Panasonic RX-LS200 Reflective Photoelectric Sensor

Panasonic RX-LS200 is an adjustable-range reflective photoelectric sensor with a built-in amplifier from the SunX RX series. It detects targets at 50 to 200 mm, tested with a white non-glossy 50 × 50 mm reference, and features 10% or less hysteresis; repeatability is 1 mm along the sensing axis and 0.5 mm perpendicular, ensuring stable switching as the object moves within range. Available in two output configurations—RX-LS200 (NPN) and RX-LS200-P (PNP)—to match different controller inputs, and it is CE-marked with EMC and RoHS compliance. This model is discontinued; Panasonic notes the last time buy was September 30, 2022. The RX-LS200 supports retroreflective and diffuse reflective sensing, with typical setting distances illustrated around 150–200 mm depending on target size and surface finish, including options to use a slit mask to tune the effective range. As part of Panasonic Industry SUNX, it provides an internally amplified sensor head designed for reliable operation in industrial environments, enabling straightforward integration with common automation circuits without external amplifiers.
