Snap Action, Limit Switches

The AHR5401619 is a snap-action, limit switch that is ideal for industrial applications, including automation and robotics, due to its robust design and ability to create an electrical connection when the switch is depressed. The switch has a single-pole double throw (SPDT) contact configuration, with one normally open (NO) and one normally closed (NC) contact. The life cycle of the switch is rated at one million operations, and the operating temperature range is -40°C to 80°C (-40°F to 176°F).

The AHR5401619’s robust design includes a coil spring that provides a return to its original position when the switch is released. The switch is also designed to be vibration resistant due to its rugged construction, which allows it to be used in industrial environments. Additionally, the high temperature plastic housing maintains its IP67 rating even when exposed to chemicals, oils, or high temperatures.

In order to use the AHR5401619, it must be connected to a circuit in order to complete the electrical connection. This requires connecting one end of the switch to a power or ground source, the other end of the switch to the circuit, and a return path from the circuit to the control source. For industrial applications, the input voltage for the switch should be 5 amps, and the output voltage should be no more than 240 VAC.

The AHR5401619’s working principle is based on a snap action mechanism in which a pusher bar is attached to an internal spring and when it is pushed, the switch is activated. The pusher bar\'s movement is controlled by a free motion lever that has been optimized to achieve consistent performance throughout its life cycle. When the switch is depressed, the free motion lever exercises its action on the pusher bar and the internal contacts open or close, depending on the configuration.

Once the switch is released, the return spring brings the free motion lever and the pusher bar back to the original position and the internal contacts return to the original state. The switch is designed to provide reliable performance even when subject to wear and tear, as the contacts are constructed from materials that are wear resistant and corrosion resistant.

The AHR5401619 is an economical, robust snap-action limit switch, designed for industrial and automation applications. Its SPDT contact configuration, wide operating temperature range and long life cycle make it an ideal choice for applications in which reliable switching is required. In addition, the switch is designed to be vibration resistant and its sealed plastic housing ensures an IP67 rating, making it suitable for applications in harsh industrial environments.
