Sensors

The NSS is designed to allow easy field adjustments. Two magnets are secured to the end of the lift shaft to ensure a positive response once it passes near the position sensor. To adjust the position sensors simply position the lift shaft in the correct position, loosen the locking screw, and then slide the movable sensor to the desired location until the sensor indicates a response. The NSS is supplied with three slots in the stem cover, and two position sensors. Additional sensors can be added or moved to any of the three slots. It is also possible to add multiple sensors to the same slot.

The sensor system is supplied with two PNP or NPN (normally open) switches. For additional switches or to order a normally closed switch, contact Nook Application Engineers.
