Product Description

The SICK KT8L-N3656 is a premium laser-based contrast sensor designed for demanding detection tasks where extremely small marks or precise positioning are required. Utilizing a highly focused red laser light spot of just 0.3 mm, this sensor can detect minute contrast differences even at a generous 150 mm sensing distance. Its robust die-cast zinc housing and IP67 rating ensure reliable performance in harsh industrial environments.

Equipped with a high-speed switching frequency of 17 kHz and a rapid response time of 30 µs, the KT8L-N3656 is optimized for high-speed automated processes. The device offers versatile setup options through static 2-point teach-in or dynamic teach-in modes, allowing for quick adaptation to various materials and backgrounds. With both NPN digital switching and a 0.3 mA to 20 mA analog output, it provides comprehensive data for both simple trigger events and complex process monitoring.

Key Performance Features

High-Speed Detection: 17 kHz switching frequency for high-speed production lines.
Precise Laser Spot: Small Ø 0.3 mm laser spot allows for the detection of very fine print marks.
Flexible Teach-in: Features both static 2-point and dynamic teach-in modes via a button.
Dual Output: Simultaneous NPN digital output and analog output for integrated process control.
Durability: Rugged die-cast zinc housing with an IP67 enclosure rating.
Long Range: Extended 150 mm sensing distance offers more mounting flexibility than standard contrast sensors.

Ideal Applications

Printing Industry: Detecting tiny register marks or small control marks on high-speed web presses.
Packaging Machinery: Precise positioning of labels or tubes where space is limited and accuracy is critical.
Electronics Assembly: Detection of small components or contrast marks on PCBs.
Quality Control: Monitoring material consistency via the analog output signal.
