Crane limit switch SW2MS-LRL

for conveyorlargeanti-corrosion

Heavy-duty limit switch with an adjustable large roller lever designed for extreme and corrosive environments. Constructed from STS316L stainless steel for superior corrosion and salt resistance and engineered to withstand heavy mechanical stress.

Product features

• Robust construction with body and head in STS316L stainless steel, providing high resistance to corrosion and salt — suitable for marine and chemical gas environments.
• High mechanical strength absorbs irregular forces transmitted to the actuator, ensuring stable operation under heavy loads.
• Stable operational characteristics maintained over prolonged service life thanks to Qlight's proprietary dual-return spring system.
• External bolts, nuts and components in stainless steel (STS) to enhance corrosion resistance in polar and offshore conditions.
• Typical applications: overhead cranes, large conveyors, heavy industrial machinery, outdoor plants, ship deck machinery, port cargo handling equipment and chemical plants with corrosive acidic or alkaline gases.
• Optional low-temperature version (-40°C to +40°C) and high-temperature version (+50°C to +120°C) available on request.
