The Autonics BYD3M-TDT-P Compact Photoelectric Sensor features a through-beam sensing type capable of detecting opaque objects as small as Γ6mm over a stable 3m range. Powered by an infrared LED, it operates in Dark ON mode for reliable performance in varied lighting conditions, with an ultra-fast 1ms response time that ensures timely detection in high-speed automation processes.
It runs on a 12β24VDC power supply (Β±10% tolerance) and consumes a maximum of 30mA per emitter/receiver, making it energy-efficient for continuous operation. The PNP open collector output offers easy integration with PLCs and control devices. Built with a rugged PC and SPCC housing, the sensor has an IP64 protection rating, ensuring resistance against dust and light water exposure. The Γ3.5mm, 2m cable provides a secure and flexible connection for varied installation layouts. Its immunity to ambient light up to 11,000lx (sunlight) and operating temperature range of -20Β°C to 65Β°C make it dependable across a wide range of industrial environments.
