The Retroreflective sensor ML7-55/25/103/143 is engineered for standard applications, equipped with a polarization filter and a front optical face. This sensor operates effectively within a range of 0 to 3 m, with a threshold detection capability of 3.5 m, utilizing a modulated visible red light LED as its light source.

The device features a compact design, measuring 31 mm in height, 23 mm in width, and 11 mm in depth, with a weight of approximately 10 g. It includes an M8 x 1 connector with 4 pins for connectivity. The sensor’s light spot diameter is roughly 180 mm at a distance of 3.5 m, with an opening angle of about 3°. It can function in ambient light conditions up to 40,000 Lux.

Electrical characteristics include an operating voltage of 10 to 30 V DC and a maximum no-load supply current of less than 20 mA. The sensor features a PNP output type, which is short-circuit protected and reverse polarity protected, with a maximum switching voltage of 30 V DC and a switching current of up to 100 mA. The switching frequency is 1000 Hz, with a response time of 0.5 ms.

It adheres to the product standard EN 60947-5-2 and is classified under protection class II. Operating temperatures range from -20 to 60 °C, with a storage temperature of -40 to 75 °C. The sensor is housed in a PC (glass-fiber-reinforced Makrolon) shell and is rated IP67/IP69K for protection against dust and water ingress. For operational safety, the device includes LED indicators for operation and function status.
