Overview

The LKP1AF-12V is a power relay used for applications that require up to 14 Amps. It works by using a magnetic field generated by current applied through the relay coil to move a ferromagnetic armature, which in turn will open or close the contacts of the contact assembly. The relay contacts can be used for electrical control of a variety of loads such as heating, lighting, pumps, motors and other devices. This power relay is available with a wide range of operating voltages and coil configurations.

Design Specifications

The LKP1AF-12V is designed with several features that make it useful in applications that require 14 Amps of current. The contact assembly is made of silver-nickel alloy, which provides a reliable electrical connection and high contact force. The contact gap is 0.4 millimeters, providing a reliable break time of less than 30 milliseconds. The mechanical life is rated for 100,000 operations and the electrical life for 10,000 operations. The operating temperature range is -20 to +85 degrees Celsius. The insulation system has dual insulation for reinforced protection.

Features and Benefits

The LKP1AF-12V is designed to provide reliable and safe operation in high-power applications. The contact gap is tight and consistent, minimizing the risk of contact bounce and arc erosion. The contact force is high to ensure reliable switching. The dual insulation system provides extra protection against the risk of fire and electric shock. The mechanical life of 100,000 operations means that the relay will last for many years. The operating temperature range of -20 to +85 degrees Celsius covers most industrial, automotive, and home applications.

Applications

The LKP1AF-12V is suitable for a wide variety of applications. It can be used in industrial control circuits, automotive applications, and home appliances. It is commonly used in applications such as heating, lighting, pumps, motors, and other loads requiring up to 14 Amps of power. The dual insulation system prevents against the risk of fire and electric shock. The high contact force ensures reliable, low-noise switching. The operating temperature range means it can be used in a variety of environments.

Working Principle

The LKP1AF-12V power relay works by using a magnetic field generated by current applied through the relay coil to move a ferromagnetic armature. The armature moves a set of contacts that open or close the contact assembly. When the current is switched off, the contacts will return to their original state. The mechanical and electrical life of the relay is long, providing reliable control of the contact assembly. The contact gap is 0.4 millimeters, providing quick break time under current load, and the contact force is high to ensure reliable switching.
