SUNX PSS-500D Diffuse Reflective Photoelectric Sensor

SUNX PSS-500D Diffuse Reflective Photoelectric Sensor is a SUNX by Panasonic diffuse‑reflective sensing device designed for non‑contact detection of opaque targets within a mid‑range reach. As a diffuse reflective sensor, it emits light and detects objects from light reflected off the target’s surface, eliminating the need for a separate reflector in many setups. The PSS‑500D belongs to the PSS‑500 family, a line known for its slim, space‑saving form factor and mid‑range detection capabilities; the related PSS‑500 model lists a sensing distance up to 500 mm and operates on a 12–24 V DC supply with an open‑collector output, with typical emitter current under 25 mA and receiver current under 20 mA. This makes the PSS‑500D suitable for compact automation environments such as conveyors, packaging lines, and small‑parts handling where quick presence/absence checks or edge detection are needed. Applications often include detecting parts on conveyors, verifying finished goods presence, and ensuring correct positioning in assembly cells, where a simple, compact photoelectric solution can replace more bulky sensors.
