Screw Fastening Counter

DLR5040A-WU

Features

Improves screw fastening accuracy by monitoring counts and torqued status

  • Ideally suited for assembly lines of vehicles and high volume equipment requiring accurate screw fastening
  • The controller receives status signals from the electric screwdrivers to provide details on screw status
  • Count return Function: When loosening a screw, a reverse signal is sent to the controller to reduce the count by one
  • Count Correction Function: Ignores counts on screws that are outside the preset parameters or double fastened
  • Driver Lock Function: Prevents unexpected startup of screwdrivers
  • Input voltage range of 100 V AC - 240 V AC for hassle-free installation
  • Link Connection: You can build up a simple sequential screw tightening system by connecting the DLR5040A screw tightening counters in series without using any external controller such as a programmable controller
  • 30 % smaller and 38 % lighter than our conventional models
  • Designed for SPC transformer-less screwdrivers
  • Grounded bit system standard

When counters are connected and activated in the screw fastening sequence as shown below, all screwdrivers are on standby except the first one in the sequence. Only when the first screw fastening is finished, can the next screwdriver change from standby to ready. When the last fastening in the sequence is finished, the first screwdriver is once again ready and the sequence can be repeated again.

Up to 10 screwdriver/counter sets can be connected to the LINK.

Acccessory
