Press Release from CLIFF Electronics, 2nd February 2016.


Cliff expands dual DC socket range to include surface mount version and introduces locking DC sockets.


Cliffs Dual DC and Locking DC Sockets

CLIFF Electronics’ much acclaimed dual gauge DC socket is now available in a surface mount version to facilitate efficient SMD PCB assembly of OEM products. The new version is available both taped and loose. It complements the original discrete PCB mounting and solder tag versions.


Accommodating both 2.1 mm and 2.5 mm industry standard plugs in a single socket, Cliff’s unique, dual DC socket offers a greater choice of power supplies for OEM and after-market supply. This simplifies design, purchasing and logistics, as OEMs need only fit one standard socket to meet the needs of their global markets.


Cliff’s dual DC sockets are already being designed into equipment where flexibility of available power supplies is advantageous. Markets where this flexibility has been welcomed include educational, medical, instrumentation, communications, audio-broadcast, audio-visual (AV) and industrial applications. Cliff dual DC sockets are widely designed-in, to reduce the need to supply different power supplies depending on geographical preferences; for example delivery to the USA or Europe.


All versions of Cliff’s dual DC socket are rated for 12V DC at 5A and fitted with switched contacts. The unique centre center pin also ensures a superior mechanical and electrical contact compared to conventional solid pins.


Other standard features include a body material made from PBT for superior temperature characteristics, tin-plated, copper-alloy contacts and RoHS compliance.


Cliff’s continuously expanding range of DC sockets also includes a range of latching DC plugs and sockets designed for applications requiring secure power provision where it is critical that power is not interrupted by accidental disconnection. Cliff’s PCB mounted, locking, DC sockets and plugs are secured by a simple push and turn locking mechanism. They are available in 2.1 or 2.5 mm versions, rated 2A @ 16V DC. The sockets also accept non locking 2.1 and 2.5 mm plugs for maximum flexibility.


Typical applications for locking power connections include point of sale, medical, data, monitoring, emergency lighting, stage audio equipment and charging.


Plugs are available in three options:



Cliff PCB mountable sockets have an insulation resistance of 100MΩ minimum at 500 V DC, dielectric withstand voltage of 500 V AC for one minute and feature a normally closed contact operated by plug insertion.


John Hall, general manager of CLIFF Electronics, comments; “Our dual DC connectors were an immediate success and are now widely available from major global distributors. The new surface mount options makes this flexible connector available for OEMs using automated assembly. Our new lockable DC socket provides a secure power connection for critical systems and products susceptible to knocking or vibration including audio effects pedals.”.
