ds ordering information highly sensitive 1500 v fcc surge breakdown vo lta ge miniature relay ds relays rohs directive compatibility information http://www.mew.co.jp/ac/e/environment/ features 1. breakthrough height of 9.8 mm .386 inch beats the 10 mm .394 inch limit 1c, 2c, and 4c all have the same height (9.8 mm .386 inch ). the width of the relay is also the same (9.9 mm .390 inch ). since the only size variable is the length, the shared form makes mounting on printed printing wiring boards easy. 2. suitable for use in dif?ult environments epoxy resin seals the parts and cut off the external atmosphere, thus enabling use in dif?ult environments. 3. can be used with automatic solder and automatic wash systems automatic soldering and automatic washing can be carried out once the parts are mounted on pc boards. 4. gold-clad twin contacts ensure high reliability highly stable gold cladding on the contacts ensures that contact resistance changes little over time. furthermore, the use of twin contacts, a con?uration that performs with superior contact reliability, ensures extremely low contact failure rates even under low level loads. 5. polarized magnetic circuits realize resistance to shock and vibration high-performance polarized magnetic circuits that utilize the energy of permanent magnets have made it possible to create relays with strong resistance to shock and vibration. 6. dil terminal array enables use of ic sockets 7. widening scope of application with multicontact latching in addition to single side stable types, you can take advantage of the memory of functions of convenient 1 coil or 2 coil latching relays. typical applications besides telecommunications, measuring devices, of?e equipment, computers and related equipment, ds relays are also recommended for a broad range of applications including business devices, audio systems, and industrial equipment. coil voltage dc 1.5, 3, 5, 6, 9, 12, 24, 48 v contact arrangement 1: 1 form c 2: 2 form c 4: 4 form c ds e operating function nil: l: l2: single side stable 1 coil latching 2 coil latching sensitivity m: s: 400 mw nominal operating power 200 mw nominal operating power nil: r: standard polarity type reverse polarity type note: 1 coil latching type are manufactured by lot upon receipt of order. reverse polarity types available (add suffix-r) all rights rese r v ed c o p y r i gh t matsushita elect r ic w o r k s , ltd.
