RI-60 Series
SERIES RI-60 SERIES Ultra-miniature 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 relays, sensors, pulse counters or similar devices. SERIES FEA EATURES RI-60 SERIES FEATURES u Ideal for ATE switching u Contact layers: Gold, sputtered ruthenium u Superior glass-to-metal seal and blade alignment u Excellent life expectancy and reliability

GENERAL DATA FOR ALL MODELS RI-60 -Customization Preformed efor AT-Customization / Pr eformed 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 C OILS All characteristics are measured using the Philips standard coil. For definitions of the Philips Standard Coil and the standard MIL Coil, refer to "Application Notes" in the Reed Switch Technical & Application Information Section of this catalog. Relationship between Standard Relationship betw een Philips Standard Coil and the Standard Standard MIL Coil Operate value of standard MIL Coil = 0.83 x operate value of Philips Sandard Coil + 0.30 AT. Release value of standard MIL Coil = 0.83 x release value of Philips Standard Coil + 0.18 AT.
EXPECTANCY 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.
(opera frequenc equency: No-load conditions (oper a ting frequenc y: 100 Hz) Life expectancy: min.109 operations with a failure rate of less than 2 x10-10 with a confidence level of 90%. End of life criteria: Contact resistance > 1 after 2 ms Release time > 2ms (latching or contact sticking). (resisti esistiv Loaded conditions (r esistive load: 5 V; 100 mA; opera frequenc equency: oper a ting frequency: 125 Hz) Life expectancy: min. 2 x 107operations with a failure rate of less than 10-8 with a confidence level of 90%. End of life criteria: Contact resistance > 1 after 2.5 ms Release time > 1 ms (latching or contact sticking). (resisti esistiv Loaded conditions (r esistive load: 20 V; 500 mA; opera frequenc equency: oper a ting frequency: 125 Hz) Life expectancy: min. 2 x 107 operations with a failure rate of < 10-8 with a confidence level of 90%.

End of life criteria: Contact resistance > 2 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. DA M ECHANICAL DATA Contact arrangement is normally open; lead finish is tinned; net mass is approximately 0.09 g; and can be mounted in any position. SHOCK The switches are tested in accordance with "IEC 68-227", test Ea (peak acceleration 100 G, half sinewave; duration 11 ms). Such a shock will not cause an open switch (no magnetic field present) to close. STRENGTH M ECHANICAL STRENGTH The robustness of the terminations is tested in accordance with "IEC 68-2-21", test Ua1 (load 10 N).
PERATING STORAGE EMPERATURE OPERATING AND ST ORAGE TEMPERATURE Operating ambient temperature; min: -55C; max: +125C. Storage temperature; min: -55C; max: +125C.
Note: Temperature excursions up to 150C may be permissible. For more information contact your nearest Coto Technology sales office. S OLDERING The switch can withstand soldering heat in accordance with "IEC 68-2-20", test Tb, method 1B: solder bath at 350 10 C for 3.5 0.5 s. Solderability is tested in accordance with "IEC 68-2-20" test Ta, method 3: solder globule temperature 235C; ageing 1b: 4 hours steam. W ELDING The leads can be welded. M OUNTING The leads should not be bent closer than 1 mm to the glass-to-metal seals. Stress on the seals should be avoided. Care must be taken to prevent stray magnetic fields from influencing the operating and measuring conditions.
