RI-21 Series Dry Reed Switch

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 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

Operating and Storage Temperature

Operating ambient temperature; min: -55°C;

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

+125°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.

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.
