RI-60 SMD Series Dry Reed Switch

RI-60 SMD Series

Ultra-miniature dry-reed switch hermetically sealed in a gas-filled glass enve-

lope. 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 elec-

tromagnet, a permanent magnet or a combination of both. The device is

intended for use in relays, sensors, pulse counters or similar devices.

RI-60 SMD Series Features

▪ Ideal for ATE switching

▪ Contact layers: gold, sputtered ruthenium

▪ Superior glass-to-metal seal and blade alignment

▪ Excellent life expectancy and reliability

▪ RoHS Compliant

Dimensions for RI-60 SMD Series

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 & Applica-

tion 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-60 series.

No load conditions (operating frequency:

100Hz)

Life expectancy: min. 109 operations with a failure rate of

less than 2 x 10-10 with a confidence level of 90%.

End of life criteria:

Contact resistance > 1Ω after 2 ms

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

Loaded conditions (resistive load: 5 V; 100 mA;

operating frequency: 125 Hz)

Life expectancy: min. 2 x 107 operations with a failure rate

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

End of life criteria:

Contact resistance > 1Ω after 2.5 ms

Release time > 1 ms (latching or contact sticking).

Loaded conditions (resistive load: 20 V; 500

mA; operating frequency: 125 Hz)

Life expectancy: min. 2 x 107 operations with a failure rate

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

End of life criteria:

Contact resistance > 2Ω after 2.5 ms

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

Switching different loads involves different life expectancy

and reliability data. Further information is available on

request.

Mechanical Data

Contact arrangement is normally open; lead finish is

tinned; net mass is approximately 90mg; and can be

mounted in any position.

Shock

The switches are tested in accordance with “IEC 68-2-27”,

test Ea (peak acceleration 100 G, half sinewave; duration
