RI-80-SMD Datasheet, PDF (1/2 Pages) Coto Technology – Dry Reed Switch
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.
RI-80 SMD Series Features
Ideal for proximity sensors, telecom & medical applications
World’s smallest high quality reed switch
Contact layers: Gold, sputtered ruthenium
Superior glass-to-metal seal and blade alignment
Dimensions in inches (mm)
RI-80 SMD G1 Model
RI-80 SMD G2 Model
RI-80 SMD J-Lead Model
General data for RI-80 SMD
AT-Customization
The RI-80 SMD can be supplied in operate ranges to
customer specification.
Loaded conditions (Resistive load: 5V; 100 mA;
operating frequency: 170 Hz)
Life expectancy: min. 107 operations with a failure
rate of less than 10-8 with a confidence level of 90%.
Coils
All characteristics are based on unmodified switches.
The switches are defined using the Philips Standard
End of life criteria:
Contact resistance > 1Ω after 4 ms
Release time > .7 ms (latching or contact sticking)
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
Life expectancy and reliability
upon request.
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
End of life criteria:
Contact resistance > 1Ω after 2 ms
Release time > 2ms (latching or contact sticking).
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.
