Surface Mount Detection Switch
D3SH
The smallest detection switch in the
world. (OMRON’s data as of June 2006.)
• Ultra small size and ultra low profile contributing to
down-sizing of sets devices. (3.0 x 3.4 x 0.9 mm (W x D x H))
• A unique mechanism enables high contact reliability and
high precision operation.
• Horizontal 2-way detection and long stroke for easy
installation are available.
• Meet a variety of applications by contact and lever
variations.
