APL-210N Limit Switch Box
The APL-210N limit switch box is designed for reliable valve position feedback in pneumatic actuator systems used in industrial automation. It provides clear open/close indication and electrical switching signals to support monitoring and control of quarter-turn valves such as ball valves and butterfly valves.
Mounted directly on the actuator, the device converts rotary valve movement into mechanical switching actions. These signals are typically sent to PLC or DCS systems, enabling accurate valve status confirmation in process control and safety interlocking applications.

Core Features
Housing Design and Environmental Protection: The enclosure is available in aluminum die-cast or stainless steel (304/316), depending on corrosion and durability requirements. Aluminum housing for general industrial service; stainless steel housing for corrosive or offshore environments. The IP67 protection rating ensures resistance against dust ingress and temporary water immersion, making it suitable for exposed field installations.
Mechanical Position Feedback System: The internal cam-driven mechanism provides direct actuation of mechanical switches based on valve rotation. Visual position indication: yellow for valve open, red for valve closed. This allows direct field verification of valve status without control system access.
Electrical Integration and Cable Entry: Supports multiple cable entry configurations for global installation compatibility: 2 x 1/2" NPT, PT1/2, PF1/2, M20, PG13.5. This flexibility supports integration into different regional standards and actuator control architectures.
