RI-02GP Series Dry Reed Switch
RI-02GP Series
Ultra-miniature dry-reed switch hermetically sealed in a gas filled envelope.
Single-pole, single-throw (SPST) type, having normally open contacts, and
containing two magnetically actuated reeds.
The switch is of the double-ended type and may be actuated by an
electromagnet, a permanent magnet or combination of both. The device is
intended for use in senors, relays, pulse counters or similar devices.
RI-02GP Series Features
Ideal for general purpose reed relays and sensors.
Contact layers: ruthenium on gold
Superior glass-to-metal seal and blade alignment
UL File #E125629
Dimensions for RI-02GP Series
All Dimension in inches (mm) nominal
General data for all models RI-02GP
AT-Customization / Preformed Leads
Besides the standard models, customized products can also
be supplied offering the following options:
• Operate and release ranges to customer specification
• Cropped and/or preformed leads
Life expectancy and reliability
The life expectancy data given below are valid for a coil
energized at 1.25 times the published maximum operate
value for each type in the RI-02GP series.
No load conditions (operating frequency: 100Hz)
Life expectancy: min. 108 operations with a failure rate of
less than 2 x 10-10 with a confidence level of 90%.
End of life criteria:
Contact resistance > 1Ω after 2 ms
Release time > 2 ms (latching or contact sticking).
Loaded conditions (resistive load: 5 V;
100 mA; operating frequency: 125 Hz)
Life expectancy: min. 2 x 106 operations with a failure rate
of less than 10-8 with a confidence level of 90%.
End of life criteria:
Contact resistance > 1Ω after 2.5 ms
Release time > 1 ms (latching or contact sticking).
Loaded conditions (resistive load: 20 V;
500 mA; operating frequency: 125 Hz)
Life expectancy: min. 2 x 106 operations with a failure rate
of less than 10-7 with a confidence level of 90%.
End of life criteria:
Contact resistance > 2Ω after 2.5 ms
Release time > 2.5 ms (latching or contact sticking).
Switching different loads involves different life expectancy
and reliability data. Further information is available on
request.
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 100 G; half sinewave; duration
11ms). Such a shock will not cause an open switch (no

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-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 10 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.
