The Autonics BS5-K1M Groove-Depth 9 mm Photomicro Sensors use a through-beam sensing type with a fixed 5 mm sensing distance, capable of detecting opaque objects as small as Γ0.8 mm Γ 2 mm. A hysteresis of β€0.05 mm ensures stable, repeatable accuracy in fast-moving industrial applications like assembly verification and thread detection.
Powered by 5β24 VDC Β±10% and drawing just 30 mA, the BS5-K1M offers rapid 20 ΞΌs Light ON and 100 ΞΌs Dark ON response times, with a 2 kHz operating frequency for high-speed automation. A 940 nm infrared LED enables reliable performance even under ambient light up to 1,000 lx. The NPN open collector output integrates easily with PLCs, supported by built-in reverse polarity and short-circuit protection for long-term electrical safety.
With a rugged PBT + PC housing rated IP50, the Autonics BS5-K1M Groove-Depth 9 mm Photomicro Sensors withstand vibration up to 196 m/sΒ² and shocks up to 15,000 m/sΒ². Operating in temperatures from -20Β°C to 55Β°C, they are built for continuous use in harsh conditions, backed by Autonics Sensors & Controllers quality assurance.
The Autonics BS5-K1M Groove-Depth 9 mm Photomicro Sensors are widely applied in assembly line part detection, thread presence monitoring, and precision jig automation. Their high-speed switching supports conveyor sorting, label verification, and quality inspection without process delays. Maintenance engineers value the cable-type connection for secure, stable installation, while OEMs trust its accuracy and durability for high-cycle industrial production.
