Surface Mount Detection Switches
D3SK Surface Mount Detection Switch
The smallest detection switch in the
industry with high precision operation.
(OMRON's data as of April 2008.) (3.0 × 3.5 × 0.9 mm (W × D × H))
- Ultra small size and ultra low profile contributing
to down-sizing of sets devices.
- A unique mechanism enables high contact reliability
and high precision operation.
- Long stroke for easy installation is available.
- Meet a variety of applications by contact and lever
variatuions.
