The switches are tested in accordance with “IEC 68-2-27”,
test Ea (peak acceleration 500 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.

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; 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.

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.

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 influ-
encing the operating and measuring conditions.
Note 1: Switching higher currents is possible depending on signature of the load.
