Signálny kábel EFB Elektronik K2402SW.20, 20 m, RJ-10 konektor–konektor, čierny

EFB Elektronik K2402SW.20 is a 20 m signal cable with RJ-10 male-to-male connectors designed for low-voltage signal transmission and telephone or data applications that use RJ-10 connections. The cable offers extended reach between devices, a flexible black outer jacket for discrete installation, and a single-unit supply suitable for replacing or extending existing cabling where RJ-10 interfaces are used.

Advantages

The cable provides a long 20 metre reach that reduces the need for intermediate equipment. RJ-10 male-to-male connectors ensure compatibility with devices and telephone handsets that accept this connector type. The black jacket offers basic protection against mechanical wear and provides a low-visibility appearance for office or equipment-room installation. The single-piece supply simplifies planning and installation.

Suitable for

• Telephone handsets and devices with RJ-10 sockets
• Low-voltage signal connections and short-distance data links using RJ-10
• Replacing or extending existing RJ-10 cabling in office or residential setups

Key specifications

• Cable length: 20 m
• Connector type: RJ-10 male to RJ-10 male
• Conductor type: copper-based signal conductors (shielding and exact conductor count vary by manufacturing batch)
• Outer jacket colour: black
• Intended use: low-voltage signal and telephone/data applications

How to use

Identify compatible RJ-10 ports on the devices to be connected and insert each male connector firmly into the corresponding socket until it clicks or seats. Route the cable to avoid sharp bends and pinching; secure with cable ties or clips where necessary to prevent strain on the connectors. For installations in high-traffic areas, route the cable along skirting or use protective conduits to reduce wear. Before finalising installation, test the connection to confirm signal or audio transmission is functioning as expected.

Recommendations

Avoid exposing the cable to excessive tensile force, moisture, or high temperatures. Do not bend the cable sharply near the connectors; maintain gentle curves with a radius appropriate for the cable thickness. For permanent installations, verify connector fit and signal integrity after routing and consider a spare cable for quick replacement if required.
