D2SW-P2L2B

Snap action, limit switches are widely used in contactless-sensing construction applications, ranging from industrial automation to medical science.

D2SW-P2L2B is a cost-effective and reliable type of contactless-sensing snap action, limit switch, which can reliably detect and control various types of application material. It is designed for applications such as micro-machining and/or manufacturing, specifically for measuring rotational positions in low speed/high precision applications.

In terms of application field, D2SW-P2L2B snap action, limit switch has a wide range of applications, such as automotive, electronic device, medical equipment, aerospace and industrial automation fields. It is used for security protection of reverse travelling, rotational position detecting and machine controlling.

In terms of working principle, the D2SW-P2L2B snap action, limit switch is based on a Hall-effect principle. It consists of two detecting elements – a permanent magnet and a Hall-effect sensor – which are placed as an assembly on a swing arm. When the swing arm is displaced due to the action of a target, its magnetism field moves in the same direction. The Hall-effect sensor senses the changes in the magnetism field and changes its output appropriately. Once a predefined threshold is reached, the output of the Hall-effect sensor is changed, triggering the action of the switch.

D2SW-P2L2B snap action, limit switch is a reliable, low-cost alternative to the expensive optical and mechanical limit switches traditionally used in many applications. Its accurate and reliable performance ensures predictable switching action that prevents misoperation or slipping. The Hall-effect principle used in the D2SW-P2L2B snap action, limit switch guarantees optimal performance, making it ideal for applications where high precision is required, even in harsh environments.

In conclusion, the D2SW-P2L2B snap action, limit switch is a reliable solution for contactless-sensing applications, offering a cost-effective alternative to cheaper optical and mechanical limit switches. Its precision, reliability and accuracy give it an advantage over other alternative switches and make it a suitable choice for applications where high precision and reliability is required.
