safety contacts open, isolating the machine. Door Closed, Machine RUN Switch Actuator Door Switch Actuator Door It is advisable, where possible, to mount the switch and actuator on non-ferrous materials otherwise it may affect the operating distances. MA-,,, 6, 0 Door Open, Machine STOP, Door Covering Switch MA-,, 5, 6, mm SLIDIN DOOR No access to switch thus preventing attempts to defeat the interlock SLIDIN DOOR Wherever possible the units should be mounted so that no access can be obtained to the switch when the guard door is open, thus preventing attempts to defeat the safety system. 8
