Insulation resistance 1010 ohms
Operating temperature -40°F–240°F (-40°C–115°C)
OPTIONAL: SPNC or SPDT, 3 watt, 100VAC/VDC.
HYSTERESIS (Δ LIQUID LEVEL TO ACTIVATE/DEACTIVATE SWITCH)
≈ 3/8” (0.375″) max. travel
INDUCTIVE LOADS
Switch contacts have been tested with small relays and 30A J-C relay inductive driving coils at 120/240VAC to 500,000 operations without failure. Steady state driving coil Volt/Amp rating should be 8VA or less.
DRY CIRCUIT OPERATION
Switch can interface with microprocessor based controllers and related computer circuits.
NOTE: Model L-40 employs magnetic coupling between float arm and switch body. Magnetic particles can accumulate on and around magnetic housing which may affect proper operation. Please conduct appropriate fluid magnetic particle evaluation and operational tests prior to and during installation and use.
