Marktech's photo reflectors are sensors that contain both emitter and photo detector functions within a single package, emitting light from the sensor and reflecting it back to the detector side as an object enters the sensing area. This series is ideally suited for applications including edge sensing, line sensing, coin bill validation, and bar code reading.

Standard packaging is offered in a compact, high reliability, 4 mm plastic package with a wavelength range from 468 nm to 950 nm. Optimal operational distance ranges from 0.5 mm to 1.5 mm.
