Airless and Energy-Efficient Operation
Unlike conventional pneumatic tool changers, the Electric Auto Hand Changer operates without an air source. Once the tool is connected, no electric current is required, significantly reducing energy consumption and simplifying system design.
Simple Control and Slim Design
The system can be easily controlled using ON/OFF signals, eliminating the need for complex controllers. Its compact, slim structure minimizes interference with peripheral devices, making it suitable for space-constrained installations.
High Precision and Reliability
With a repeatability of ±0.003 mm [±0.0001 in.], the Electric Auto Hand Changer ensures accurate and stable tool positioning. This level of precision supports consistent quality and reliable automation performance.
Flexible Configurations for Various Applications
The product lineup supports maximum payloads of 3 kg, 10 kg, and 30 kg, accommodating a wide range of tools and applications. Multiple electrical interface options—including D-sub connectors, mini-connectors, solder terminals, and non-contact terminals—allow easy integration even in environments exposed to water or cutting fluid.
Supporting Productivity Improvement
By reducing downtime during tool changes and eliminating the need for air supply infrastructure, the Electric Auto Hand Changer helps manufacturers streamline operations and improve overall productivity.
