RI-23 Series Dry Reed Switch

RI-23 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.

RI-23 Series Features

ꢀ

General purpose reed switch

Contact layers: gold, plated ruthenium

Superior glass-to-metal seal and blade alignment

Excellent life expectancy and reliability

Dimensions in inches (mm)

General data for all models RI-23

AT-Customization / Preformed Leads

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

Besides the standard models, customized products

can also be supplied offering the following options:

! Operate and release ranges to customer

specification

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

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

Life expectancy: min. 10⁷operations with a failure rate

of less than 10^-8with a confidence level of 90%.

! 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-23 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

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.

Life expectancy : min. 10⁸operations with a failure

rate of less than 10^-9with a confidence level of 90%.

End of life criteria:

Contact resistance > 1Ω after 2 ms
