Application

Pokayoke (tightening assurance).

Features

Adjustable style torque wrench with limit switch output.
Upon reaching the set torque, the torque wrench "clicks" to complete tightening while the limit switch simultaneously sends out a contact signal.
A limit switch can be connected to a CNA-4mk3 count checker (sold separately) to easily create a tightening count management system.
Signals from a limit switch are captured on a programmable logic controller (PLC) or similar device to establish a Tightening Assurance System using assembly line interlock controls.
LS wrenches are supplied with a durable curl cord.
