Mechanical Data
Contact arrangement is normally open; lead finish is
tinned; net mass is approximately 90mg; 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-
26”, 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-
RI-02 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 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.
