control panel assembly time PUSH-IN connection technology has demonstrated an assembly time saving of up to 55 per cent while providing a high conductor retention force and handling multiple conductor types

oremost Electronics, the engineering-led Essex based importer and specialist distributor of electromechanical components now offers a range of 22mm control panel switches from IDEC with secure screw-less push-in terminations which greatly reduce assembly time. Commonly used in control panel and machine building applications the Push-In termination technology option is available on the industry standard YW and HW series and the CW series (flush mounting) switches. Each of these three series of switches are for 22mm mounting and available as a push button (with and without illumination), selector switch, key selector switch and pilot light/indicators.
In recent years wire termination technology has slowly migrated away from the traditional screw connector and moved towards “screw-less” terminations. This was first seen on the simple DIN rail terminal and then on to other hardware such as PLCs, relay sockets and more. Initially this change to screw-less was done with a “spring clamp”, however this still required a screwdriver to open the spring to allow the cable to be inserted. More recently, the spring clamp has taken a step sideways and the “push-in termination” has taken the lead. This simple, safe and smart connectivity is now referred to by IDEC as the S3 termination. With the PUSH-IN connection technology, the force on the conductor is generated by a pressure spring made of high-quality stainless steel. The spring sits in a cage and is automatically opened upon connection and only released when a release tool is used. Alan Vincent, sales director of Foremost, comments, “It’s often said that time is money. The IDEC S3 push-in principle now greatly reduces the amount of time required to wire a control panel. A recent study demonstrated a time saving of up to 55% when compared to more traditional methods, while still providing a high conductor retention
force and a complete way of handling multiple conductor types.”
The three IDEC switch series with push-in connectivity are: The cost-effective YW series (22 mm industrial switch family) which delivers all the key features required by the industrial automation market including push button, illuminated push button, key and selector switch.
Where the style of a product is important and must be matched by high performance the CW series (22 mm flush design industrial switch) is a popular solution. This product range commonly is
used in medical appliances, consumer applications and the food industry, where aesthetics and reliability are the key to success.
The HW series (22mm industrial switch) is IDEC’s largest portfolio of switches and actuators for the industrial automation market and includes rotary switches, selector switches, combined rotary and push-button, 4 or 5 position selectors and many more options.

Feed-through connectors in pre-assembled rack panel
Cliff’s FeedThrough connector range allows designers to integrate audio, video, digital, optical, networking and data feeds into professional equipment for broadcast (studio and mobile), lighting, audio, industrial applications, instrumentation and control connectivity. To further aid product designers and systems integrators Cliff can now supply 1U x 19” rack panels preassembled with up to 16 connectors to meet the end system’s requirements. Specifying preassembled connector panels assists systems integrators by simplifying and speeding up assembly time while reducing component count and cost. Cliff’s rack panels feature a connector labelling strip located on the front and a cable strain-relief bar is fitted at the rear to secure internal wiring against strain and vibration. The most popular connectors in Cliff’s FeedThrough range are CAT 5e RJ45, CAT 5e Shielded RJ45, CAT 6 RJ45, CAT 6 Shielded RJ45, HDMI Female – Female, USB 3.0 A-A, USB 2.0 B-A and USB 2.0 A-A. All widely used in data and audio-visual applications. CLIFF ELECTRONICS |

liff Electronics have developed a very wide range of FeedThrough (FT) and conventional connectors designed to be mounted in the industry standard 24mm-diameter XLR panel cut-out. With over 20 different connector types now available in this standard format, panel design and manufacture is greatly simplified. Cliff’s FeedThrough connector design allows standard, off the shelf, cables to be used for internal connectivity further simplifying assembly.
