Product information

Description

DATACOM RJ45 to RJ12/RJ11 adapter — pack of 100 modular reduction inserts (MPN 4255). These white adapters allow insertion of an RJ12 (RJ11) plug into an RJ45 jack, providing a simple mechanical interface for telephone and low-speed data lines without changing the existing wiring. Pins 1 and 8 on the RJ45 connector remain protected from damage.

Advantages

The adapter set is supplied in a quantity of 100, is finished in white, and preserves unused RJ45 pins to prevent accidental contact or damage. It provides a quick, reversible way to accept RJ12/RJ11 plugs in standard RJ45 sockets and requires no rewiring or tools for basic insertion.

Suitable for

  • Connecting RJ12 or RJ11 telephone plugs to RJ45 wall jacks
  • Field testing and temporary conversions in installations
  • Installers, technicians, and small office network/telephone setups

Key specifications

  • Brand: DATACOM
  • Manufacturer part number (MPN): 4255
  • EAN: 8596250005565
  • Quantity: 100 pieces per pack
  • Color: white
  • Type: RJ45 (female) to RJ12/RJ11 (female) adapter / reduction insert
  • Purpose: mechanical converter for RJ12/RJ11 plugs into RJ45 ports; preserves RJ45 pins 1 and 8

How to use

Insert the adapter into the RJ45 jack until it seats firmly. Then insert the RJ12 or RJ11 plug into the adapter. The adapter provides a mechanical fit so that the plug engages the required central pins of the socket; no rewiring is necessary. To remove, withdraw the plug and then pull the adapter out of the RJ45 jack.

Usage recommendations

Intended for telephone and low-speed data connections; not designed for gigabit Ethernet. Use for temporary conversions, testing, or installations where only the central RJ12/RJ11 pins are required. Store in a dry environment and avoid excessive force when inserting or removing plugs to protect socket contacts.
