Before procurement teams confirm E3S-AR66, they typically review Omron Photoelectric Sensor, E3Z D61 2M and Omron Sensors to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron E3S-AR66 Photoelectric Sensor
The Omron E3S-AR66 Photoelectric Sensor is a medium sensor with built-in amplifier featuring retro-reflective with M.S.R. function, vertical design, and a 2 m sensing distance (using E39-R1 reflector). Operating on a 10β30 VDC power supply, it provides reliable NPN output through an M12 connector and belongs to the Omron automation range under the Omron Photoelectric Sensors category and the Omron E3S Series. Equipped with a red LED (660 nm) light source, it ensures fast 0.5 ms response time, Light-ON/Dark-ON selectable mode, and IP67 protection with a 30 mA current consumption and 100 mA load current capacity for dependable industrial performance.
