Photoelectric proximity switches from Contrinex

The S5050 range is built in the widely used 50mm x 50mm format and is available in diffuse, retro-reflective (reflex) and through-beam versions. Each of these configurations has a long sensing distance; diffuse at 800mm, retro-reflective up to four metres and through-beam 50 metres. They all have a high 1 kHz switched output frequency and can be supplied in either NPN or PNP versions with a two-metre cable or a S8 four-pin plug configuration. The lens window material is PMMA plastic making the sensors suitable for use in the food and pharmaceutical industries.

A diagnostic or ‘excess’ function can be selected with each sensor type that monitors the visible red light detected. This provides a switched output if the light level falls below a safe threshold thus alerting users to dirt build-up or any misalignment occurring after installation. It also simplifies adjustment and set-up during installation.

All of the new S5050 products have a wide 10 – 36VDC supply range and are protected from short-circuit, voltage reversal and supply transient spikes to ensure long and reliable operation in harsh environments. The high specifications and highly competitive price make these Swiss-quality sensors an extremely effective solution for many types of automation applications.
