Honeywell recommends allowing 10 µs for output voltage to stabilize after supply voltage has reached its normal operating value. N O TICE The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field. Table 2. SS360PT/SS460P Absolute Maximum Ratings1 Characteristic MIn. Typ.
