M-DW1 particular use sensor

Wafer mapping sensor.

Wafer mapping sensor

For more safety and more sensing accuracy, we studied the requirements for future wafer mapping sensors from various aspects. Our answer is the LED beam reflective type wafer mapping sensor M-DW1. This sensor uses LEDs as a light source for safe operation and 2-segment receiving element for more accurate position detection.


  • Precise position detection
  • Red light LED with fixed focus reflective beam
  • High-speed response time: 0.5ms
  • Off-delay timer selectable
  • Teach-in adjustment makes it user-friendly
  • 4 sensitivity levels are adjustable via DIP switch or external
  • Light ON/dark ON
