mounted in any position.
Shock
e switches are tested in accordance with “IEC 68-2-27”,
test Ea (peak acceleration 100 G; half sinewave; duration
11ms). Such a shock will not cause an open switch (no
magnetic eld present) to close, nor a switch kept closed
by an 80 AT coil to open.
Vibration
e switches are tested in accordance with “IEC 68-2-26”,
test Fc (acceleration 10G; below cross-over-frequency 57
to 62 Hz; amplitude 0.75 mm; frequency range 10 to
2000 Hz; duration 90 minutes.) Such a vibration will not
cause an open switch ( no magnetic eld present) to close,
nor a switch kept closed by an 80 AT coil to open.
Mechanical Strength
e robustness of the terminations is tested in accordance
with “IEC 68-2-21”, test Ua1 (load 10 N).
Operating and Storage Temperature
Operating ambient temperature; min: -55°C; max:
+125°C. Storage temperature; min: -55°; max: +125°C.
Note: Temperature excursions up to 150°C may be
permissible. For more information contact your nearest
Comus Group sales oce.
Soldering
e switch can withstand soldering heat in accordance
with “IEC 68-2-20”, test Tb, method 1B: solder bath at
350 ± 10°C for 3.5 ± 0.5 s. Solderability is tested in acc
ordance with “IEC 68-2-20” test Ta, method 3: solder
globule temperature 235°C; ageing 1b: 4 hours steam.
Welding
e leads can be welded.
Mounting
e leads should not be bent closer than 1 mm to the
glass-to-metal seals. Stress on the seals should be avoided
Care must be taken to prevent stray magnetic elds from
inuencing the operating and measuring conditions.
