RI-80 SMD Series Dry Reed Switch
RI-80 SMD Series
Ultra-micro dry-reed switch hermetically sealed in a gas-filled glass
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.

General data for RI-80 SMD
AT-Customization
The RI-80 SMD can be supplied in operate ranges to
customer specification.
Life expectancy: min. 107 operations with a failure
rate of less than 10-8 with a confidence level of 90%.
End of life criteria:
Coils
Contact resistance > 1Ω after 4 ms
Release time > .7 ms (latching or contact sticking)
All characteristics are based on unmodified switches.
The switches are defined using the Philips Standard
Coil. For more information, see Reed Switch Technical
& Application Information Section of this catalog.
Switching different loads involves different life expect-
ancy and reliability data. Further information available
upon request.
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-80 series.
Mechanical Data
Contact arrangement is normally open; lead finish is
tinned; and can be mounted in any position.
No-load conditions (operating frequency: 100 Hz)
Life expectancy: min. 108 operations with a failure rate
of less than 2 x10-9 with a confidence level of 90%.
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.
End of life criteria:
Contact resistance > 1Ω after 2 ms
Release time > 2ms (latching or contact sticking).

Soldering
Vibration
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.
The switches are tested in accordance with “IEC
68-2-6”, 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.
Welding
The leads can be welded.
Mechanical Strength
The robustness of the terminations is tested in accor-
dance with “IEC 68-2-21”, test Ua1 (load 10N).
