AgSnO2 Silver Contacts
AgSnO2 Silver Contact factory, more than 12 years manufacture experience, attained ISO9001, work on OEM and ODM projects..
1. Introduction of AgSnO2 Silver Contacts
1. AgSnO2
is a nontoxic material, compared to AgCdO, and has very good and stable welding
resistance and arc erosion resistance.
2. It has better erosion resistance than AgCdO in the current range of 500 ~
3000 A, and shows better welding resistance than AgCdO and AgNi under lamp load
and capacitive load.
3. While under AC resistive load, the contact resistance of AgSnO2 is a little
higher than that of AgCdO, but it shows low and stable resistance at DC lamp /
motor loads (such as automobile relays).
4. Under DC condition, AgSnO2 has less material transfer compared to AgCdO.
5. Non-poisonous. It is a new and environment-friendly material used in contact
2. Application of AgSnO2 Silver Contacts
AgSnO2 electrical contacts are widely used in large capacity contactor, power relay, medium and small capacity of low voltage circuit breaker, and automobile electronics etc.
Ag(SnO2)10 is suitable for medium and small
current relay, Ag(SnO2)12 is suitable for medium- large current relay, Ag(SnO2)14
is suitable for high current relay and automotive relay
