E3T-ST12M(2M) Photoelectric Sensor, Through-Beam

The E3T-ST12M(2M) is a through-beam photoelectric sensor from the E3T series. It uses a separate emitter and receiver; the output switches when the beam is broken — a reliable method for presence detection on conveyors, machine loading stations, and part-present checks where the environment is clean enough that beam occlusion is the signal. No pulse-modulated or background-suppression variants here — this is a straight through-beam, so factor in emitter-to-receiver alignment and keep the optical path clear. If that fits your application, tell me the quantity and I'll get a lead time. Sourced to order against an RFQ.
