Fork Sensors

Fork sensors (also called slot sensors) use through-beam photoelectric technology to detect objects passing through the slot. The rugged one-piece housing, available in U- and L-frame styles, keeps the emitter and receiver in alignment, and includes a convenient, single-cable connection.

Fork Sensors

Fork sensors, also called slot sensors, are U- and L-shaped through-beam object detecting sensors that have the transmitter and receiver built into the opposing "fork" arms of the sensor housing. They offer several advantages over standard through-beam sensors in certain applications:

Identical mechanical and optical axis
Operational reliability and repeatability
Transmitter / receiver built into the same housing
Models available for clear object and liquid detection
Ease of installation - one connection point
