About Pull wire limit switches (Traction operation)

Pull wire limit switches

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.

Superior Safety and Reliability

Engineered with a 1NO+1NC snap action contact arrangement and silver alloy contacts, the Pull Wire Limit Switch guarantees rapid response and dependable performance during emergency stops. Its manual reset function ensures deliberate startup procedures, minimizing accidental restarts and increasing workplace safety.

Built for Industrial Environments

Housed in a reinforced glass fiber polyamide body with zinc-plated components, this switch withstands challenging industrial settings. Boasting an IP65 ingress rating, high shock (30G) and vibration resistance (10-55Hz, 1.5mm), it is ideal for harsh environments without sacrificing operational integrity.

Flexible Mounting and Easy Maintenance

Designed for surface mounting with a convenient four-point system, the switch accommodates a wide range of installation setups. Screw-type terminals for up to 2.5mm2 conductors simplify wiring, while straightforward manual reset makes maintenance both easy and secure.

FAQ's of Pull wire limit switches (Traction operation):

Q: How does the pull wire limit switch operate during an emergency?

A: During an emergency, pulling the attached steel wire (pull cord) actuates the switch. The internal snap action mechanism instantly changes the status of the contacts (1NO+1NC), triggering an immediate response to shut down, stop, or control connected systems for enhanced safety.

Q: What environments are suitable for installing this pull wire limit switch?

A: The switch is suitable for industrial settings requiring robust safety controls. Its IP65 rating, reinforced polyamide body, and resistance to shock and vibration make it ideal for harsh or dusty areas, including manufacturing lines and automated machinery environments.

Q: When is it necessary to manually reset the switch?

A: A manual reset is required after every actuation. This ensures intentional reactivation, preventing accidental restarts and improving operational safety by allowing personnel to assess the situation before system restart.

Q: Where should the device be mounted for optimal performance?

A: For best results, the switch should be surface-mounted using the designated four-point system at accessible locations along conveyor lines, processing machinery, or other equipment requiring emergency shutoff. Proper placement allows quick access in critical situations.

Q: What is the process for connecting wires to the switch?

A: Wires are connected via the screw-type terminals provided, accommodating conductors up to 2.5mm2 in size. Ensure the cable enters through the M20 x 1.5 entry and tighten the terminals securely for reliable operation and safety compliance.

Q: What are the benefits of using a snap action, manual reset limit switch in industrial automation?

A: The snap action mechanism ensures instantaneous and reliable signal transmission for safety-interlock applications. With manual reset, it prevents accidental system restarts, promoting deliberate and secure corrective actions, reducing downtime and enhancing productivity.
