AH71556559-A

Snap action, limit switches, like the AH71556559-A, are electromechanical devices designed to switch electrical circuits in response to a given set of conditions. This particular switch is a single-pole, double-throw type with a narrow operating range.

The AH71556559-A’s primary function is to detect the presence or absence of a physical contact between two objects. When the contact is made or broken, the current flow in the electrical circuit is changed, causing the switch to open or close. This is known as a snap-action switch, because the switch will “snap” open or closed when the contact is made or broken.

The AH71556559-A’s typical application field is in the industrial control field, where the availability of a reliable limit switch is a key element for the correct and efficient functioning of automated machinery. It is a valuable tool for monitoring the positions of pieces of machinery, and can be used to control both machinery and processes. It is also used in applications such as digital counters, level detectors, proximity sensors, and automatic door openers.

The working principle of the AH71556559-A is based on a simple mechanism. The switch is made up of two contact arms, each of which contains a spring-loaded sensor. When the contact arms are closed, the circuit is complete and the switch is in the closed position. When the contact arms are opened, the circuit is broken and the switch moves to the open position.

The switch can be mounted in any position, and it is capable of operating in temperatures ranging from -40°C to +85°C. The contact ratings of the switch are based on both ambient temperature and current, and vary from 2A at 250VAC to 5A at 250VAC. The contact resistance of the device is typically 1.4~4.4 milliohms, and the dielectric strength of the switch is 500 VAC at 1 minute.

In summary, the AH71556559-A is a reliable and rugged snap-action limit switch designed for industrial control applications. It is designed for long life and easy maintenance, and is capable of operating in extreme temperatures. The switch is simple to mount, and its contact ratings, contact resistance, and dielectric strength make it suitable for a wide variety of industrial applications.
