Zeetork’s limit switch box services bridge the gap between actuator control and automated system feedback. Our core objective is to integrate and commission limit switch boxes into intelligent, high-performance automation solutions ready for operation. From accurate installation to thorough performance testing, we deliver reliable and industry-compliant switching solutions.
A limit switch box is an enclosure mounted on an actuator or valve that provides an electrical feedback signal to indicate the valve’s open or closed position. It helps operators or control systems monitor valve status remotely.
Its primary function is to send feedback signals (open/close or intermediate positions) to the control room or PLC and, in some cases, to display valve position locally through an indicator.
When the actuator moves the valve, a cam inside the box rotates, activating mechanical or proximity switches corresponding to the valve’s position. The switches then send electrical signals indicating whether the valve is open or closed.
It is typically mounted on top of pneumatic or electric actuators using a standard NAMUR or ISO 5211 mounting bracket, ensuring easy alignment with the actuator shaft.
| Feature | Mechanical Switch | Proximity Sensor |
|---|---|---|
| Contact Type | Physical (SPDT) | Non-contact (magnetic or inductive) |
| Durability | Moderate | Higher (no wear) |
| Application | Standard | Hazardous or corrosive |
| Signal Type | Discrete contact | Electronic signal |
Visual indicators (position domes) show the valve’s status at a glance.
