Basic relay contacts parameters terminology

图片
1.Contact forms : they're the arrangements of relay contacts. The basic contact arrangements are shown in table below, the multi-contact arrangments can be ratiocinated. 2.Contact resistance : it is the total resistance between the contacts, the terminals and spring jointed with contacts, generally shown in mΩ. 3.Contact voltage drop : it generally is, in the load circuit, the total voltage drop between contacts,springs jointed with contact and the terminals. It is generally described as the voltage drop value under the regulated current, for example 50mV(measured in 10A). 4.Contact material : it is the material used in contacts and generally shown in chemistry formula, for example, AgNi represents silver-nickel alloy contacts.  5.Contact rated load : it generally refers to the load of which the contacts can switch reliably under the certain regulated conditions. Generally it is shown as the combination of the voltage and the current. The loads listed in the catalogue ar...
