AT-Customization / Preformed Leads

Besides the standard models, customized products

can also be supplied offering the following options:

! Operate and release ranges to customer

! Cropped and/or preformed leads

Coils

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.

RI-03 Series Features

RI-03 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.

Ideal for general purpose reed relays and sensors

ruthenium (can vary)

Contact layers: Gold/copper, sputtered or plated

Superior glass-to-metal seal and blade alignment

End of life criteria:

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

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

Life expectancy: min. 10

of less than 10

End of life criteria:

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 190 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

Contact resistance > 1Ω after 2 ms

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

Contact resistance > 2Ω after 4 ms

Release time > 0.7 ms (latching or contact sticking).
