Photoelectric Sensors - Contrinex Inc


Now available from Contrinex is a new generation of photoelectric proximity switches designed to provide users with a high level of performance at competitive prices.

The 5050 series 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 meters and through-beam to 50 meters. They all have a high 1 kHz switched output frequency and can be supplied in either NPN or PNP versions with a two-meter 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 gain 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 and alerts 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 exceptional performance and competitive price make these high-quality sensors an extremely effective solution for many types of automation applications.
