Very low hysteresis / close differential operation  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  10-40 Operate AT band


This Form A reed switch is built with specially pressed blades with slightly higher rigidity for close differential, low hysteresis applications where an operate and release is required with minimum magnet travel, or minimum change in coil voltage. It also uses a glass tube with a higher wall thickness and is very robust. 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:  automobile seatbelt sensorsautomobile coolant flow sensingdigital wind vanes, ferrous metal detection sensorsgear speed and direction sensors
