RI-80 Datasheet, PDF (1/2 Pages) Coto Technology – Dry Reed Switch

RI-80 Series Dry Reed Switch
RI-80 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.
The device is intended for use in sensors, relays, pulse counters or
similar devices.
RI-80 Series Features

World’s smallest high quality reed switch
Contact layers: gold, sputtered ruthenium
Superior glass-to-metal seal and blade alignment
Dimensions in inches (mm)
General data for all models RI-80
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
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: 170 Hz)
Coils
All characteristics are measured using the Philips
Standard Coil. For definitions of the Philips Standard
Coil, see Reed Technical & Application Information
Section of this catalog.
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.
Life expectancy: min. 10⁷ operations with a failure
rate of less than 10^-8 with a confidence level of 90%.
End of life criteria:
Contact resistance > 2Ω after 4 ms
Release time > .7 ms (latching or contact sticking)
Switching different loads involves different life expect-
ancy and reliability data. Further information available
upon request.
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%.
Mechanical Data
Contact arrangement is normally open; lead finish is
tinned; net mass is approximately 65mg; and can be
mounted in any position.
