PM-R44P PM-R44-P Sn5mm PNP Small U-shaped Micro Photoelectric Sensor OJ74

Description:
The PM-R44P is a small U-shaped micro photoelectric sensor engineered for precision close-range detection with a fixed 5 mm sensing distance. Capable of detecting opaque objects as small as 0.8 × 1.8 mm, it offers excellent repeatability and stability for micro-part presence detection, counting, and positioning. The built-in amplifier and PNP open-collector output enable fast signal transmission and compatibility with a wide range of control systems. Designed for demanding automation environments, the PM-R44P provides strong ambient light immunity, high vibration and shock resistance, and durable PBT construction. Its R-type housing and integrated 1 m cable make it ideal for compact equipment layouts.
