RI-07AAA Datasheet, PDF (1/2 Pages) RHOPOINT COMPONENTS – SPST

RI-07 Series
RI-07 SERIES
Pico 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 relays, sensors, pulse counters or
similar devices.
RI-07 SERIES FEATURES
u Ideal for general purpose reed relays and sensors
u Contact layers: Gold/copper, sputtered or plated
ruthenium(can vary)
u Superior glass-to-metal seal and blade alignment
GENERAL DATA FOR ALL MODELS RI-07
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 and the
standard MIL Coil, refer to “Application Notes” in the Reed
Switch Technical & Application Information Section of this
catalog.
Relationship between Philips Standard Coil and the
Standard MIL Coil
Operate value of standard MIL Coil = 0.78 x operate value of
Philips Standard Coil + 1.02 AT.
Release value of standard MIL Coil = 0.83 x release value of
Philips Standard Coil + 0.01 AT.
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
f requency: 125 Hz)
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 > 1Ω after 2.5 ms
Release time > 1 ms (latching or contact sticking).
Loaded conditions (resistive load: 12V; 4 mA; (15 mA peak);
operating frequency: 170 Hz)
Life expectancy: min. 10⁶ operations
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-07 series.
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%.
End of life criteria:
Contact resistance > 2Ω after 4 ms
Release time > 0.7 ms (latching or contact sticking).
Switching different loads involves different life expectancy
and reliability data. Further information is available on
request.
