pd60cnk18bpt – photo contrast n/p no/nc cab

Why Choose the Carlo Gavazzi PD60CNK18BPT Contrast Sensor?

The Carlo Gavazzi PD60CNK18BPT is a high-speed fibre-optic photoelectric contrast sensor amplifier designed for precise detection of registration marks and surface contrast differences in industrial automation applications. As part of the Carlo Gavazzi PD60 photoelectric sensor series, it combines microprocessor-based sensing electronics with flexible NPN/PNP push-pull output technology for straightforward integration into modern machine control systems.

The PD60CNK18BPT is designed for use with plastic optical fibres and provides a nominal sensing distance of 18 mm, dependent on the selected fibre arrangement. Its high 20 kHz operating frequency enables rapid detection of contrast changes on fast-moving materials, making it particularly suitable for printing, packaging, labelling and production machinery.

Operating from a 10–30 V DC supply, the PD60CNK18BPT provides a push-pull NPN/PNP output with selectable NO/NC operation and a load capacity of up to 100 mA. The sensor amplifier is supplied with an integral 2 m cable and features a compact 13 × 30 × 60 mm polycarbonate housing with IP65 protection for dependable industrial operation.
