1、 Structural characteristics of APL310N valve limit switch box

APL310N valve limit switch box has become the first choice for many industrial users due to its sturdy shell design, high-precision internal switches, and rich configuration options. Its main structural features include:

1. Sturdy shell design: APL310N adopts a die cast aluminum alloy shell with a powder coating treatment on the surface, which not only has excellent corrosion resistance and wear resistance, but also ensures the beauty and durability of the product.

2. High precision internal switch: Equipped with 4 SPDT (single pole single double throw) mechanical limit switches, it can accurately detect the switch position of the valve, ensuring the accuracy and reliability of signal feedback.

3. Rich configuration options: APL310N provides various additional limit switches and wiring terminals to meet the needs of different users. The number of additional limit switches can reach 3-4, and the number of wiring terminals can reach 8-16, providing users with great flexibility.

4. Easy to identify switch position: The switch position can be clearly identified by the indicator, and users can quickly adjust the position of the switch cam without using tools, greatly improving the convenience of installation and maintenance.

5. Compliant interface: The dual line interface adopts dual 1/2NPT pipe interface (standard), and can also choose interface options such as M20, PG13.5, PF1/2 ", PT1/2", etc., to ensure compatibility with various valves.
