Load Type
Choice List [Parts Count also]
The type of load on the device. Choices are:
Capacitive
Incandescent Lamp
Inductive
Resistive
Protection Level
Choice List
The type of protection level provided by the system. This does not refer to component hermeticity but rather to the protection level provided by the entire system. Choices are:
Hermetic
Sealed
Not Sealed
# of Single Pole Contacts
Integer
Not required for the following subcategories: Encoder Wheel and Rotary.
The number of ST (single throw) poles, where only the NO (normally open) contact is used.
# of Double Pole Contacts
Integer
Not required for the following subcategories: Encoder Wheel and Rotary.
The number of DT (double throw) poles, where the NO (normally open) and normally connected (NC) contacts are used.
# of Contacts
Integer [Parts Count and Parts Families also]
Required only for the following subcategories: Encoder Wheel and Rotary.
The number of poles or sets of contacts. For these two subcategories, all poles are counted as DT (double throw), regardless of the number of contacts per pole.
Breaking Capacity
Choice List
The current that the device is able to interrupt without being destroyed or causing an electric arc with unacceptable duration. Choices are:
< 2 Amp
= 2 Amp
Contact Type
Choice List
The type of contact. Choices are:
Gold
Silver
# of Actuations /h
Real
