TE Connectivity 521125-1

Product Overview

Positive Lock receptacles are designed for ease of assembly and secure retention to mating tabs. They feature a reduced insertion force and a locking dimple that engages with holes in the mating tabs. The integrated housing insulates the terminal and can serve as a removal tool by deflecting a built-in depressor. A distinct "snap" action indicates proper seating, facilitating assembly in hard-to-reach areas. This design enhances safety by preventing accidental disconnection and reducing the risk of exposed live parts or circuit disruption.

Key Features:

  • Reduced insertion force
  • Locks onto tabs containing holes
  • Housing insulates and serves as a removal tool
  • Audible "snap" confirms proper mating
  • Suitable for automatic or semi-automatic equipment
  • Single and multiple circuit housings available

Certifications:

  • Recognized under the Component Program of Underwriters Laboratories Inc., File Nos. E66717 and E28476
  • Certified by Canadian Standards Association File No. LR7189A
