GENERAL SPECIFICATIONS
Operating Specifications
Switch Configurations:
• Closed Loop Switch closed when magnet is in close proximity
• Open Loop Switch open when magnet is in close proximity
• S.P.D.T. Switch has common, open and closed sides
• D.P.D.T. Two switches, each having common, open and closed sides
Gap Distances
Ratings are nominal and may vary ± 20%. Ratings are distance for switch to
“make.” Break distance is approximately 1.1 to 1.5 times the “make” distance.
Electrical Specifications
Rating Closed Loop Open Loop SPDT DPDT
Switching Voltage (Max.) 100V 30V 30V 30V
Switching Current (Max.) 0.5 Amp 0.25 Amp 0.25 Amp 0.25 Amp
Watts (Max.)(Volts x Amps) 7.5 Watts 3 Watts 3 Watts 3 Watts
Warning: Each electrical rating is an individual maximum and cannot be exceeded!
Example: Application at 100 VAC – 0.25 Amp would be 25 Watts and
would exceed the rating of the switch.
