RM-1318 Reduced-miniature Reed Switch

Release AT configurable from 40% to 90% of operate AT

Glass sealed on round portion of wire for high seal strength

Flattened leads oriented to contact

Capable of switching 230V AC

RoHS Compliant and Lead-free

10-40 operate AT band

This reed switch is designed for applications where a size restriction is present, but higher load switching and current carrying capability is required. The blades have a good flexibility, for fast operation and good contact force, and can carry up to 1.5 A. The flattened leads are useful for orienting the internal blades to face one way while soldering, welding etc., for maximum in-group sensitivity. The three differential ranges available, cover a wide range of release AT specific applications. This reed switch can be supplied molded with a 0.25 mm wall around the glass capsule for use in hazardous industrial environments to withstand higher shock and vibration. This reed switch is completely Lead-free and conforms to the RoHS directive.
