CONNECTOR SYSTEM WITH ALL STANDARD SMA DIODE HOUSE STYLES
OMC has announced that its Keyed SMA (KSMA) fibre optic system launched last October is now available in all of its standard SMA diode housings. The KSMA connector and diode receptacle system for OMC’s fibre optic transmitters and receivers deliver the rotational consistency of a keyed connector combined with the security and reliability of the SMA connector and is ideal for optically demanding and long service life applications. Thanks to the rugged, all-metal design, the connector system is robust and suits multiple applications, across many industry sectors, including industrial and consumer, transportation, medical, aerospace, petrochemical and power distribution. OMC’s KSMA connector system features a mechanical keyway
mechanism that eliminates any rotational variation when a cable is mated to the transmitter or receiver, while also featuring the same secure hexagonal lock-nut fixing found in OMC’s standard SMA connector. Ensuring there is no rotational variation between matings is useful because if a cable is disconnected and reconnected, traditional non-keyed SMA devices can rotate throughout a full 360 degrees, possibly resulting in performance variations and limiting repeatability, which can be problematic in optically-demanding applications. 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.

SPACE-SAVING CONNECTOR HOUSINGS
Thanks to angled geometry, the new screw-in variants of the Han 3 A connectors from HARTING are engineered to be space- saving and flat, for use on machines, control cabinets or terminal boxes. The external thread on the connector with lock nut supports quick and
uncomplicated assembly. The angled connector element can be swivelled in all directions and even be rotated through 360°. The new housing components are characterised by a slim external
geometry and optionally use a M20 or M25 thread for the connection. The housings are compatible with the existing Han 3 A series of inserts and meet the requirements of protection classes IP65 and IP67 by using an O- ring flat gasket, which is included in the delivery. In addition to the standard version in grey, other variants are available: an
EMV version and a Han M variant for increased corrosion requirements, among others. Only a circular cut is required for assembly. Installation effort has been reduced in comparison with the existing mounting variants of the Han 3 A with rectangular cut-out and at least two mounting holes. By affixing using the supplied lock nut, the mating direction can be adjusted and, if necessary, quickly changed again.

A GLOBAL CHARGING SOLUTION FOR EVSES AND EVS
New high-performance Excel Mate CC Connectors from Amphenol Industrial provide a global charging solution on both sides of the infrastructure and are now available at TTI. They are compliant
with IEC 62196-3, and also meet all
other necessary standards. These new EV and EVSE connectors from
Amphenol Industrial are robust, and can withstand more than 10,000 mating cycles unloaded. Insertion
resistance is greater than 100MΩ. Electrical specifications for the Excel Mate CC connectors include rated current of 63A maximum (AC), 200A maximum (DC), with rated voltage of 480V maximum AC and 1,000V/750V maximum DC. As an optional addition to the standard specification, the two DC+
and withdrawal force is less than 100N, while insulation
and DC- power contacts can be monitored by temperature-dependent resistor sensors. To cope with different environments around the globe, the Excel Mate CC connectors are IP44-rated in mated condition, and can withstand ambient temperatures of -30°C to +50°C.

PRE-ASSEMBLED FIBRE-OPTIC CONNECTOR RACK PANELS
Cliff Electronics manufactures a wide range of Feedthrough and conventional connectors mounted in the widely used, industry standard, 24mm-diameter XLR panel cut-out. Standardising on this commonly used format simplifies panel design and manufacture by having the same cut- out for every connector required. To further assist systems integrators by simplifying and speeding up
assembly time while reducing component count and cost Cliff are now providing 1U x 19” rack patch panels pre-assembled with commonly used fibre-optic connectors. Panels are available with an optional cable strain relief bracket. The four pre-loaded panels include one with the popular and widely
used ST MM (multi-mode) fibre-optic connector whose straight tip connectors utilise a bayonet-style coupling providing a simple twist-on and twist-off installation. The ST connector is one of the most popular connectors for multi-mode networks in buildings and campuses. The SC SIMPLEX rack panel meets the requirements of single mode
(SM) fibre-optic cables where each cable has one fibre and the small form factor LC DUPLEX connector is available as single and multi-mode (SM and MM) assembled panels used for duplex communication between devices where a separate transmit and receive signal are required.
