Magnetic Sensors and Switches (Solid State) in particular is a technology which has drastically changed in recent years, from traditional mechanical switches which respond to changes in magnetic field strength, to Solid-state electronic components which react in a range of ways to changes in magnetic field strength. The AH1810-W-7 is a Solid State Magnetic switch, and it has many advantages over its mechanical predecessor. In this article, we will look at the application field and working principle of the AH1810-W-7.

Application Field

The AH1810-W-7 Magnetic Switch is a popular choice for a wide range of applications. It is especially suited for applications where the position of a load must be accurately monitored in a space-constrained environment. This could be a pipeline checking valve for pressure or flow, a door or window position detector, or even a component of a pipeline pressure relief valve control system. The Magnetic switch is also a popular choice for applications which require a high resistance to corrosion or high temperatures, as its metal case and integrated solder pads provide a high degree of protection. The application fields of the AH1810-W-7 include but are not limited to:

• Monitor Valves in Pipelines
• Pressure Relief Valves
• Flow Control Valves
• High-Temperature Sensors
• High-Resistance Corrosion Sensors

Working Principle

The AH1810-W-7 magnetic switch is essentially a contact-less reed-switch, designed to respond to a change in the magnetic field of a nearby magnet. When a magnet is brought close to the switch, the motion of the magnet causes a force to be exerted on the metal wire within the switch. The wire then moves, closing a contact in the switch and completing the circuit. The switch is able to detect movement both in the x-axis and y-axis, as well as be set to either a Normally Open (NO) or Normally Closed (NC) configuration. This is achieved with an integrated logic board which measures the intensity of the magnetic field and the presence of any nearby magnets.

The AH1810-W-7 magnetic switch is designed to be used with any type of permanent magnet. This flexibility allows the switch to be used in a variety of applications. The switch is able to detect magnets with up to 10mm of air gap, and the presence of a magnet is indicated by a voltage change on the two sensitive wires of the switch. For further information on the working principle of the AH1810-W-7, please refer to the product manual or contact a Corintech sales representative.

Conclusion

The AH1810-W-7 is a Solid-state Magnetic switch which has many advantages over its mechanical predecessor. It is able to detect movement in two dimensions, has a flexible range of applications, and is able to detect magnets with up to 10mm of air gap. The integrated logic board allows the switch to be set to either a normally open or normally closed configuration. With a rugged all-metal case, the AH1810-W-7 is a durable alternative to traditional mechanical switches.
