Download ETCO's Locking Ring Terminal Evaluation TechNote

ETCO R&D designed a locking ring terminal to support ground connections on steel appliance framings. The new terminal style also features tangs that dig deeper into the surface finish for better grounding. In a series of tests – including crimp cross sections, terminal torque retention to surface measurements, and more – ETCO’s locking ring terminals were superior to competitors’ in:

  • Retention measurements in both pull directions
  • Terminal penetration
  • Electrical test performance

ETCO's Ring Terminals Are Perfect for Small Ignition Coils

Small but strong, ETCO’s versatile ring terminals withstand the test of time.
