The Schneider Electric / Square D XUM0APSAM8 is a miniature rectangular photoelectric sensor from the XUM series. It uses multimode sensing — meaning the sensing method adapts to the target — and provides a maximum sensing distance of 14 m with a 2 ms response time. Output is PNP, rated for 100 mA continuous load over a 12-24V DC supply.
Rated IP65 and IP67, so it withstands washdown and temporary submersion. The rectangular plastic body measures 45 mm high, 12 mm wide, and 20 mm deep — sized for tight panel or machine mounting. Connection is via a 4-pin M8 connector; the PNP output uses NO/NC contacts (1NO/1NC). Ambient range is -13°F to 131°F.
