RI-02 SMD Series Dry Reed Switch
RI-02 (G1) SMD
RI-02 SMD 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 a combination of
both.
The device is intended for use in sensors, pulse counters or
similar devices and has the advantage that it can be manipu-
lated by automated pick and place machines.
RI-02 SMD Series Features
Ideal for General Purpose reed relays and sensors
Contact layers: ruthenium on gold
Superior glass-to-metal seal and blade alignment

General data for all models RI-02 SMD
Dimensions in inches (mm)
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
Coils
All characteristics are measured using the Philips
standard coil. For definitions of the Philips Standard
Coil, refer to the Reed Switch Technical & Application
Information Section of this catalog.
End of life criteria:
Contact resistance > 1Ω after 2 ms
Release time > 2ms (latching or contact sticking).
Loaded conditions (resistive load: 5V; 100 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 > 1Ω after 2.5 ms
Release time > 1 ms (latching or contact sticking).
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-02 series.
Switching different loads involves different life expect-
ancy and reliability data. Further information is avail-
able on request.
No-load conditions (operating frequency: 100 Hz)
Life expectancy: min.10⁸ operations with a failure rate
of less than 10^-9 with a confidence level of 90%.
Mechanical Data
Contact arrangement is normally open; lead finish is
tinned; net mass is approximately 90mg; and can be
mounted in any position.
