WEATHER PROOF PROXIMITY LIMIT SWITCH
“aline” Make Weather Proof Proximity Limit Switch is a high-performance valve position monitoring device designed to provide accurate and reliable OPEN/CLOSE position feedback for pneumatic and electric actuated valves. Equipped with non-contact proximity sensors, it eliminates mechanical wear, ensuring longer service life, higher switching accuracy, and maintenance-free operation in demanding industrial environments.
Manufactured with a rugged die-cast aluminium weatherproof enclosure and high-visibility visual position indicator, the ALINE Proximity Limit Switch is ideal for Ball Valves, Butterfly Valves, Plug Valves, Dampers, and other quarter-turn actuators. Its compact design, excellent environmental protection, and compatibility with NAMUR and VDI/VDE 3845 mounting standards allow easy installation on most pneumatic and electric actuators.
Designed for reliable performance in outdoor and harsh industrial conditions, the ALINE Weather Proof Proximity Limit Switch is widely used in Water Treatment, Chemical, Petrochemical, Oil & Gas, Pharmaceutical, Food Processing, Marine, Power Plants, Steel, Cement, Paper, and General Industrial Automation applications.
