.A1223LLHLX-T magnetic sensor switches are designed for applications where a low-reliability, part-time switch operated by a magnetic field is a viable solution. They are ideally used for applications such as contactless keyless entry systems, security systems, access control, level sensing and other industrial process control. This type of magnetically activated switch is a solid-state device that uses the power of magnetism to detect objects without moving parts.
The A1223LLHLX-T sensor switch is specifically designed to offer a low profile, reliable and repeatable limit switch requiring no contact with any moving parts. This switch is constructed from a solid ceramics body with an aluminum coil element. It is a single pole, single throw switch that closes when a magnet is detected.
The working principle of the A1223LLHLX-T sensor switch is based on the principle of magnetic field flux. When a magnet is passed near the switching position of the switch, the resulting magnetic field induces current within the coil element, which triggers the switch to close. This closing action results in an electrical signal being sent. The current produced in the aluminum coil element creates a self-energizing mechanism, which provides an increased response to the magnet.
The A1223LLHLX-T switch is ideal for many applications requiring a low-reliability, part-time switch. It is designed for use in lighting, weighing scales, vending machines, robotics, security systems, access control, and industrial process control. Some of the benefits of this type of magnetically activated switch include: no need for physical contact, prolonged operating life of over 100 million cycles, low power requirements, low cost, and no maintenance.
In conclusion, the A1223LLHLX-T magnetic sensor switch is a reliable, low profile and low cost switch specifically designed for applications requiring a reliable and repeatable limit switch. It utilizes a self-energizing mechanism to respond reliably to a passing magnetic field, and can withstand over 100 million cycles of operation. This type of switch is ideal for applications in lighting, weighing scales, vending machines, robotics, security systems, process control, and access control.
