Belden E100A21000S1 Cat6a Din Rail Jack T568B

Product Description

The Belden E100A21000S1 is a Cat6a DIN rail-mount punch-down jack wired to the T568B standard. It provides a structured cabling termination point for high-speed network installations, supporting the 10 Gigabit Ethernet performance demands of Cat6a infrastructure. The jack mounts directly to a DIN rail inside a panel or enclosure, making it well suited for industrial, commercial, and data-center environments where space and organization inside control cabinets are priorities. Network technicians and low-voltage cabling contractors are the primary installers. The T568B wiring configuration aligns with the dominant standard used in North American commercial installations.

This jack is used in structured cabling systems that require a clean, panel-mounted RJ45 termination point. It fits DIN rail installations inside electrical enclosures, telecom rooms, and industrial control panels. Because it is a Cat6a-rated component, it supports full-bandwidth 10GBase-T applications at the channel lengths defined by TIA-568-C.2-1. It is sold individually and is appropriate for both new installations and retrofit projects where Cat6a performance is needed inside an existing DIN rail assembly.

Key Features

• Cat6a rated for 10 Gigabit Ethernet performance
• DIN rail mount form factor for panel and enclosure installations
• T568B wiring standard for compatibility with North American commercial cabling practice
• Punch-down termination style for reliable, tool-terminated connections
• Single-unit packaging suitable for individual port additions or modular panel builds

Compatibility

Designed as an OEM-style Cat6a component for DIN rail structured cabling assemblies requiring T568B-wired RJ45 jack terminations.

Installation Notes

Installation is typically performed by a licensed low-voltage cabling technician or network infrastructure contractor. De-energize any associated network or PoE switch ports before terminating conductors at the jack. Use a 110-style punch-down tool to seat conductors fully and trim excess wire cleanly. Follow TIA-568 and local low-voltage wiring codes for conductor pair routing and bend-radius requirements.
