Banner Engineering BRT-51x51BM 71791 Photoelectric Sensor

Banner Engineering BRT-51X51BM (71791) is a square retroreflective target reflector with a 51 × 51 mm reflective aperture, built around a microprism element for a reliable return to compatible retroreflective sensing systems. The reflector uses acrylic as the reflective material and measures approximately 61 × 51 mm in a plastic housing with a mounting screw hole for straightforward installation. Key specs include a maximum operating temperature of 60 °C, polarized sensing capability, and laser compatibility, making it suitable for use with polarization-sensitive and laser-based retroreflective sensors. The reflective window is 51 × 51 mm, while the overall package is about 61 × 51 mm; CAD files (DXF, IGS, STP) and a data sheet are available for design integration. This item is identified by Banner part number 71791 and is cataloged as a retroreflective target reflector within Banner’s sensing family, designed to pair with appropriate Banner amplifiers where applicable.
