Breakdown voltage configurable from 350V to 600V  Round glass and wire for maximum seal strength  Sputtered Ruthenium contact  RoHS Compliant and Lead-free  Not Sensitive to ESD  20-60 Operate AT band


This reed switch is designed with highly flexible blades to get maximum contact gap at lower AT ranges, and consequently having high break down characteristics. The two types of contacts options available provide breakdown at 350V or 500V minimum. Higher Ampere Turn groups will have even higher breakdown voltage values. Another added advantage is that these reed switches can be used in application with vibration as slight blade movement when using lower AT bands will not cause unwanted closures. This reed switch is completely Lead-free and conforms to the RoHS directive.


This reed switch is suitable for use in the following applications and in many others: relays in food processors, power switches in explosive areas, magnetic extensometers
