OverviewThe SW2TS-AL is an adjustable roller lever limit switch engineered for heavy-duty industrial use in harsh and corrosive environments. Constructed mainly from STS316L stainless steel and designed for long-term stable operation, it is suitable for marine, offshore and chemical plant applications.
Key features- Body and head made of STS316L stainless steel for enhanced corrosion and salt resistance, ideal for marine and aggressive-gas environments.
- Proprietary dual-return spring system providing consistent actuation characteristics over prolonged service life.
- All external bolts, nuts and components in stainless steel to resist corrosion in polar and offshore conditions.
- Cold-resistant micro switches, low-temperature grease and silicone packing available for reliable operation at very low temperatures.
- Heavy-duty mechanical design with dimensions and mounting holes compatible with standard switch footprints.
- Adjustable roller lever actuation for flexible installation and detection angles.
Applications- Overhead cranes, large conveyors and heavy industrial machinery requiring reliable position detection.
- Outdoor plant equipment, ship deck machinery and port cargo handling systems.
- Chemical processing plants where acidic or alkaline corrosive gases are present.
