PM-K44P PM-K44-P Sn5mm PNP Small U-shaped Micro Photoelectric Sensor OJ75

Description:
The PM-K44P is a compact U-shaped micro photoelectric sensor featuring a fixed 5 mm sensing range and built-in amplifier, designed for precise detection in miniature automation equipment. Its PNP open-collector output provides fast and stable signal transmission suitable for modern control systems. With the ability to detect opaque objects as small as 0.8 × 1.8 mm, the PM-K44P-C3 is ideal for micro-part detection, counting, positioning, and robotic assembly tasks. The sensor delivers high repeatability, strong ambient light immunity, and excellent resistance to vibration and shock, ensuring stable operation in demanding industrial environments. The K-type housing with a 3 m cabtyre cable offers flexible installation options for tight machinery layouts.
