Information About E3Z-LS81
The E3Z-LS81 is part of Omron’s E3Z series of photoelectric sensors, known for their compact housing and stable detection performance. It uses a red LED light source and a five-turn endless adjuster to fine-tune sensing distance within the 20 mm to 200 mm range. The unit includes a built-in amplifier, eliminating the need for an external control module and simplifying installation. Designed with an IP67-rated enclosure and a 2-meter pre-wired cable, it is suitable for use in industrial environments where resistance to dust and moisture is required.
