Leuze KRTM 55/4.1121,5000 Contrast sensor
The Leuze KRTM 55/4.1121,5000 Contrast sensor (Part No. 50114074, KRTM55/4.1121,5000) from the Series 55 is a high-speed contrast sensor designed for reliable mark and color differentiation in demanding industrial applications. It features an RGB LED light source with a focused beam and a compact 1.5 × 6.5 mm rectangular light spot.The sensor provides a precise operating range of 13 mm ± 2 mm and supports static 2-point teach for convenient setup. Its PNP transistor output offers an impressive 10,000 Hz switching frequency, enabling accurate detection during high-speed production processes. The sensor operates on 10–30 V DC and includes a teach button and LED display.
Its hygienic AISI 316L stainless-steel housing, IP67/IP69K protection, and CleanProof+ECOLAB compatibility make it suitable for washdown and hygiene-sensitive environments.
Applications
-
Print mark and label detection in packaging and printing machinery.
-
Color and contrast differentiation on high-speed production lines.
-
Position and registration mark detection for accurate material processing.
- Food, beverage, and pharmaceutical machinery requiring hygienic, washdown-resistant sensing.
Technical Precautions
- Maintain the recommended 13 mm ± 2 mm operating distance and ensure the sensor is correctly aligned with the target.
- Use the static 2-point teach process to establish reliable contrast detection settings.
- Supply the sensor with 10–30 V DC while keeping residual ripple within the specified limit.
- Keep the optical surface clean and avoid exceeding the –30°C to +55°C operating temperature range.
