Crane limit switch SW2TS-RL

for conveyorlargeanti-corrosion

The SW2TS-RL is a heavy-duty roller lever limit switch designed for harsh industrial and marine environments. It combines STS316L stainless steel construction, configurable temperature variants and a proprietary dual-return spring system to deliver stable long-term operation across wide temperature ranges.

Product features

• Body and head made of STS316L stainless steel, providing corrosion and salt resistance suitable for marine and chemical gas environments
• Stable operational characteristics maintained after prolonged use via a proprietary dual-return spring system
• Stainless-steel external bolts, nuts, rollers and components for enhanced corrosion resistance in polar and offshore conditions
• Cold-resistant micro switches, low-temperature grease and silicone packing ensure reliable low-temperature performance
• Heavy-duty dimensions and mounting holes identical to standard switches for direct replacement
• Typical applications: overhead cranes; large conveyors; heavy industrial machinery; outdoor plant facilities; ship deck machinery; port cargo handling equipment; chemical plants with corrosive acidic or alkaline gases
• Available variants: Cold-Resistant Type (-40°C to +40°C) and Heat-Resistant Type (+50°C to +120°C)
