RI-06 series features close differential reed switch contact layers: ruthenium on gold superior glass-to-metal seal and blade alignment general data for all models RI-06 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-06 series. no load conditions (operating frequency: 100hz) life expectancy : min. 10 8 operations with a failure rate of less than 10 -9 with a confidence level of 90%. end of life criteria: contact resistance > 1 ? after 2 ms release time > 2 ms (latching or contact sticking). loaded conditions (resistive load: 12 v; 4 ma; (15 ma peak); operating frequency: 170 hz) life expectancy: min. 10 6 operations. end of life criteria: contact resistance > 2 ? after 4 ms release time > 0.7 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 190 mg; and can be mounted in any position. dimensions in inches (mm)
135 for most recent data, consult the coto technology website: www.cotorelay.com e-mail: sales@cotorelay.com RI-06 series dry reed switch shock the switches are tested in accordance with ?iec 68-2- 27?, test ea (peak acceleration 150 g, half sinewave; duration 11 ms). such a shock will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 at coil to open. vibration the switches are tested in accordance with ?iec 68-2- 6?, test fc (acceleration 10g; below cross-over fre- quency 57 to 62 hz; amplitude 0.75 mm; frequency range 10 to 2000 hz, duration 90 minutes). such a vibration will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 at coil to open. mechanical strength the robustness of the terminations is tested in accor- dance with ?iec 68-2-21?, test ua 1 (load 40 n). operating and storage 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. 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 235c; ageing 1b: 4 hours steam. welding the leads can be welded. mounting 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.
