Its key differentiator: it omits the M.S.R. (Mutual Interference Rejection) function, meaning it is the correct choice when only one sensor occupies a given optical axis and no cross-talk risk exists between adjacent units. ## Sensing distance and what M.S.R. means As a retro-reflective type, the E3Z-B82 detects objects that break a light beam between the sensor and a separate reflector. The sensing distance is set by the reflector and the optical design — typical retro-reflective sensors in this class reach several meters, but the exact distance depends on the reflector used and the target's reflectivity. The absence of M.S.R. means this sensor does not modulate its emitter to reject interference from a second nearby sensor; install it where only one unit covers the detection zone, or where beam overlap is not a concern. ## Wiring and integration The E3Z-B82 uses a standard M8 or M12 connector (verify the specific variant for your order code). Wiring follows the typical 3- or 4-wire DC configuration: brown to +24 VDC, blue to 0 V, black for NPN or PNP output depending on the model. The absence of M.S.R. simplifies wiring — no synchronization line needed between sensors.","metaTitle":"Omron E3Z-B82 Retro-Reflective Photoelectric Sensor","metaDescription":"Omron E3Z-B82 retro-reflective photoelectric sensor without M.S.R. function.

It prevents two sensors on the same optical axis from interfering with each other by modulating their emitters. The E3Z-B82 omits this function, so it is the right choice for single-sensor installations where cross-talk is not a concern. If you need to mount two sensors facing each other or in close proximity, choose a variant with M.S.R."},{"question":"Where can I buy Omron E3Z-B82 with fast shipping?","answer":"Submit an RFQ for this part to check stock and lead time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E3Z-B82","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/E3Z-B82 when reusing this data.
