Pull wire limit switches a Operation only in traction
Limit switches with rope for simple stop, without manual reset. These limit switches are useful for signalling and for commanding doors or similars. Available also in special version with double signal in traction or release, helpful to signal an eventual loss of tension due to the breaking of the rope.
Designed for Safety and DurabilityThis emergency pull wire limit switch is optimized for conveyor belt systems, delivering reliable performance and user safety. Its thermoplastic enclosure paired with a metal lever withstands demanding industrial environments, offering over a million mechanical actuations. The switch's wire tension release mechanism ensures secure operation in emergency situations.
Compliance and Industrial ApplicationAdhering to EN 60947-5-1 standards, this limit switch is fit for industrial grade automation. It handles up to 250V AC and 6A, making it suitable for high-demand conveyor applications. The IP65-rated enclosure and high vibration resistance allow for operation in challenging conditions with ambient humidity up to 95% RH.
FAQ's of Pull wire limit switches a Operation only in traction:
Q: How does the manual reset function work on this pull wire limit switch?
A: After activation, the manual reset ensures that the switch remains in the stop position until an authorized operator physically resets it. This feature enhances safety by preventing accidental or unauthorized system restarts.
Q: What applications are suitable for this pull wire limit switch?
A: This limit switch is ideal for use as an emergency stop device on conveyor belt systems in industrial settings, thanks to its robust design, compliance with EN 60947-5-1, and IP65 ingress protection.
Q: When should I consider using a pull wire limit switch instead of standard emergency stop buttons?
A: A pull wire limit switch is recommended when you need emergency stopping capabilities over long distances (up to 50m), such as along conveyor belts, offering quick access from any point along the line.
Q: Where can the switch be mounted for optimal performance?
A: This device is designed for surface mounting on machinery or support structures along the sides of conveyor belts, ensuring accessibility and effective emergency response.
Q: What is the process for replacing the steel wire actuator?
A: To replace the steel wire actuator, first disconnect power. Release the wire tension and detach the existing wire. Attach the new steel wire, adjust tension according to the installation guide, and confirm reliable operation before resuming use.
Q: What benefits does the snap action changeover contact provide?
A: The snap action design ensures reliable and instantaneous switching, minimizing the risk of contact welding or incomplete circuit interruption even during high-speed or heavy-load operations.
