OverviewATI QC-21-E is a pneumatic robotic tool changer designed for fully automated end-effector exchange in high-cycle industrial environments. It provides secure locking with No-Touch actuation, integrated pneumatic passthroughs and high positional repeatability to support reliable robot uptime and fast tool changes.
Key features- (8) 1/8 BSPP / 1/8 NPT pneumatic pass-through ports in a compact 0.794 kg (1.75 lb) coupled package
- No-Touch locking technology allowing up to 2.03 mm (0.08 in) plate separation during locking
- Patented fail-safe locking mechanism minimizing force on the piston
- Supports multiple mounting patterns via interface plates; one flat provided for mounting utility modules
- Alignment features for torsional strength
- Optional Lock/Unlock sensors available
