L-shaped fork sensors use through-beam photoelectric technology to detect objects passing through the slot. The rugged one-piece housing keeps the emitter and receiver in alignment. These infrared light models are available in sensing distances up to 160mm, with quick-disconnect termination. Light / Dark selectable operation allows easy setup.
L-frame fork sensors (slot sensors) are L shaped through-beam object detecting sensors that have the transmitter and receiver built into the opposing "fork" arms of the sensor housing.
