Konektor za žice EFB Elektronik 37512.1-100

The EFB Elektronik 37512.1-100 is a transparent modular connector (RJ10, 4P4C) designed for use with flat U/UTP (UTP) cables. Supplied in packs of 100 pieces, the connector is intended for wiring telephone and low-speed data connections where an unshielded 4-conductor modular plug is required. The clear housing allows visual inspection of conductor placement to facilitate correct termination.

Advantages

Transparent housing for easy identification of conductor order and correct insertion. Compatible with standard flat telephone cables and suitable for common 4P4C applications. Supplied in a 100-piece pack to support multiple terminations and small production runs. Unshielded design keeps the connector simple and cost-effective for non-shielded installations.

Suitable for

• Telephone handsets and short in-home telephone extensions
• Low-speed data lines requiring 4P4C connections
• Repairing or assembling flat U/UTP (UTP) telephone cables

How to use

Prepare the flat cable by stripping the outer sheath to expose the four conductors and align them in the required color sequence. Insert the conductors fully into the connector so each wire seats under its contact. Use a compatible crimping tool designed for RJ10/RJ11/RJ12/RJ45 connectors (EFB Elektronik Art.-No. E-MUC410) to crimp the connector securely. For other compatible crimp tools, check manufacturer recommendations.

Recommendations

For consistent terminations, use the recommended crimping tool (Art.-No. E-MUC410). Avoid using these unshielded connectors in environments with high electromagnetic interference; choose shielded alternatives if required. Store connectors in a dry place to prevent contamination of contacts.
