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  RoHS Compliant and Lead-free  Not Sensitive to ESD  20-50 Operate AT band


This reed switch is designed for performance at moderate inductive loads of 15W. The flattened leads are especially useful for orienting the internal blades to face one way while soldering, welding etc, for maximum in-group sensitivity. The two differential AT bands which are available cover a wide range of release AT specific applications. 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: coffee machines, water tank control, digital wind vanes, rowing electronics, electronics and science kits
