RI-07 Series Dry Reed Switch
RI-07 Series
Pico dry-reed switch hermetically sealed in a gas-lled glass envelope. Single-
pole, single-throw (SPST) type, having normally open contacts, and contain-
ing 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 relays, sensors, pulse counters or similar devices.
RI-07 Series Features
▪ Ideal general purpose reed relays and sensors
▪ Contact layers: ruthenium on gold
▪ 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-07 series.
No load conditions (operating frequency:
100Hz)
Life expectancy: min. 10

operations
End of life criteria:
Contact resistance > 2Ω after 4 ms
Release time > 0.7 ms (latching or contact sticking).
Switching dierent loads involves dierent life expectancy
and reliability data. Further information is available on
request.
