RI-25 Series Dry Reed Switch

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 Ib: 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.

ancy and reliability data. Further information is avail-

able on request.

Mechanical Data

Contact arrangement is normally open; lead finish is

tinned; net mass is approximately 190 mg; and can be

mounted in any position.

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 10 G; 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
