ITM-LAB - Model RS-DP-12A -Rolling Angle Drop Tester

SHARE

The RS-DP-12A Rolling Angle Drop Tester performs continuous rotation (rolling drop) tests for portable electronic products to verify impact resistance and structural reliability during daily use and transportation. The ITM-LAB RS-DP-12A Auto Tumble Tester is a high-precision reliability evaluation system engineered to simulate repetitive, chaotic rolling impacts experienced by small portable electronics during real-world handling and transit. Featuring a rugged dual-height drum structure, advanced AC servo motor mechanics, and intelligent PLC synchronization, the system provides high repeatability for testing product housing durability, internal assembly stability, and long-term functional retention in strict compliance with global quality standards.

  • AC Servo Motor Precision:

Features a premium AC servo drive that locks the drum at any precise angle instantly. This allows engineering teams to pause execution and inspect specimen damage mid-cycle without resetting the system.

  • Industrial-Grade Chassis:

Constructed with heavy-duty 3mm thick structural steel plates and an anodized aluminum alloy frame to completely eliminate body vibration and dampening errors.

  • Standard-Compliant Striking Bed:

Built with a 17–19mm premium wood substrate faced with a 3mm rigid steel plate, fully satisfying international regulatory laboratory criteria.

  • Smart PLC Architecture:

Integrates a 7-inch Omron color touchscreen with a Mitsubishi PLC core for intuitive, programmable cycle counts and real-time speed tracking.

  • Fail-Safe Door Interlocking:

Equipped with an automated electronic safety lock that instantly cuts off motor power the moment the enclosure door is opened during a live test run.

  • Mobile Communication Devices: Smartphones, tablets, e-readers, and feature phones.
  • Wearables & Acoustics: Bluetooth earphones, headsets, portable media players (CD/MP3/MP4), and smart wearables.
  • Precision Electronics & Accessories: Remote controllers, connectors, walkie-talkies, and electronic dictionaries.
