Conector de fibra óptica SC macho EFB Elektronik 53206.21 – conector SC simplex, beige/negro

EFB Elektronik 53206.21 is an SC simplex male fibre optic connector designed for multimode applications. The connector features a standard SC form factor in a beige housing with a black strain-relief boot, intended for terminating or adapting 2 mm multimode fibre cables where an SC male plug is required. It is suitable for simple patching and cable-assembly tasks that demand a compact, keyed SC interface and straightforward crimp-style installation.

Advantages

The SC male design provides a stable, keyed connection with low insertion effort and reliable mechanical alignment. The connector is supplied with a crimp-style termination that enables secure fixation of 2 mm buffered multimode cable, reducing the risk of fiber movement after installation. Its simplex configuration occupies minimal panel or patch field space, and the combination of beige housing with a black boot allows easy visual identification during installation and maintenance.

Suitable for

• Terminating 2 mm multimode fiber cables with an SC simplex male interface
• Patch cord assemblies and short multimode patching runs
• Field or workshop crimp-style installations where a simple SC plug is required
• Adaptation of cables to equipment with female SC ports

When it may not be suitable

This connector is intended for multimode 2 mm buffered cables and simplex terminations; it is not designed for multimode ribbon, tight-buffer less, or specialty fibers that require different ferrule types or polishing procedures. It is also not a duplex SC assembly, so applications requiring paired transmit/receive lines in a single housing will need a duplex solution.

Key specifications

• Connector type: SC simplex, male (plug)
• Fiber type: multimode
• Cable compatibility: 2 mm buffered multimode cable
• Termination method: crimp-style with strain-relief boot
• Housing color: beige with black boot

How to use

Prepare the 2 mm multimode fiber by stripping the outer jacket and buffer to the required length, clean the fiber end and cleave as specified for the chosen ferrule/polishing method. Insert the prepared fiber into the connector until it seats against the ferrule, then crimp the connector sleeve according to the manufacturer's crimp specification to secure the fiber. Fit the black strain-relief boot over the crimp area and verify physical contact and insertion before installing into equipment or patch panels.

What to consider before purchase

• Verify that your fiber cable is 2 mm buffered multimode and compatible with an SC simplex male plug
• Ensure you have the correct crimp tool and accessories for crimp-style termination
• Confirm that a simplex SC plug meets your channel routing and panel space requirements (not duplex)
• Check polishing/termination requirements and whether factory-terminated or field-terminated parts are preferred

Recommendations

Perform fiber cleaning and inspection before and after termination, use the recommended crimp die for 2 mm multimode cable, and verify optical continuity and return loss with appropriate test equipment. Store connectors in a dust-free environment when not in use to maintain performance.
