Product Overview
The Omron E3Z-T81 is a compact through-beam photoelectric sensor from the E3Z series, designed for reliable object detection in industrial automation applications. This sensor features a through-beam configuration with separate emitter and receiver units, providing a sensing distance of up to 5 meters for long-range detection applications. The through-beam design offers the highest detection reliability among photoelectric sensor types, as the light beam travels directly from emitter to receiver without reflection, making it ideal for detecting opaque objects in dirty or dusty environments where other sensing methods may fail. The E3Z-T81 features PNP normally-open output configuration, compatible with most modern PLC input cards and safety circuits. The sensor operates on 12-24VDC supply voltage, providing flexibility in various control system configurations. The compact M18 cylindrical housing allows easy installation in tight spaces and standard mounting brackets. The sensor includes a sensitivity adjustment potentiometer, enabling fine-tuning for optimal detection performance in varying ambient light conditions or with different object surfaces. The visible red LED light source simplifies alignment during installation, allowing quick and accurate sensor positioning. The E3Z series is known for its robust construction with IP67 protection rating, ensuring reliable operation in harsh industrial environments with exposure to dust, water, and oil. Applications include conveyor systems, packaging machinery, material handling equipment, and any application requiring reliable presence detection over longer distances.

FAQ for E3Z-T81
What is included in the E3Z-T81 package?
The E3Z-T81 includes both the emitter (E3Z-T81-E) and receiver (E3Z-T81-R) units as a matched pair, each with 2m cable. Mounting brackets are sold separately.
Can E3Z-T81 detect transparent objects?
Through-beam sensors can detect some transparent objects, but detection reliability depends on transparency level. For highly transparent materials, consider a specialized transparent object sensor.
What mounting brackets are available?
The E39-L101 mounting bracket kit provides adjustable mounting for M18 sensors, allowing precise alignment of emitter and receiver units.
