Snap action, limit switches are reliable electrical control components that amplify relatively small input signals and provide strong output signals. The AH745269-A is a high-performance snap action, limit switch that can be used in a variety of applications.

The AH745269-A is designed to detect the presence or absence of magnetic fields. The switch uses a reed contact that operates by a magnetic field. When a mechanical device is actuated, the closeness of a fluxing force causes a contact within the reed switch to move and the electrical circuit is then connected to make or break the connection. This variation in the magnetic field around the switch will cause the reed contact to make or break an electrical contact resulting in a on/off type output.

The AH745269-A can be used in applications such as industrial automation and equipment control circuits, medical device, security and safety circuit control, audio and radio equipment, toys and instrument control. The AH745269-A is particularly well-suited for any application where precise and repeatable actuation is critical, such as sensing the exact area for a hot water heater temperature control.

In addition to its primary use, the AH745269-A can also be used to detect the presence or absence of mechanical devices, such as motors and valves. The basic principle of operation is the same as with its magnetic sensing application. When the mechanical device is actuated, its movement will cause the reed contact to make or break an electrical connection. This electrical connection can then be used to control the operation of the mechanical device.

The AH745269-A has superior temperature, vibration and shock performance – temperature endurance up to 80°C (176°F) and vibration endurance up to 50G’s (500 Hz). The AH745269-A also offers two switch configurations for mounting and two product versions for plunger or lever actuation.

The AH745269-A utilizes an epoxy-coated glass-enclosed sealed contact and durable plastic housing, which is rated IP67 for dust tight and water resistant operation. The reed contact is also constructed with a special fluorocarbon resin that allows superior environmental resistance.

The AH745269-A can be used in a variety of applications and is an excellent choice for a wide range of control and automation applications. Its superior performance and reliable operation make the AH745269-A a great choice for any application requiring an efficient and reliable snap action, limit switch.
