RI-26 Series Dry Reed Switch

RI-26 Series

Close differential micro dry-reed switch hermetically sealed in a gas-filled

glass 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 electro-

magnet, a permanent magnet or a combination of both.

The device is intended for use in applications with small hysteresis in

switching behavior.

RI-26 Series Features

ꢀ

Close differential reed switch

Contact layers: gold, sputtered ruthenium

Superior glass-to-metal seal and blade alignment

Excellent life expectancy and reliability

Dimensions in inches (mm)

General data for all models RI-26

AT-Customization / Preformed Leads

Release time > 2ms (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

! Cropped and/or preformed leads

Loaded conditions (resistive load: 20 V; 500 mA;

operating frequency: 125 Hz)

Life expectancy: min. 5x10⁷operations with a failure

rate of less than 5x10^-9with a confidence level of 90%.

Coils

End of life criteria:

All characteristics are measured using the Philips

Standard Coil. For definitions of the Philips Standard

Coil, refer to “Application Notes” in the Reed Switch

Technical & Application Information Section of this

catalog.

Contact resistance > 2Ω after 2.5 ms

Release time > 2.5 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 1.5 times the published maximum operate

value for each type in the RI-26 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: 100 Hz)

Life expectancy: min. 3x10⁸operations with a failure

rate of less than 0.9x10^-9with a confidence level of

90%.

Shock

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

27”, test Ea (peak acceleration 50 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.

End of life criteria:

Contact resistance > 1Ω after 2ms
