RI-80 Series Dry Reed Switch
RI-80 Series
Ultra-micro dry-reed switch hermetically sealed in a gas-lled glass envelope.
Single-pole, single-throw (SPST) type, having normally open contacts, and
containing two magnetically actuated reeds.
e switch is of the double-ended type and may be actuated by an elec-
tromagnet, a permanent magnet or a combination of both. e device is
intended for use in sensors, relays, pulse counters or similar devices.
RI-80 Series Features
▪ Ideal for ATE switching, proximity sensors & medical applications
▪ Contact layers: gold, sputtered ruthenium
▪ Superior glass-to-metal seal and blade alignment
▪ RoHS Compliant

AT-Customization / Performed Leads
Besides the standard models, customized products can also
be supplied oering the following options:
• Operate and release ranges to customer specication
• Cropped and/or performed leads
Coils
All characteristics are measured using the Philips Standard
Coil. For denitions of the Philips Standard Coil, refer to
“Application Notes” in the Reed Switch Technical & Applica-
tion Information Section of this catalog.
Life expectancy and reliability
e 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-80 series.
No load conditions (operating frequency:
100Hz)
Life expectancy: min. 10
8
operations with a failure rate of
less than 2 x 10
-9
with a condence 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: 5V; 100 mA;
operating frequency: 170 Hz)
Life expectancy: min. 10
7
operations with a failure rate of
less than 10
-8
with a condence level of 90%.
End of life criteria:
Contact resistance > 2Ω after 4 ms
Release time > .7 ms (latching or contact sticking)
Switching dierent loads involves dierent life expectancy
and reliability data. Further information available upon
request.
Mechanical Data
Contact arrangement is normally open; lead nish is
tinned; net mass is approximately 65mg; and can be
mounted in any position.
Shock
e 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 eld present) to close, nor a switch kept closed
