RI-01B Series Dry Reed Switch
RI-01B Series
Micro dry-reed switch hermetically sealed in a gas-filled 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.

General data for all models RI-01B
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
End of life criteria:
Contact resistance > 1Ω after 2 ms
Release time > 2 ms (latching or contact sticking).
Loaded conditions (resistive load: 12 V; 4 mA;
(15 mA peak); operating frequency: 170 Hz)
Life expectancy: min. 106 operations.
! Cropped and/or preformed leads
Coils
End of life criteria:
All characteristics are measured using the Philips
Standard Coil. For definitions of the Philips Stan-
dard Coil, refer to “Application Notes” in the Reed
Switch Technical & Application Information Section of
this catalog.
Contact resistance > 2Ω after 4 ms
Release time > 0.7 ms (latching or contact sticking).
Switching different loads involves different life expect-
ancy and reliability data. Further information is avail-
able on request.
Life expectancy and reliability
Mechanical Data
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-01B series.
Contact arrangement is normally open; lead finish is
tinned; net mass is approximately 190 mg; and can be
mounted in any position.
No load conditions (operating frequency:
100Hz)
Shock
The switches are tested in accordance with
“IEC 68-2-27”, test Ea (peak acceleration 150 G, half
Life expectancy : min. 108 operations with a failure
rate of less than 10-9 with a confidence level of 90%.

* The Contact Resistance is measured using the Kelvin Method next to the glass body.
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.
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.
Vibration
The switches are tested in accordance with “IEC
68-2-6”, test Fc (acceleration 10G; below cross-over
frequency 57 to 62 Hz; amplitude 0.75 mm;
frequency range 10 to 2000 Hz, duration 90 minutes).
Such a vibration will not cause an open switch (no
magnetic field present) to close, nor a switch kept
closed by an 80 AT coil to open.
Welding
The leads can be welded.
Mounting
The leads should not be bent closer than 1 mm to the
glass-to-metal seals. Stress on the seals should be
avoided. Care must be taken to prevent stray magnetic
fields from influencing the operating and measuring
conditions.
Mechanical Strength
The robustness of the terminations is tested in accor-
dance with “IEC 68-2-21”, test Ua1 (load 40 N).
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
