What Is Elevator Door Contacts?
Elevator door contacts refer to the contact components responsible for controlling the opening and closing of elevator doors. These contacts can be categorized into various types, such as the up-direction door contact, down-direction door contact, alarm door contact, and external call door contact.
Classification of Elevator Door Contacts
- Classification by Material
Elevator door contacts are typically made from materials such as copper alloy, copper-steel, and stainless steel. Copper alloy and copper-steel are commonly used due to their high electrical conductivity and strong oxidation resistance.
- Classification by Structure
Based on the structure of the elevator door switch, elevator door contacts can generally be divided into three types: direct type, spring type, and electromagnetic type.
- The direct type door contact refers to contacts that directly connect the circuit using metal pieces.
- The spring type door contact uses a metal spring to connect the circuit.
- The electromagnetic type door contact relies on an electromagnet for door opening and closing.
- Classification by Specifications and Parameters
The specifications and parameters of elevator door contacts typically include rated current, rated voltage, contact material, and contact resistance.
- Rated current and rated voltage are the primary parameters used to measure elevator door contacts and must match the circuit of the elevator.
- The contact material is a key factor in determining the quality of the contact, with common materials including copper alloy, copper-steel, and silver alloy.
- Contact resistance is an important parameter for judging the contact quality of elevator door contacts.
Specification Selection of Elevator Door Contacts
When selecting elevator door contacts, it is necessary to understand the specifications required by the elevator itself, such as current and voltage parameters. Additionally, the contact quality, stability, and reliability should be considered. Depending on the type of elevator door switch, the appropriate contact model and specification should be selected to ensure the normal operation of the elevator door.
Conclusion
Elevator door contacts are key components in the control of elevator door switches, directly affecting the safety and normal operation of the elevator. Choosing suitable door contacts can ensure accurate control of the elevator door. It is hoped that this article provides readers with a deeper understanding of elevator door contacts.
