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. As a current-production Omron part, the E3T-ST12 DC12-24 can be quoted to order with typical lead times. Send an RFQ with your quantity and target delivery date; we will confirm availability and pricing against your BOM line.","metaTitle":"OMRON E3T-ST12 DC12-24 Photoelectric Sensor, 1m sensing, 1 m","metaDescription":"OMRON E3T-ST12 DC12-24 compact through-beam photoelectric sensor with 1 m sensing distance, 1 ms max response time, open-collector output, pre-wired 2m.
