Omron E3Z-LS81-UL 2M : Distance-Setting Photoelectric Sensor
The Omron E3Z-LS81-UL 2M Photoelectric Sensor is a compact, square-type sensor engineered for precise distance detection in industrial automation. With a sensing range of 20 to 200 mm, it supports adjusted detection of white and black targets (40–200 mm for white paper, 40–160 mm for black paper). A red LED light source (670 nm) ensures accurate and consistent performance, with minimal differential error (<10%).
This sensor features a PNP open-collector output (max 100 mA at 26.4 VDC) and Light-ON/Dark-ON mode selection for application flexibility. A 5-turn endless sensitivity adjustment dial allows fine calibration. Designed for fast-paced environments, it offers a 1 ms response time and includes short-circuit and reverse polarity protection.
Constructed from PBT and denatured polyarylate, the sensor is IP67-rated for water and dust resistance and withstands temperatures from -25°C to 55°C. Dual LED indicators (green for stability, orange for operation) simplify monitoring. The E3Z-LS81-UL is a dependable solution for accurate, close-range sensing in challenging environments.
Our engineers actively inputted all the required details of this item in accordance with the datasheet. Nevertheless, it’s imperative to recognize that errors may arise during this process.
