Product Description

The SICK 1066885 (KTM-MB8A191P) is a high-performance contrast sensor from the KTM Core series, specifically designed to provide reliable mark detection in space-restricted environments. This sensor utilizes a white LED light source and a round, small light spot to differentiate between subtle gray tones and contrast levels on various surfaces. With a fixed sensing distance of 11 mm and a high switching frequency of up to 10 kHz, it ensures precise positioning and high machine throughput even in high-speed production lines.

Housed in a compact 12 mm x 31.5 mm x 21 mm plastic casing, it is ideal for integration into small machinery. The KTM Core series stands out for its simplicity; it features a manual potentiometer for quick and intuitive adjustment, allowing operators to set the switching threshold effortlessly without complex programming. Its robust IP67-rated design ensures durability in industrial environments, while the dual PNP/NPN switching output provides universal compatibility with various control systems. This sensor is the go-to solution for cost-effective yet highly accurate contrast detection in the packaging and printing industries.

Key Performance Features

High Switching Frequency: Operates at up to 10 kHz for rapid processing in high-speed applications.
Compact Housing: Small dimensions (12 mm x 31.5 mm x 21 mm) allow for mounting in very tight spaces.
White LED Light Source: Reliable detection of various color contrasts and grayscale differences.
Simple Setup: Intuitive adjustment via a manual potentiometer for fast commissioning.
Dual Output: Integrated PNP and NPN switching outputs for flexible integration.
Rugged Construction: IP67 enclosure rating provides protection against dust and water ingress.

Ideal Applications

Packaging Industry: Accurate detection of print marks on continuous materials for cutting and folding.
Labeling Machines: Precise alignment of labels on bottles, tubes, and containers.
Printing Processes: Monitoring of registration marks and web positioning.
Food and Beverage: Detecting contrast differences on packaging foils and glossy materials.
Small Machinery: General-purpose contrast sensing where space is at a premium.
