Leuze RK 93/4-150 L (Order Code: 50025513)

Product Overview: The Leuze RK 93/4-150 L energetic diffuse sensor is a high-performance optical detection device belonging to the robust 93 Series, engineered for harsh industrial environments. Unlike standard plastic-housed sensors, the RK 93 series features a rugged die-cast zinc metal housing and a high-quality glass lens, providing exceptional mechanical protection and extended operational longevity in 24/7 manufacturing plants. This diffuse reflection sensor detects objects without the need for a separate reflector or receiver, triggering an immediate signal when an object passes through the detection zone.

Proprietary V-Optics Technology: The standout feature of the RK 93/4-150 L is Leuze’s proprietary V-Optics technology. By focusing the light beam in a V-shaped convergence pattern, the sensor offers significant technical advantages:

• Small Object Detection: The optimized focal point allows for precise detection of tiny mechanical components or small parts often missed by standard sensors.

• Background Interference Reduction: The V-optics pattern helps reject reflections from surfaces or objects behind the detection zone, increasing system reliability.

• Enhanced Stability: Delivers consistent performance even with varying object colors or complex surface reflectivities, preventing signal loss at short range.

Performance and Signal Integration: Equipped with an infrared LED, the sensor operates with a switching frequency of 250 Hz, making it suitable for high-speed assembly and packaging lines. The detection range spans from 5mm to 150mm for white (90% reflection) objects. While performance varies with material color, the industrial IP65-rated metal housing ensures consistent operation even in dusty environments or areas subject to water spray. With a standard PNP output and M12-4 pin connection, the RK 93/4-150 L integrates seamlessly into modern PLC control systems (Siemens, Mitsubishi, Keyence, etc.) without additional signal conditioning.
