E39-R4 Reflector for Retro-Reflective Photoelectric Sensors, 23 x 13.7 mm - 1 pc

The E39-R4 reflector is a compact rectangular reflective target commonly listed for use with E3T and E3S series retro-reflective photoelectric sensors. Distributor and reseller references identify the part as E39-R4 and describe a small acrylic corner-cube style reflector with approximate dimensions of 23 × 13.7 mm. When used with compatible miniature retro-reflective sensors, catalog examples show sensing distances up to about 200 mm (refer to the sensor datasheet for exact performance). This listing is for one E39-R4 reflector; please confirm your sensor model and part number before ordering to ensure correct fit.
