PNP output switched at 12–24 VDC, rated IP66 in a metal housing. Light-on/dark-on selectable via wire; red and green indicators show operation and stability. This unit is used condition — inspect the optics before commissioning. ## How it sits against the E3S-5B41 The E3S-5B41 is a through-beam (separate emitter/receiver) with a 5000 mm range and IP67, versus this retro-reflective unit that needs a reflector and has a shorter detection path. Electrical design is identical — both PNP, same 12–24 VDC supply, same -25 to 55 °C ambient, same L/D switching, same metal housing. Wiring and PLC input match, but the optical installation is different: you need a reflector and the sensing geometry changes. If your panel was wired for the E3S-5B41, the electrical drop-in works, but the optical setup requires rework. ## Sourcing reality This unit is used, genuine Omron. Same part, different passport — we source from verified surplus and overstock channels. Genuine is genuine; warranty coverage may vary by region. Let me be transparent: quote against your BOM line and we'll confirm availability and ship from our cross-border desk.","metaTitle":"Omron E3S-X3CB4 Retro-Reflective PNP Photoelectric Sensor","metaDescription":"Omron E3S-X3CB4 retro-reflective photoelectric switch, PNP output, 12-24 VDC, IP66 metal housing.

However the sensing method changes from through-beam (separate emitter/receiver) to retro-reflective (requires a reflector). You will need to add a reflector and adjust the mounting position; the cable and pinout can stay the same."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E3S-X3CB4","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/E3S-X3CB4 when reusing this data.
