feature

Corrosion-resistant
The shell of the APL410 Valve Limit Switch Box is made of die-cast aluminum alloy and sprayed with epoxy-polyester powder on the outside. It can withstand more than 720 hours of salt spray corrosion and is suitable for harsh environments such as seaside, high humidity, and strong corrosion.

High protection level
Relying on the precision sealing structure, the APL410 Valve Limit Switch Box provides IP67 standard and IP68 optional protection levels, effectively preventing water vapor, dust, or oil mist from entering the internal electrical components. In long-term immersion or spraying environments, the signal transmission can still be stable and reliable.

Reliable signal output
The APL410 is equipped with 2×SPDT mechanical limit switches, combined with an 8-position terminal block, which can simultaneously output switch signals of two independent circuits, enhance the redundancy and anti-interference of the control system, and improve operational safety and stability.

High visibility
The APL410 Valve Limit Switch Box is equipped with a highly visible dome indicator on the top, with a clear and intuitive red/yellow two-color display, which can easily identify the valve status at a distance of more than 5 meters.

Easy adjustment
With a spring-loaded cam mechanism, the APL410 Valve Limit Switch Box can achieve tool-free and quick adjustment of the limit points, significantly reducing installation and commissioning time.
