The Autonics has engineered the BS5-Y1M to deliver high-speed detection in compact applications. This Groove-Depth 9 mm Photomicro Sensor operates on a through-beam sensing principle with a 5 mm sensing range, precisely identifying opaque targets ≥Ø0.8mm × 2mm. Built for rapid operations, it offers response times of 20µs (Light ON) and 100µs (Dark ON), supported by a stable infrared LED (940 nm) light source. The BS5-Y1M is designed for versatility, with selectable output modes and NPN open collector output for seamless integration into industrial control systems. Power-efficient and reliable, it runs on 5–24VDC ±10% and includes advanced circuit protections like reverse polarity and short-circuit protection. Its rugged IP50-rated body ensures consistent operation in tough factory environments.
It delivers an impressive response frequency of 2 kHz with ultra-fast response times: 20µs for Light ON and 100µs for Dark ON modes. Powered by a 940 nm infrared LED, the sensor supports both operation modes via a selectable control wire, offering versatility across applications. The NPN open collector output enables easy PLC integration, while the 5–24VDC ±10% power input with only 30mA max current consumption ensures energy efficiency and device protection.
The BS5-Y1M is designed with robust electrical protections including reverse polarity protection and short-circuit output protection. Built from high-durability PBT and PC materials, it meets the IP50 protection standard and operates flawlessly in harsh industrial environments ranging from -20°C to +55°C, withstanding vibration and shock conditions common in automated machinery. These features make it ideal for engineers seeking consistent, long-term performance.
