44501-3520

Snap Action, Limit Switches

The 44501 series by Honeywell is a snap-action, limit switch which is designed to shut off, restart, or reverse the operation of a machine in response to physical contact, temperature, force and other pre-determined conditions. It is an electromechanical device that is used in many applications and is preferred because of its robust nature, reliable performance, and extended service life.

Application Field

The 44501-3520 snap-action, limit switch is most commonly used in machine safety systems, including automatic doors, industrial machinery, and other outdoor applications. Due to its robust design, it is also suitable for use in harsh and hazardous environments, such as mining and oil and gas industry applications.

Working Principle

The 44501-3520 snap-action, limit switch consists of several components that function together for the operation of the switch. It includes a body, a mechanical actuator, a contact system, and a set of terminals. The mechanical actuator is used to actuate the contact system which activates when it is exposed to predetermined conditions, such as pressure, force, or temperature. When activated, the contact system closes the circuit which can be used to shut off, restart, or reverse the operation of the machine.

The 44501-3520 snap-action, limit switch has a large number of contact arrangements, allowing it to be used in various applications such as simple on-off switching and controlled on-off switching. The contacts can be configured in either normally open (NO) or normally closed (NC) state.

The robust design allows the 44501-3520 snap-action, limit switch to be used in a variety of applications, from commercial and industrial applications to extreme operating environments. It is highly reliable and has an extended service life.

The 44501-3520 snap-action, limit switch is a reliable and robust electromechanical device that is used in many applications, and is an ideal choice for applications that require reliable operation in extreme conditions.
