Conveyor limit switch SW2MS-AL

anti-corrosionIP67chemical-resistant

The SW2MS-AL is an adjustable roller lever limit switch designed for corrosive and harsh industrial environments. It uses STS316L stainless steel construction and an engineered mechanical design for long-term stable operation.

Key features

• STS316L stainless steel body and head for high corrosion and salt resistance, suitable for marine and chemical gas environments.
• External bolts, nuts and components made of stainless steel for enhanced corrosion resistance in polar and offshore conditions.
• High mechanical strength to absorb irregular motions transmitted to the actuator and improve operational stability.
• Proprietary dual-return spring system to maintain consistent operating characteristics after prolonged use.
• Adjustable roller lever actuator type.
• Optional temperature variants on request: Cold-Resistant Type (-40°C to +40°C) and Heat-Resistant Type (+50°C to +120°C).

Typical applications

• Overhead cranes and large-scale conveyors.
• Heavy industrial machinery and outdoor plant facilities.
• Ship deck machinery and port cargo handling equipment.
• Chemical plants handling corrosive acidic or alkaline gases.
