It feels smooth and natural for the people inside when an elevator starts and stops without any delay. Most passengers never think about what controls this steady movement. A small device inside the control panel takes care of this work. It is called the contactor.
This small part plays a major role in the safe and steady working of your lift. This is why building teams search for trusted elevator control panel parts UAE to keep their elevators safe and ready at all times.
Bestech supplies high-quality contactors that match the power needs of modern lift systems. As a trusted elevator contactor supplier UAE, they make sure building owners and lift service teams get reliable parts that support daily lift movement.
What Does a Contactor Do in an Elevator
A contactor acts like a switch that is controlled by the elevator controller. When the lift needs to move, the contactor pulls its coil and closes its contacts. This allows power to reach the motor.
When the lift stops, the contactor releases and opens the circuit, cutting off the power. In simple words, the contactor manages power entry and power cut at the right time.
Without a working contactor, the motor cannot start and the door unit may fail to operate. The control system may show errors, and the lift can even stop between floors. This shows how the contactor supports safe lift movement every day.
How a Contactor Works Inside the Control System
The working method is simple. The coil inside the contactor creates magnetic force when power flows through it. This force pulls the contacts together and completes the circuit.
Once the lift reaches the required floor, the control system removes power from the coil. The magnetic force drops and the contacts open, stopping the power flow.
This open-and-close action happens many times a day. This is why contactors must be strong enough to handle long-term use. Bestech supplies contactors that fit well with different elevator motor control parts and modern lift control panels.
AC Contactors vs DC Contactors
Both AC and DC contactors are used in lift systems based on the design of the elevator.
AC Contactors
AC contactors are used for motors and systems that run on AC power. They can handle high power loads, making them suitable for lift motors in both residential and commercial buildings. These contactors manage heat caused by long usage and are widely used in many lift brands.
DC Contactors
DC contactors are used for control circuits and door units in some elevator models. They provide stable performance and smooth switching and are preferred where low noise and controlled switching are required.
Bestech offers both AC and DC contactors so lift technicians can choose the right part for repair or system upgrades.
Signs That a Contactor Needs Replacement
Contactors work for a long time but show signs when they reach the end of their service life. Common signs include:
- Humming noise from the control panel
- Delay when the elevator starts
- Lift stopping briefly during startup
- Burn marks on the contactor body
- Loose or worn contact points
A weak contactor can damage the motor and other elevator control panel parts UAE, leading to higher repair costs.
Why Contactors Fail Over Time
Several factors reduce the lifespan of contactors:
- Heat generated from frequent use
- Dust buildup inside control panels
- Loose wiring connections
- Excess motor load
- Low-quality contact materials
This is why using quality contactors from a trusted elevator spare parts supplier UAE is important. It reduces risk and supports smooth lift movement. Bestech supplies contactors tested for UAE power levels to ensure long-lasting performance.
