LIMIT SWITCH
FUKUOKA
The LIMIT SWITCH LWIO-SA1 is a robust marine-grade position detection switch designed for monitoring the movement and end-position status of mechanical equipment onboard ships and offshore installations. Manufactured by Sakamoto Electric Manufacturing Co., Japan, the LWIO-SA1 is widely used in marine automation systems, deck machinery, cargo handling equipment, hatch covers, cranes, valves, and various motion-control applications.
Based on the supplied image, the equipment is clearly identified as a LIMIT SWITCH Type LWIO-SA1, featuring a roller-actuated lever mechanism housed within a rugged industrial enclosure. The unit is specifically designed to provide reliable switching signals whenever moving equipment reaches a predefined position.
Marine automation systems depend heavily on accurate position feedback to ensure safe operation, prevent mechanical damage, and support automatic control sequences. The LWIO-SA1 plays a critical role in these applications.
The LWIO-SA1 Limit Switch is designed to detect the movement or final position of mechanical components. When the roller arm comes into contact with a moving object, the switch mechanism changes state and generates an electrical signal that can be used by monitoring systems, PLCs, relays, automation controllers, or safety circuits.
The rugged housing protects internal contacts from harsh marine environments, while the roller lever design ensures smooth operation and reliable actuation.
This type of limit switch is commonly installed on hatch covers, cargo cranes, winches, davits, watertight doors, valves, steering gear systems, cargo handling equipment, and automated machinery where precise position monitoring is required.
The compact design, proven durability, and long operational life make the LWIO-SA1 a trusted solution for marine automation applications.
The LWIO-SA1 provides accurate and dependable position feedback for moving equipment and mechanical systems.
The roller actuator minimizes wear and ensures smooth contact with moving machinery components.
Designed for marine environments, the switch withstands vibration, humidity, temperature variations, and continuous operation.
Industrial-grade contact mechanisms ensure consistent switching performance and long service life.
The switch supports equipment protection by detecting travel limits and preventing over-travel conditions.
The LWIO-SA1 can be integrated into PLC systems, automation controllers, relay circuits, alarm systems, and machinery control networks.
Its compact enclosure simplifies installation while maintaining excellent mechanical protection.
