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 10 G; below cross-over
frequency 57 to 62 Hz; amplitude 0.75 mm; fre-
quency range 10 to 2000 Hz, duration 90 minutes in
each direction). 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
accordance with “IEC 68-2-21”, test Ua
Operating and Storage Temperature
Operating ambient temperature; min: -55°C; max:
+75°C. Storage temperature; min: -55°C; max:
+125°C.

may be permissible. For more information contact

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.
