Shock

The switch are tested in accordance with "IEC 68-2-27", test Ea ( peak acceleration 500G, half sinewave; duration 11ms). Such a shock will not cause an open switch ( no magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open.

Operating and Storage Temperature

Operating ambient temperature; min: -55°C; max: +125°C. Storage temperature; min: -55°C; max: +125°C. Note: Temperature excursions up to 150°C may be permissible.
