83720003

Application field

The 83720003 snap action limit switch provides a variety of features and flexibility for a wide range of applications including those related to automation, process and motion control, machine safeguarding, industrial equipment and robotics. These switches are used for activating or stopping a variety of motors, pumps, fans, valves, and other similar devices.

83720003 switches can also be used to detect potentially hazardous conditions and to shut down critical machinery or other dangerous equipment as a safety precaution against accidents. These switches are widely used in hazardous environments, since they are designed with enclosures that protect against dust, liquid and other contaminants.

Finally, 83720003 switches are often used in security systems to detect and control the opening or closure of a door or window, as well as in industrial safety applications to provide a control signal when hazardous conditions are present.

Working Principle

The 83720003 snap action limit switch is comprised of several basic components, including a hinge and actuator arm, a contact block, and a reset button. The hinge is designed to allow the actuator arm to move freely between two positions; the open and the closed. The contact block contains two moveable contacts; one normally open and one normally closed.

When the actuator arm is in the "open" position, both contacts will remain open, and the switch will be inactive. When the actuator arm is moved to the "closed" position, the normally open contact will be closed, and the switch will be activated. The reset button is used to reset the actuator arm to the "open" position after the switch has been activated.

The 83720003 snap action limit switch is designed to activate with a certain level of force, typically ranging from 0.5 to 5N and is designed to be able to handle a certain number of switch cycles, typically up to 100 million cycles. This is why it is called a "snap action" switch, as it is designed to quickly move between positions when the specified force level is applied.

83720003 switches are made to precise specifications and have a long operating life; they are generally capable of handling an average of up to 20 million cycles and are considered highly reliable. They are also designed to require a minimal amount of maintenance, making them ideal for a wide range of industrial, commercial and residential applications.
