The Autonics BJ7M-TDT-P delivers powerful object detection using a through-beam sensing method with a long sensing distance of 7 meters. Built to detect opaque materials as small as Γ8mm, this Compact High Performance Photo Sensor utilizes a 650nm red LED light source that enhances beam alignment and improves detection clarity. With a fast 1ms response time, itβs optimized for fast-moving automation lines and high-speed conveyors.
Engineered for stable operation, the BJ7M-TDT-P Photoelectric Sensor runs on a 12β24VDC input range and consumes only 20mA (split between emitter and receiver), making it energy-efficient. The PNP open collector output allows easy interfacing with industrial PLCs. Its Light ON/Dark ON switch provides logic flexibility, while the sensitivity adjuster helps tailor performance based on object surface or distance. Housed in a durable mix of polycarbonate, ABS, and stainless steel, it is rated IP65 for resistance to dust and water spray. The sensor includes a 2-meter cable and is supplied with a full mounting kit including brackets, bolts, and nuts for fast deployment.
