SUNX PM-T53B micro U-shaped photoelectric sensor
The SUNX PM-T53B is an ultra-compact U-shaped (slot type) photoelectric sensor measuring only 10.8 × 5.3 × 12.0 mm. Its one-piece fixed optical path needs no beam alignment. It detects opaque objects as small as 0.8 × 1.8 mm with a hysteresis (repeatability) of ≤0.05 mm and a response time as fast as 20 μs, making it well suited to precision turntable positioning, IC lead alignment and high-speed counting of small parts.
