Fibre optic connector system is now available with SMA receptacle

Now available in standard SMA diode housings, optoelectronics specialist, OMC, offers its Keyed SMA (KSMA) fibre optic system in all of its standard SMA diode housings. The connector and receptacle system can be used for optically demanding and long service life applications, says the company.

The KSMA connector and diode receptacle system for OMC’s fibre optic transmitters and receivers deliver the rotational consistency of a keyed connector with the security and reliability of the SMA connector. The rugged, all-metal design, ensures the connector system is robust and is suitable for applications, across many industry sectors, including industrial and consumer, transportation, medical, aerospace, petrochemical and power distribution.

The KSMA connector system has a mechanical keyway mechanism that eliminates any rotational variation when a cable is mated to the transmitter or receiver. It also features the same secure hexagonal lock-nut fixing found in OMC’s standard SMA connector. No rotational variation between matings is useful because if a cable is disconnected and reconnected, traditional non-keyed SMA devices can rotate through 360 degrees, possibly resulting in performance variations and limiting repeatability. The lock-nut ensures that the optical fibre is held firmly in place, unlike spring-loaded connectors which can allow the fibre to move and change the attenuation of the link if the cable is subjected to any tension.

OMC’s KSMA system is now available in their H1 bulkhead housing, H22 PCB mount SMA housing, H3 single hole rear fitting panel mount, H11 single hole front fitting panel mount as well as the new VSMA (Vertical SMA) and HDMSA (high density SMA) device receptacles.

OMC’s fibre optic systems are used in many other applications across multiple industry sectors, including braking systems on trains, military radar systems, engine monitoring systems, automotive crash testing, machine vision in robotics, data transmission in CNC machinery in industrial applications, petrol pump control systems and high-voltage systems.
