Output is NPN open-collector, active when the beam is uninterrupted (Light-ON). Supply is fixed at 5 V DC. The housing mounts via M3 screws to a chassis or bracket — no DIN rail clip, so plan for a drilled panel or custom bracket. Rated for -25°C to 55°C ambient. That covers most indoor industrial cabinets and light-duty automation, but not freezer or outdoor direct-sun applications. The through-beam design is immune to ambient light interference in the slot, but the housing is not sealed — no IP rating listed, so keep it away from washdown zones or condensation-prone areas.","metaTitle":"Omron EE-SX871 Through-Beam Sensor, NPN Light-ON, 5 mm, 5 V","metaDescription":"Omron EE-SX871 through-beam photomicrosensor, NPN open-collector Light-ON output, 5 mm sensing distance, 5 V supply, chassis mount with M3 screw.

The output sinks to ground when the light beam is uninterrupted. No internal pull-up resistor — you must add one externally to the logic supply."},{"question":"Is EE-SX871 active or obsolete?","answer":"Active. The lifecycle status is current production — no discontinuation notice. It remains a standard catalog item for Omron."},{"question":"What is the supply voltage for EE-SX871?","answer":"5 V DC, fixed. Not a wide-range supply — must match the control logic rail. Do not exceed 5 V without checking the absolute maximum ratings in the datasheet."},{"question":"Does EE-SX871 require an external pull-up resistor?","answer":"Yes. The NPN open-collector output has no internal pull-up. Connect a resistor (typically 1 kΩ to 10 kΩ) from the output pin to your logic supply to get a valid high-level when the beam is blocked."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/omron/EE-SX871","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/omron/EE-SX871 when reusing this data.
