Keystone module EFB Elektronik 37502.1 Flat Beige RJ-12

The EFB Elektronik 37502.1 Flat Beige RJ-12 keystone module is a slim, beige-coloured connector insert designed to provide a tidy RJ-12 connection point in keystone wall plates, patch panels and faceplates. Its flat housing reduces protrusion behind faceplates and helps maintain an unobtrusive profile for installations where space is limited. The module accepts a standard RJ-12 plug and is intended for voice and low-speed data telephone wiring where a compact keystone solution is required.

Advantages

The flat design minimises rear clearance and supports compact mounting in shallow boxes and slim faceplates. Beige colouring blends with many interior finishes and standard plate colours, supporting visually consistent installations. The keystone form factor ensures compatibility with a wide range of keystone wall plates and patch panels, allowing easy replacement or addition of RJ-12 outlets. Durable construction provides stable mechanical connection for repeated plug insertions.

Suitable for

• Telephone outlet installations in homes and offices
• Keystone wall plates and patch panel assemblies
• Space-constrained mounting boxes and shallow backboxes
• Service and maintenance panels requiring removable modules

Key specifications

• Connector type: RJ-12 (6P6C) compatible
• Form factor: Flat keystone module
• Colour: Beige
• Mounting: Standard keystone snap-in

How to use

Insert the module into a compatible keystone opening until it clicks into place, ensuring the front face sits flush with the wall plate or panel. Terminate the telephone leads to the RJ-12 plug or corresponding wiring harness as required by your installation practice, following standard wiring colour codes and ensuring secure connections. For removal, press the retaining clip and pull the module out gently to avoid damage to the surrounding plate.

Recommendations

Use the module with keystone-compatible plates and panels to ensure reliable fit. Avoid excessive bending of cables behind the module; maintain minimum bend radius recommended by cable manufacturer. For environments with high mechanical stress or exposure to moisture, consider using modules and plates rated for those conditions.
