Robust Design for Industrial EnvironmentsConstructed from die-cast aluminum alloy and finished with powder coating, this switch withstands harsh settings in automation, cranes, and hoists. The IP65 protection ensures reliable performance in dusty or humid environments, while the ambient humidity resistance (85% RH) makes it suitable for varied industrial climates.
Flexible Operation and Adjustable SettingsThe limit switch provides flexible control with adjustable lever stroke up to 50mm and both 1NO+1NC or 2NO+2NC contact configurations. Snap action circuits ensure fast response (15 ms), ideal for precise automation sequences. Surface mount installation and screw terminals simplify setup and maintenance.
Certified Safety and Long LifeComplying with IEC 60947-5-1, the switch guarantees industry-standard safety and longevity. With insulation resistance 100 M (at 500V DC), shock resistance up to 30g, and a mechanical life exceeding 10 million operations, its a cost-effective, dependable solution for any application requiring accurate position feedback.
FAQs of Variable Limit Switch:
Q: How is the variable limit switch used in industrial automation and lifting applications?
A: The variable limit switch is commonly installed on hoists, cranes, and automated machinery to provide position detection and stop control. When the actuators adjustable lever arm reaches a preset position, it quickly opens or closes the configured contacts, sending a signal to control panels or machinery for operational safety and automation.
Q: What benefits does the adjustable lever arm offer?
A: The adjustable lever arm allows users to set the switching point anywhere within a 50 mm stroke, enhancing flexibility for different application requirements. This adaptability minimizes installation adjustments and maximizes compatibility with various movement ranges in machinery.
Q: When should the contact configuration be set to 1NO+1NC versus 2NO+2NC?
A: Choose 1NO+1NC when you need a single normally open and a single normally closed contact for simpler control circuits. Opt for 2NO+2NC if your application requires additional feedback or dual-circuit redundancy for enhanced safety and control flexibility.
Q: Where can this limit switch be installed, considering its environmental ratings?
A: Thanks to its IP65 protection, shock resistance, and vibration tolerance, the limit switch can be installed in both indoor and outdoor industrial settings where humidity is 85% RH and temperatures range from -20C to +70C, including crane gantries, conveyor systems, and automated production lines.
Q: What is the process for wiring and mounting this limit switch?
A: Mount the switch on a flat surface using the provided holes. Insert cables through the 2 x PG13.5 cable entries and connect them to the internal screw terminal block. Ensure wiring complies with the switchs voltage and current ratings (max 500V AC, 10A) and follow IEC 60947-5-1 standards for safety.
Q: What advantages are offered by the die-cast aluminum alloy body and powder-coated finish?
A: The robust die-cast aluminum body provides high durability against impacts and corrosion, while the powder-coated finish enhances resistance to harsh environmental elements and increases the products lifespan, making it ideal for industrial sites.
Q: Who can benefit from distributing or supplying this limit switch in India?
A: Dealers, distributors, exporters, manufacturers, producers, retailers, service providers, suppliers, traders, and wholesalers can successfully cater to the industrial automation sector in India by offering this certified, reliable, and easy-to-install limit switch for diverse machinery applications.
