Multi-purpose Contacts, such as the model 66394-7, are becoming more popular as solutions to complex switching applications. The sensor is designed to perform multiple contacts simultaneously and is available in both normally open and normally closed configuration. This article will explain the application field and working principle of model 66394-7.

Applications

Model 66394-7 is suitable for a wide range of applications and can be used in both commercial and industrial settings. It is well-suited for detecting small objects, such as coins or other metallic objects, and is effective for counting applications. Additionally, it can be used as a proximity switch when combined with spring-mounted actuators. It can also be used for liquid level control and can measure the pressure, flow and temperature in a number of applications. It can be used to detect foreign particles in fluids, such as oil or gas, as well as for valve position verification.

Working Principle

The 66394-7 contact works by applying a magnetic field to an external device, such as a metallic object or a spring-mounted actuator. When the external device approaches the contact, it induces a magnetic field in the contact that is detected by a small coil. The coil then triggers a switch inside the contact, which will act according to the polarity of the device. The switch is typically set in either a normally open or normally closed configuration.

The 66394-7 can be used in a wide variety of applications. By using the contact in combination with an external device, a wide array of configurations and applications can be achieved. It is an ideal solution for counting and measuring applications as well as for liquid level control and foreign particle detection.
