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.
