The Omron E3Z-R81K 2M is a retroreflective photoelectric sensor from the E3Z series, designed for object detection in automated lines — packaging conveyors, material handling, and assembly stations where a clear path between the sensor and its reflector is available.
Output type and sensing distance
The E3Z-R81K 2M is a retroreflective sensor — it emits a modulated light beam and detects objects when the beam is broken between the sensor and its reflector. A reflector is required for operation; the sensor does not include one in the base package. The reflector model and mounting bracket are specified separately based on the application range needed.
