RI-80 SMD Series Dry Reed Switch

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;

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.

* 200V for switches with AT-on value > 10AT.

** AT values of switches before SMD forming in PSC coil.
