NKK Switches' environmentally friendly DS Series of mercury-free tilt sensor switches is engineered to replace mercury and pendulum switches. DS Series sensor switches use photo interrupters instead of conventional contacts to ensure high reliability and sensitivity to very small angle changes.
The series features sealed construction for protection from environmental elements including hydrogen sulfide, sulfur dioxide and nitrogen hydroxide. The sensor switch has a completely sealed body to allow process compatibility for automated soldering and cleaning. Terminals are made of ammonia resistant material and are crimped to ensure secure PCB mounting and prevent dislodging during wave soldering.
