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.• Rated operating distance sn - LED 648 nm (red) • Emitter - 15 kHz • Modulation frequency - 10 ... 36 VDC • Supply voltage range UB - 20% max. • Max. ripple content - 200 mA max. • Output current (sum) - 2.0 V at 200 mA • Output voltage drop - 15 mA max. • No-load supply current - 0.1 mA max. • Leakage current - 1 kHz • Switching frequency - 0.5 msec max. • Switching time - 50 msec • Time delay before availability - Potentiometer • Sensitivity setting - -5 ... +55 C (+23 ... + 131 F) • Ambient temperature range - Built-in • Short-circuit protection - Built-in • Voltage reversal protection - Built-in • Induction protection - IP 65 • Degree of protection - ABS • Housing material - PMMA • Window material - PVC 4 x 0.25 mm2 / 128 x 0.25 mm Ø; 2 m • Connection cable- S8 4p
