Enhancing Efficiency and Reliability in Machine Building Industry through the Use of Connectwell’s Slim Relays
August 2023

The Machine Building Industry refers to the sector involved in the manufacturing and production of machinery and equipment. It encompasses various sub-sectors, including the production of industrial machinery, machine tools, agricultural machinery, construction equipment, mining machinery, and more.

Modern machines are getting increasingly more complex with the use of a higher number of control loops which can have a huge number of sensors and actuators. This calls for miniaturization of all components involved in the control system of the machine. Traditionally the relays used in the control systems for switching and isolation applications were quite large as they required switching larger currents at higher voltages. But with increase in complexity of the machines also the loads that need to be switched have become smaller while the number of loads to be switched have increased. The increase in the number of control loops also mandates that the components used in control circuits not only should be compact but also more reliable. 

Connectwell’s Slim Relays are the perfect solution for such applications as they are extremely compact yet highly reliable. In this blog post, we will explore the key features and benefits of Connectwell’s Slim Relays and how they contribute to the success of machine building applications.


Introduction to Connectwell Slim Relays

Slim relays are compact and highly efficient electromagnetic or static (also called electronic) switches that can be used for switching or isolation in any industrial application. Slim Relays are designed to be extremely compact (as low as 6 mm in pitch) so as to minimize their foot print in complex control panels. Yet their construction is such that they ensure that installation, wiring and maintenance are all easy. Slim Relays are also equipped with safety components that protect the electrical circuit and the relay itself.

Benefits of Slim Relays in Machine Building


Compact Relays = Compact Machines

Slim Relays enable to increase the wiring density of Control Cabinets and hence effectively shrink their size. This in turn allows us to build more compact machines with improved aesthetics and also reduce the cost of control cabinet fabrication and wiring.


Superior Aesthetics

Slim Relays have the same profile no matter what type of relay is utilized on them. So whether it is an electromechanical relay or a Solid State Relay or whether it is a 1CO or 2CO relay the profile of the SLim Relay remains exactly the same with only a change in the pitch. The multi level wiring that is made possible with the form factor of the slim relay also ensures more structured wiring which also adds to the aesthetics of the panel while simplifying complex wiring.


CE and UL Approved

Connectwell Slim Relays are CE and UL approved, which means that you can use them in any application without worrying about their suitability to a particular geography or industry. What’s more this gives you the confidence that these relays are designed with the correct standards and hence guarantee better performance.


Easier Installation, Maintenance and expansion

Connectwell Slim relays are designed to be truly modular in nature. From the fact that every individual relay is easy to replace without the need for replacing the entire module to the fact that each module is easy to stack next to each other and interconnect with the aid of external jumpers. Also these relays are provided with permanent laser etched markings and also easy to see markers which allow for easy visualization of wiring points and reduce wiring complexity. Lastly the LED indicator clearly helps identify if the specific relay is in operation.

Improved Control Cabinet Safety

Traditional relays often have exposed connection points which can be an electrical hazard during installation and maintenance. Connectwell Slim Relays have fully enclosed IP20 wiring points such that no electrical live point is exposed to human touch. Also the LED indication clearly indicates when a relay is in use and prevents any electrical accidents.





Superior Performance

Connectwell Slim Relays are designed and built for superior performance whether it is in terms of simplified wiring with a choice of screw clamp and spring clamp technology or with the aid of multi level connections to simplify complex electrical wiring. In addition to this teh relays themselves offer superior performance as they can be used continuously at their full rated current. The relays are also efficient in terms of the power consumption and operate at very high efficiency numbers.


Modern machines will keep increasing in complexity while posing demands for miniaturization. Components like Connectwell Slim Relay Modules are the building blocks that can be used to optimize the control cabinets for ensuring that these improving standards of design are met and the machines that are built are better and smarter.
