Prevent forgetting to tighten screws! 'Screw Star σ'

Counter for discovering and preventing forgotten tightening of screws (careless mistakes)

● This is a control device designed to be used in combination with an electric screwdriver to detect and prevent "forgotten screw tightening (human error)" and "incomplete screw tightening." ● It automatically measures the screw tightening time, making it easy to set up. (Manual settings allow for precise adjustments.) ● With the second timer setting, it can stop the screwdriver's rotation. (It alerts you when a long screw is mistakenly tightened.) ● It can memorize eight different screw tightening patterns and perform screw tightening by combining them sequentially. ● It is equipped with various I/O terminals, allowing for connection with automated machines. ● Even if multiple screwdrivers are used, you can increase the number of units through a daisy chain and control the screwdrivers in the order of operation. * For more details, please refer to the catalog. For inquiries, please contact Koyama Co., Ltd.
