About Limit switches for over-speed devices
Limit switches for over-speed devices
Switches specifically designed for applications on over-speed devices. By actuating the plunger until the operation position P1, the electrical contacts switch and simultaneously the plunger reaches automatically P2 position. The device is restored by pulling the blue plunger until P0 free position.

FAQ's of Limit switches for over-speed devices:
Q: How can I install the limit switch for over-speed applications?
A: Installation is simplified via screw terminal connections and horizontal alignment. It's suitable for panel or surface mounting, with clear dimensions of 86 mm x 40 mm x 38 mm. The process involves securing the switch, connecting wires as per the terminal diagram, and ensuring the actuator is properly aligned with the moving part.
Q: What are the benefits of IP67 certification for this switch?
A: IP67 ingress protection ensures the device is fully dust-tight and can withstand immersion in up to one meter of water for 30 minutes. This is particularly beneficial in industrial environments with frequent dust and splashing, guaranteeing long-term reliability.
Q: When should I use this over-speed limit switch in my automation system?
A: This switch is ideal for installations requiring high-frequency actuation, precise over-speed monitoring, and robust environmental resistance. Typical use cases include conveyor systems, industrial machinery, and safety interlocks where over-speed can pose risks.
Q: Where is this limit switch commonly utilized?
A: Due to its durable construction and advanced protective ratings, the switch finds application in factories, processing plants, and automation setups. It's supplied, exported, and distributed globally, including Italy, through established suppliers and traders.
Q: What is the process for wiring the limit switch?
A: Wiring involves connecting to screw terminals with silver-plated contacts arranged in a single-pole double-throw (SPDT) configuration-1 NO and 1 NC-using standard panel-mounting procedures to integrate into control circuits for automatic response to over-speed conditions.
Q: How does the actuator type and switching frequency affect its usage?
A: The plunger actuator provides accurate position sensing with a stroke of 15 mm and supports 120 operations per minute. This makes the switch highly effective for continuous operation and rapid cycling in automated systems.
