Crane limit switch SW2TS-LRL

for conveyorlargeanti-corrosion

Overview

Adjustable heavy-duty large roller lever limit switch SW2TS-LRL designed for corrosive, marine and extreme-temperature environments. Constructed primarily in STS316L stainless steel with stainless external components for long-term stable operation and enhanced corrosion resistance.

Key features

• Robust construction: body and head made of STS316L stainless steel for high corrosion and salt resistance, suitable for marine and chemical gas environments
• Stable operation maintained after prolonged use via a proprietary dual-return spring system
• External bolts, nuts and components in stainless steel to resist corrosive offshore and polar conditions
• Reliable performance in low temperatures using cold-resistant micro-switches, low-temperature grease and silicone packing
• Heavy-duty dimensions and mounting holes identical to standard switches for straightforward replacement
• Typical applications: overhead cranes, large conveyors, heavy industrial machinery, outdoor plants, ship deck machinery, port cargo handling, chemical plants with acidic or alkaline corrosive gases
• Custom temperature variants available on request: Cold-Resistant Type (-40°C to +40°C) and Heat-Resistant Type (+50°C to +120°C)
