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 3, 4, 5 are NEMA 4) Misalignment tolerant—the non-contact actuation of the MA Series switches makes them very tolerant to misalignment of up to 10 mm (0.39 in.)

■

■

Variety of terminations—select from various cable lengths or terminal strip termination for easy installation. Cable connector available on selected models. Long life—the MA Series safety interlock switches are designed for a minimum of one million actuations

Encapsulated in the MA Series is a unique 2mm high-power industrial reed which is de-rated 2mm by a non-resetable overload protection circuit depending on switch DOOR type. On presenting SLIDING the actuator to the switch, the high intensity magnetic field from the actuator causes the contacts to close. On removing the actuatorMin 50mm 2mm (opening the door), the safety contacts open, isolating the machine. Switch Switch
