Photoelectric proximity switches are competitively priced
Now available from Contrinex is a new generation of photoelectric proximity switches designed to provide a high level of performance at competitive prices.
The S5050 range is built in the widely used 50 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 4m and through-beam 50m. They all have a high 1kHz switched output frequency and can be supplied in either NPN or PNP versions with a 2m cable or an 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, thereby 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 10-36V DC supply range and are protected from short circuit, voltage reversal and supply transient spikes to ensure long and reliable operation in harsh environments. The specifications and competitive price make these Swiss-quality sensors an effective product for many types of automation applications.
