Accurately Detects Small-diameter Pins

Case Number 19

last update: November 4, 2009

This application uses a Spot-type Laser Photoelectric Sensor. 

The minute spot laser beam with maximum diameter of 1 mm accurately detects small-diameter pins.


Conventional photoelectric sensors with a large spot diameter could not be used for small-diameter pins. The system had a limited detection distance, which could damage the Sensor.

Benefit / Efficiency

Stable inspection of ultra-thin guide pins is possible in a small spot at a sensing distance as long as 1 m.
