Presence and Position Sensors  from Prime Controls Co.   Balluff Inc.
Balluff Inc., founded in 1921, is one of the world's leading sensor manufacturers. Balluff was one of the companies who invested in the development of the proximity switch and an original patent holder of that technology. They now offer a wide range of sensors using various technologies. The most common Balluff proximity sensors are in stock at Prime Controls Company for immediate delivery.
