Features and applications: 1.A dry- reed compact low weight Reed black part dimensions 14.5 x 4mm (total length 41 x 4mm),can be installed in extremely limited space the device is very suitable for miniaturization . 2. The dry- reed switch components are hermetically sealed in an inert gas atmosphere is never in contact with the external environment and long working life. 3. Dry reed pipe does not use the sliding element; it will not appear in all metal -related metal fatigue phenomenon downgrading to ensure virtually no limit mechanical life. 4.The reed switch in the phone PBX photocopiers washing machines refrigerators cameras sterilized cupboard door window magnetic electromagnetic relays electronic weighing level gauge gas meter water meter and so on have been very good application . Reed Caution: 1. Cutting or benting reed lead foot must be extremely careful to avoid undue stress leaving the glass - metal seals were damaged . Appropriate clamping of the tool must be used 2. Encountered temperatures and long exposure time might cause the glass - metal seal damage (cracking leaks etc.) and therefore must be fast and reliable welding technology (process). Recommended soldering conditions: when hand soldering 280 ~ 300 ° C Wave Solder 250 to 300 ° C.
