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 accordance

with “IEC 68-2-21”, test Ua1 (load 40 N).

Operating and Storage Temperature

Operating ambient temperature; min: -55°C; max:

+125°C. Storage temperature; min: -55°; max: +125°C.

Note: Temperature excursions up to 150°C may be

permissible. For more information contact your nearest

Comus Group 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.
