Optical Cable Corp. UMJA5E09 Cat5e Umj Keystone Jack Yellow

Product Description

The OPTICAL CABLE CORP. UMJA5E09 is a Cat5e UMJ (Universal Modular Jack) keystone-style jack supplied with a blank bezel in yellow. It is designed for structured cabling installations where low-voltage data outlets are terminated and dressed in a consistent, professional finish. The yellow color coding aids in quick port identification on patch panels, wall plates, and surface-mount enclosures. Network technicians and low-voltage installers use this jack to terminate horizontal Cat5e runs in commercial and residential data infrastructure.

This jack is suited for Cat5e structured cabling deployments in office, education, healthcare, and light industrial environments. The blank bezel configuration is appropriate where a clean faceplate appearance is required without printed port labeling. It fits into standard keystone-style wall plates and patch panel cutouts, making it a common choice for new construction rough-in work and retrofit outlet installations.

Key Features

• Cat5e rated for data network terminations up to 100 MHz
• UMJ keystone form factor fits standard wall plates and patch panels
• Yellow color coding for visual port and circuit identification
• Blank bezel included for a clean, unlabeled faceplate finish
• Sold individually for flexible quantity purchasing

Compatibility

Designed as an OEM-style replacement and new-installation component for Cat5e keystone jack positions in standard low-voltage wall plates, surface-mount boxes, and patch panel modules that accept UMJ keystone inserts.

Installation Notes

Installation is performed by licensed low-voltage technicians or electricians working under applicable structured cabling standards such as TIA-568. De-energize and disconnect all network equipment on the affected circuit before terminating the jack. Use a 110-style punch-down tool to seat conductors according to the wiring standard specified for the project (T568A or T568B). Avoid untwisting wire pairs more than 0.5 inches at the termination point to maintain Cat5e performance ratings.
