Vibration
The switches are tested in accordance with “IEC 68-2-
6”, test Fc (acceleration 10G; below cross-over fre-
quency 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 Ua

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.
