Product Description

The SICK 1041351 (KT8L-P3756) is a high-performance contrast sensor engineered for the precise detection of extremely small print marks and objects in demanding industrial environments. As part of the KT8L family, this sensor utilizes a Class 2 red laser light source to provide a remarkably small and sharp light spot, even at extended sensing distances of up to 150 mm. This laser precision makes it an ideal solution for detecting subtle contrast differences on challenging materials or high-speed production lines.

The device features a robust die-cast zinc housing with an IP67 rating, ensuring long-term reliability against dust and water ingress. Setup is simplified through a user-friendly teach-in button, supporting both static 2-point and dynamic (min/max) teach-in modes. Performance is further enhanced by a rapid 17 kHz switching frequency and a 30 µs response time, allowing for real-time monitoring of fast-moving processes. Additionally, the inclusion of both digital PNP and analog outputs provides versatile integration options for PLC systems and process controllers, making the 1041351 a cornerstone for precision-driven automation.

Key Performance Features
