AVAILABLE FUNCTION SYSTEMS OF R+W TORQUE LIMITERS AND SAFETY COUPLINGS

Single-position re-engagement

Properties of single-position Torque Limiters (standart version):

• After the overload has been removed, the safety coupling will re-engage precisely 360° from the original disengagement position.
• Signal at overload.
• Suitable for use in machine tools, packaging machinery, automation systems and other applications requiring precise timing.

Multi-position re-engagement

Properties of multi-position Torque Limiters:

• Coupling re-engages at multiple set angular intervals.
• Immediate availability of the machine as soon as the overload has been removed.
• Signal at overload with mechanical switch or proximity sensor.
• Standard engagement after 60°.
• Engagement after 30, 45, 90 and 120 degrees optional.

Load holding version

Properties of load holding Torque Limiters:

• Mechanical overload detection device.
• In the event of an overload, the drive and the driven elements are not fully separated and are only allowed limited rotation.
• Guranteed to hold the load and signal an overload.
• Automatic engagement after the torque level has dropped.
• Signal at overload to detect with mechanical switch or proximity sensor.
• Suitable for use on presses, load lifting equipment and where the drive and driven elements can not be separated.

Full disengagement version

Properties of full disengagement Torque Limiters:

• Permanent separation of driven and driven elements in the event of an overload.
• No residual friction.
• Signal at overload with mechanical switch or proximity sensor.
• Rotating elements slow down freely.
• Coupling can be re-engaged manually (Engagement every 60°); other engagements available.
• For use in high speed applications.

Indication: Safety Coupling can be disengaged manually. Please contact R+W.
