Stainless steel fork sensors

Rugged Self-Contained Through-Beams

Balluff’s leading line of fork sensors now includes IP69K-rated stainless steel, self-contained, through-beam sensors designed for the most challenging environments. These robust sensors incorporate a 316L stainless steel housing that can withstand aggressive cleaning solutions, coolants, and lubricants. The protection provided by the housing makes these sensors the ideal choice for food and beverage, packaging, metalworking, and pharmaceutical industries.

Available in 50mm and 80mm widths, these sensors feature normally open and normally closed outputs to solve most applications and allow for easy integration into control schemes. Powerful infrared light sources solve applications with mist and other airborne particulates and red light allows for easy alignment in general applications. LEDs for power and switching indication in the connector allow for easy troubleshooting and sensor status.

The “F” series of C / U slot or fork sensors are universal, self-contained, through-beam sensors. These new sensors complement Balluff’s extensive line of fork sensors that include red light, infrared, pin-point red light, and laser light sources. Versions for transparent detection, liquid detection and analog outputs for edge positioning are also included in this family of sensors.
