Product Description
Detailed Specifications & Features
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
