It detects opaque objects as small as 2 mm by 0.8 mm, making it a fit for edge detection, label sensing, or part-presence checks in tight spaces — the U-slot body lets you mount it directly around a moving web or belt. Response time is 0.17 ms, and the switching frequency hits 3 kHz — fast enough to catch parts on a moderate-speed conveyor or rotary indexer without missing edges. The infrared LED emitter is invisible, so it won't trigger false readings from ambient visible light. ## NPN dark-on output, 5-24V DC supply Output is NPN open-collector, dark-on switching mode — the transistor turns on when the light path is blocked. Maximum load current is 100 mA, enough to drive a small PLC input or a relay coil directly. Supply voltage range is 5-24V DC, so it works on standard 24V control systems or lower-voltage logic rails. The prewired 2 m cable (bare wire termination) saves wiring time in panel builds — no separate connector to source. The indicator LED on the body gives a quick visual on output state during commissioning or fault-finding. ## IP64, PBT body, current production CE and RU (Russia) approvals cover European and Eurasian markets. Operating temperature range is -13 °F to 131 °F.","metaTitle":"Omron EE-SX770 Photoelectric Sensor, Through-Beam, 5 mm, NPN","metaDescription":"Omron EE-SX770 through-beam photoelectric sensor, 5 mm sensing distance, NPN output, 5-24V DC, 0.17 ms response, IP64.
