Single-pole, double-throw (SPDT) type, having a normally open and a normally closed contact. The switch 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-90 Series Features Ideal for ATE switching & proximity sensors Contact layers: Ruthenium on gold Superior glass-to-metal seal and blade alignment Excellent life expectancy and reliability RI-90 Series Dry Reed Switch General data for all models RI-90 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 Stan- dard Coil, see 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 1.25 times the published maximum operate value for each type in the RI-90 series. No load conditions (operating frequency: 100Hz) Life expectancy : min. 108 operations with a failure rate of less than 2 x 10-9 with a confidence level of 90%. End of life criteria: Contact resistance > 1 Ω after 2 ms Release time > 2 ms (latching or contact sticking). Switching different loads involves different life expect- ancy and reliability data. Further information is avail- able on request. Operating and Storage Temperature Operating ambient temperature; min: -55°C; max: +125°C. Storage temperature; min: -55°C; max: +125°C. Note: Temperature excursions up to 150°C may be permissible. For more information contact your nearest Coto Technology sales office. Soldering 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 235°C; ageing 1b: 4 hours steam. Welding The leads can be welded. Dimensions in inches (mm) |
