Options of Torque Limiters TT(01) Types
Optional Signal Pin
Unattended or remotely controlled machines and equipment require equipment that detects an overload and automatically switches off the power or sounds a warning alarm.
An overload can be detected by connecting the signal pin to the torque tender.
When an overload is detected, the input side and the output side are disconnected and the cam mechanism of the torque tender hub pushes the signal pin out in the radial direction. This can be used to switch off the power or sound a warning alarm.
Be sure to use the housing as the input side.
The standard product cannot be modified to connect the signal pin. If you need to
connect the signal pin, add "-P" to the end of the model when you order the product.
