Highlights

♦ 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 ♦ Sputtered Ruthenium contact Capable of switching 230VAC ♦ RoHS Compliant and Lead-free ♦ Not Sensitive to ESD ♦ 10-40 Operate AT band

Description

This reed switch is designed for applications where a size restriction is present, but a higher Contact Rating and Carry Current 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.

Applications

This reed switch is suitable for use in the following applications and in many others: radio transmitters, instant water heaters, defective lamp detection, inclination sensors, pressure gauges, lake current measurement, fuel pumps, electric fishing reels, LEGO sensors
