The RS-8112A Automatic Abrupt Pull Tester is designed for durability testing of power cords, charging cables, headphone wires and connector assemblies. It delivers repeatable abrupt pull testing with programmable cycles, automatic failure detection and servo-driven precision for laboratory and production quality control.
The RS-8112A Automatic Abrupt Pull Tester is designed to evaluate the mechanical durability of cables and connector assemblies by simulating repeated abrupt pulling forces that occur during everyday use, transportation and handling.
Using a programmable servo-driven lifting system and a calibrated test weight, the tester repeatedly applies a controlled pulling force to the specimen, allowing manufacturers to verify connector retention, cable strength and assembly reliability under consistent testing conditions.
The system operates automatically after parameter setup, reducing operator involvement while ensuring excellent repeatability throughout long-duration tests. Automatic failure detection, high positioning accuracy and industrial-grade control components make the RS-8112A suitable for both product development and routine quality inspection.
2. Setting test cycles of needed abrupt pull in the touch screen, for example, 200 cycles. When reaching set test cycles, it will stop testing automatically.
3. Pressing test key; pneumatic fixture clamps the dedicated weight; electric cylinder drives the weight to rise 150mm; pneumatic clamp immediately loosens; abrupt drop of weight leads to abrupt pull test on cable; pneumatic fixture clamps dedicated weight; electric cylinder drives dedicated weight to rise the cycle repeats until it finishes set test cycles.
4. The main unit is designed with optoelectronic switch, so if the cable is snapped in the test and resulting in weight dropping to the baseboard, the machine will automatically stop testing with audible and visible alarm.
Fully Automatic Test Operation
After the test parameters are configured, the complete test sequence is performed automatically. The system repeats the programmed abrupt pull cycle until the preset number of cycles is reached or the specimen fails, improving testing efficiency while minimizing operator intervention.
High-Precision Servo Motion System
The lifting mechanism is driven by a Panasonic AC servo motor and precision electric actuator, providing stable motion control and positioning accuracy of ±0.02 mm. This ensures excellent repeatability between test cycles and improves the consistency of evaluation results.
Flexible Parameter Programming
Test parameters can be adjusted through the OMRON touch-screen interface according to different product requirements, including:
This flexibility allows the tester to accommodate different cable types and internal testing specifications.
Automatic Failure Detection
A built-in photoelectric detection system continuously monitors the specimen during testing. If the cable breaks or separates from the connector, the machine immediately stops and activates both audible and visual alarms, helping protect the equipment while preventing unnecessary test continuation.
Reliable Industrial Components
The RS-8112A incorporates high-quality components from internationally recognized manufacturers, including Panasonic servo systems, Mitsubishi PLC, OMRON touch screen, SMC pneumatic components and AIM electric actuators to ensure stable operation and long service life.
Safe Enclosed Design
The rigid aluminum alloy frame combined with transparent protective panels provides a clear view of the testing process while improving operator safety during continuous operation.
