The Omron E3S-R67 utilizes retro-reflective sensing and an infrared LED (850 nm) to detect transparent and opaque objects with a sensing range of 300 mm. It supports standard targets such as LCD glass boards and cylindrical glass objects, with NPN output and a fast 1 ms response time. Powered by a 10 to 30 VDC supply, the sensor integrates easily using its robust M12 connector and features an intuitive Light-ON/Dark-ON selector switch along with a two-turn endless sensitivity adjuster for fine-tuned detection.

Designed for industrial environments, the E3S-R67 boasts IP67-rated protection, making it highly resistant to dust, water, vibration, and shock. The body is constructed using polybutylene terephthalate, modified polyallylate, and stainless steel (SUS304), ensuring strength and durability. With its ability to reliably detect low-contrast, transparent targets under ambient lighting up to 10,000 lx, this sensor is a trusted choice for packaging, inspection, and glass handling industries.
