''Voltage In:'' 3.8 V ~ 30 V

''Supply Current:'' 6mA

''Current Output (Max):'' 20mA

''Output Type'' Digital, Open Collector

''Field Intensity Max Operate'' +140 Gauss

''Field Intensity Min Release'' -140 Gauss

''Highlights:'' Ideal replacement for mechanical limit switches. Capable of using weak magnets rather than strong rare earth magnets.
