PM-T44 Sn 5mm NPN Small U-shaped Micro Photoelectric Sensor OJ73

Description:
The PM-T44 is a small U-shaped micro photoelectric sensor designed for precision close-range detection in compact automation systems. With a fixed sensing range of 5 mm, it reliably detects small opaque targets as small as 0.8 × 1.8 mm. Its built-in amplifier enables fast, stable performance suitable for high-speed counting, positioning, and micro-part presence sensing. The T-type body design provides easy mounting in constrained equipment layouts. Combined with high ambient light immunity, excellent repeatability, and durable construction, the PM-T44 is ideal for robotics, assembly mechanisms, inspection units, and miniature industrial machinery.
