Photo interrupter, rather than contacts, ensures
high reliability. 1 million operations minimum.
Sealed construction for protection from environmental
elements, including hydrogen sulfide, sulfur dioxide,
and nitrogen hydroxide. Terminals are made of
ammonia-resistant materials.
Totally sealed body allows process compatibility for time-
and money-saving automatic soldering and cleaning.
Space-saving compact dimensions allow high density mounting.
Internal steel ball movement allows functionality of 360°
circumference rotation.
The DSB series switch is well-suited to meet product safety
concerns due to normally closed (on) status.
Crimped terminals ensure secure mounting and prevent dislodging
during wave soldering.
The switch is triggered when tilted beyond ±30° of the horizontal.

DSA
Environmentally friendly, contains no mercury.
High contact reliability due to sealed body.
The switch is triggered when tilted beyond ±10° of the horizontal.
PCB adaptor available as an accessory.
