Tohnichi CNA-4MK3 Poka Patrol Count Checker

Overview

Count checker to prevent missed tightening.
Can be connected to LS (Limit Switch) torque wrenches for count management.
Up to four LS torque wrenches can be connected, and each can be set with a different number of bolts to tighten. So up to four operators can perform tightening tasks at the same time.
From one unit, the numbers of four different types of bolts to be tightened can be set.
Bolt counting can be set 0-99 pcs for each torque wrench, and count down upon receiving a signal.
OK/NG judgement signal can be transferred to external device through relay output.
Connected with LS type torque wrenches (sold separately), CNA4-mk3 establishes error-proofing system.
