V7-2A17D8-022

Snap action, limit switches are one of the most reliable, versatile and cost-effective sensors available and are used in a wide range of industrial applications. The V7-2A17D8-022 is a type of snap action limit switch and is used to detect the position or movement of a machine, triggering an alert or other action in response to its position or movement.

The V7-2A17D8-022 is a two-pole, three-position device, meaning that it has two poles that move independently and detect three different positions – normally opened (NO), normally closed (NC), and double-side normally opened (DSNO). The poles have a clear claw mechanism designed to provide an audible ‘click’ as the switch arms move from one position to the other.

The V7-2A17D8-022 has a voltage rating of 250V and a mechanical life of 50 million operations. The device also features an endurance of 10 million operations and a response time of 0.5 ms, making it a suitable choice for applications that require a fast reaction. The device has a temperature range of -10°C to +85°C and is IP40 rated for dust and water protection.

In terms of application fields, the V7-2A17D8-022 can be used in pneumatic machinery, machinery with limit valves and pumps, and automobile manufacturing machinery. The device excels in the detection of position and movement of a machine, triggering an alert and other functions in response to its position or movement. Examples involving the device include the monitoring of the position of a door where the switch can detect when the door is closed, as well as triggering an alert when the door is opened, or the detection of a machine’s cutting speed, where a slower speed triggers an alert.

In terms of working principle, the V7-2A17D8-022 works by having two electrical contacts attached to springs or other flexible arms that move in response to a mechanical force. The two contacts are electrically connected. When the device is triggered, the two contacts are either connected or disconnected, thus triggering a circuit which can then be used to perform an action, such as triggering an alert or changing the state of an electrical device. The device can also be used in a switch mode, allowing it to act as an on/off switch.

Overall, the V7-2A17D8-022 is a reliable yet cost-effective solution for the detection of movement and positioning of a machine. The device is suitable for a wide range of applications, including pneumatic machinery, machinery with limit valves, pumps and automobile manufacturing machinery. By having two separate electrical contacts with a flexible arm mechanism designed to provide a ‘click’ as the switch arms move from one position to the other, the device can be used to trigger an alert or other action in response to its position or movement.
