RI-90 Series
Micro changeover dry-reed switch hermetically sealed in a gas-filled
envelope. Single-pole, double-throw (SPDT) type, having a normally
open and a normally closed contact.
The switch 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-90 Series Features
Ideal for ATE switching & proximity sensors
Contact layers: Ruthenium on gold
Superior glass-to-metal seal and blade alignment
Excellent life expectancy and reliability
RI-90 Series Dry Reed Switch
General data for all models RI-90
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 Stan-
dard Coil, see
Reed Switch 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-90 series.
No load conditions (operating frequency:
100Hz)
Life expectancy : min. 108 operations with a failure
rate of less than 2 x 10-9 with a confidence level of
90%.
End of life criteria:
Contact resistance > 1
Ω after 2 ms
Release time > 2 ms (latching or contact sticking).
Switching different loads involves different life expect-
ancy and reliability data. Further information is avail-
able on request.
Operating and Storage Temperature
Operating ambient temperature; min: -55°C;
max: +125°C. Storage temperature; min: -55°C; max:
+125°C. Note: Temperature excursions up to 150°C
may be permissible. For more information contact your
nearest Coto Technology sales office.
Soldering
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.
Welding
The leads can be welded.
