General data for all models RI-08

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 “Application Notes” in the Reed Switch

Technical & Application Information Section of this

catalog.

Life expectancy and reliability

The life expectancy data given below are valid for a coil

energized at 1.5 times the published maximum operate

value for each type in the RI-08 series.

No-load conditions (operating frequency: 100 Hz)

Life expectancy: min. 10

of less than 10

End of life criteria:

Contact resistance > 1Ω after 2 ms

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

RI-08 Series

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

electromagnet, a permanent magnet or a combination of both.

The device is intended for use in sensors, relays, pulse counters or similar

devices.

RI-08 Series Features

Can switch main voltage

Can handle up to 40W load

Contact layers: Ruthenium on gold

Superior glass-to-metal seal and blade alignment

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

operating frequency: 125 Hz)

RI-08AA

Life expectancy: min. 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 280 mg; and can be

mounted in any position.

Shock

The switches are tested in accordance with “IEC

68-2-27”, test Ea (peak acceleration 500 G, half

sinewave; duration 11 ms). Such a shock will not cause

an open switch (no magnetic field present) to close,

Contact resistance > 2Ω after 2.5 ms

Release time > 2.5 ms (latching or contact sticking).
