RI-01C Series Dry Reed Switch

RI-01C Series

Pico dry-reed switch hermetically sealed in a gas-filled glass envelope.

Single-pole, single-throw (SPST) type, having normally open con-

tacts, 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-01C Series Features

Ideal for general purpose reed relays and sensors

Contact layers: ruthenium on gold

Superior glass-to-metal seal and blade alignment

General data for all models RI-01C

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, refer to

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-01C series.

No-load conditions (operating frequency: 100 Hz)

End of life criteria:

Contact resistance > 1

Ω after 2 ms

Release time > 2ms (latching or contact sticking).

Dimensions in inches (mm)

Loaded conditions (resistive load: 12V; 4 mA;

(15 mA peak); operating frequency: 170 Hz)

End of life criteria:

Contact resistance > 2

Ω 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.

Mechanical Data

Contact arrangement is normally open; lead finish is

tinned; net mass is approximately 100 mg; and can be

mounted in any position.

Shock

The switches are tested in accordance with “IEC 68-2-

27”, test Ea (peak acceleration 150 G, half 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.
