Shock
The switches are tested in accordance with “IEC
68-2-27”, test Ea (peak acceleration 150 G, half
sinewave; duration 11 ms). 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.
Vibration
The switches are tested in accordance with “IEC
68-2-6”, 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 field present) to close, nor a switch
kept closed by an 80 AT coil to open.
Mechanical Strength
The robustness of the terminations is tested in accor-
dance with “IEC 68-2-21”, test Ua1 (load 10N).
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. For more information contact your nearest
Coto Technology sales office.
Soldering
The 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 accordance with “IEC 68-2-
20” test Ta, method 3: solder globule temperature
235°C; ageing 1b: 4 hours steam.
Welding
The leads can be welded.
Mounting
The 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
fields from influencing the operating and measuring
conditions.
