Our magnetic field sensors for T-slots detect the piston position without contact through the cylinder wall. Features: can be mounted directly in the slot, firm hold, can be installed flush for space-critical applications, can be used for cylinders and grippers with strong or weak magnets, bright LEDs. Extremely short designs as well as sensors with metal housing or magnetic field-sensitive electronics available. Magnetic field sensor, connection type 01=cable with connector, switching output 01=PNP, switching function 01=normally open (NO), primary housing material=PA, protection class=IP67, fastening=can be inserted from above in T-slot, application=pneumatic cylinder with T-slot. Dimensions see sketch in product view.
