The OMRON E3T-ST12 DC12-24 is a through-beam photoelectric sensor with a 1 m sensing distance, designed for detecting opaque objects as small as 2 mm diameter. It operates on 12-24 VDC and provides an open-collector output rated at 50 mA max (26.4 VDC max supply to load). The response time is 1 ms max on both operate and reset, fast enough for high-speed packaging or material handling lines. The emitter uses a red LED at 650 nm. The pre-wired cable (2 m standard) simplifies mounting in tight spaces — the sensor body itself measures only 1.46 x 0.7 x 0.95 cm. For a BOM line, verify that the open-collector output's residual voltage (2 V max at 10-50 mA, 1 V max below 10 mA) is within your PLC input's OFF-state threshold.
