U-shaped type microphotosensors
|
|
This series sets a new standard for miniature photoelectric sensors. Not only their revolutionary size, but also the 17 different sensor shapes mean flexibility, space savings and quick installation on machinery. PM sensors are alternatively available as a cable type or as a crimp-connector version. They are equipped with two independent transistor outputs for light ON or dark ON operation. Characteristics: - Miniature construction
- Response time only 20µs
- Wide variety of models
- Connector or cable type
- Individual light ON/dark ON outputs
