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.
