## Summary description

The EFB Elektronik 37508.1V3 is a flat keystone module made of stainless steel featuring an RJ-45 connector. It is designed for reliable network connections and offers durability and a sleek appearance.

## Long description

The EFB Elektronik 37508.1V3 Flat Stainless steel RJ-45 keystone module is a compact, metal-bodied insert designed to provide a reliable RJ-45 network connection in compatible wall plates, patch panels and custom enclosures. Constructed from stainless steel with a flat profile, the module combines mechanical robustness with a discreet, low-profile appearance suitable for visible installations where a clean metal finish is required.
Advantages
This keystone module offers mechanical durability thanks to its stainless steel construction and a slim, flat design that reduces protrusion from mounting surfaces. The integrated RJ-45 connector supports standard patch-cord terminations and provides a consistent electrical contact for Cat5e-class network cabling. The metal housing aids in mechanical protection and contributes to a uniform visual appearance when installed alongside other metal fittings.
Suitable for
Installing RJ-45 Cat5e network connections in stainless steel or metal faceplates
Retrofit projects where a low-profile keystone insert is needed
Commercial or industrial premises requiring durable connector housings
Enclosures, patch panels and custom panels that accept standard keystone modules
When it may not be suitable
This module is intended for Cat5e-class RJ-45 terminations and physical installation in keystone-compatible cutouts; it may not be appropriate for environments demanding higher category performance such as Cat6 or Cat6a if higher data rates or reduced crosstalk are required. The stainless steel body provides mechanical protection but does not by itself guarantee full electromagnetic shielding unless the overall installation and mating connectors are designed for shielded connections.
Key specifications
Connector type: RJ-45 female keystone
Housing material: stainless steel
Form factor: flat / low-profile keystone module
Cable class supported: Cat5e
Mounting: standard keystone cutout compatible
How to use
Insert the keystone module into a compatible keystone slot in a faceplate, patch panel or custom panel until it snaps or locks into place. Terminate the network cable to the RJ-45 contact according to standard wiring schemes (e.g. T568A/T568B) using an appropriate tool and ensure secure mating with a patch cable. For shielded installations, verify that mating connectors and the faceplate provide the necessary continuity to the building ground if EMI protection is required.
What to consider before purchase
Confirm that your wall plate, patch panel or enclosure accepts standard keystone modules and has the correct cutout dimensions
Verify that Cat5e performance meets your network speed and noise-immunity requirements; choose higher-category modules if needed
Decide whether you need shielded end-to-end connectivity—metal housing alone may not provide complete shielding without compatible shielded connectors and grounding
Usage recommendations
Use this flat stainless steel keystone module where a durable, low-profile metal finish is preferred. Follow standard termination practices, check wiring continuity after installation, and ensure proper grounding for shielded networks to maintain signal integrity and safety.
