Mencom Redesigned MIN Size III Cordsets to Improve Connectivity and Usability
Posted on August 6th, 2018
Mencom 1 1/8” MIN size III series circular connectors have been redesigned to deliver better connectivity and stability in harsh factory environments. Since MIN style connectors, sometimes referred to as Brad Mini-Change connectors, were introduced in 1968 as a way to quick-connect limit switches and pneumatic valves in the automotive industry, the Mini-Change connectors have been utilized in a wide range of industrial applications, including but not limited to, food & beverage, automated assembly,packaging and material handling equipment to name a few.
Although the original Mencom straight MIN size III cordsets satisfied the demanding requirements of the industrial control networks and applications, Mencom has continued to improve the quality and usability of these connectors. As a result, the original connector has been redesigned to better suit rugged environments. The coupling nut has been enlarged, which not only makes the installation process easier by giving a wider knurl area for better gripping, but also provides a more stable connection.
In addition, the coupling nut material has changed from anodized aluminum to nickel plated brass. The new brass coupling nuts are corrosion, salt and weld slag resistant, and are more durable to withstand harsh conditions than the old aluminum coupling nuts. Due to brass’s high melting point (1600F-1700F), the new coupling nut is more resistant to high temperatures, making them more resistant against warping and deforming and providing a longer lifespan. For extreme chemical conditions, stainless steel coupling nuts with the oversized design are also available.
Mencom MIN Size III connectors are UL listed and rated IP67, which is suitable for harsh environments. These connectors are available in multiple pole configurations including 9, 10, 12 and 19 pole. The cables are made with PVC, PVC TC-ER or rugged PUR jacket material with many standard shelf lengths. An optional male threaded coupling nut for the male cordset is also available.
Mencom Introduces Tight but Flexible Modular KADL Cable Entry System at IMTS 2018 – Booth # 134752 in IAMD USA – East Building, Level 3
The KADL Cable Entry System provides an easy to use, highly flexible, economical way to maintain enclosure integrity while still using pre-terminated cables and connectors. This KADL cable entry system allows for the insertion and sealing of pre-assembled cables with connectors into enclosures, machines and control cabinets. They can easily be expanded and adjusted, thanks to its unique modular design, providing high flexibility for various applications.
The modular structure allows a step-by-step, one click installation, and can accommodate from as little as 1 to as many as 25 cables into a housing wall. With only 18 grommets, a clamping range of 3mm to 32.5mm can be achieved. The grommets are ordered separately as accessories depending on various application requirements. No mounting screws are necessary when the thickness of the wall is between 1.5mm and 2.0mm. If the thickness is greater than 2mm the cable entry plate can be simply attached with screws.
The KADL frame is made of a robust Polyamide and provides IP65 rating when the installation is completed.
Below are some applications where KADL series can be utilized.
– Mechanical and plant engineering
– Measuring and control technology
– Drive engineering
– Mobile studio- and lighting technology
– Wind power and solar energy technology
– Electrical installation

Mencom Announces Easy, Flexible and Reliable Modbus Gateways for Seamless Conversions in Harsh Environments
Posted on May 23rd, 2018
Since its debut, Modbus has become one of the most popular protocols used worldwide. Modbus RTU (through serial connection) and Modbus TCP (through Ethernet networks) are often used in the crucial parts of industrial automation, substation automation, and building automation. Due to the slow migration of communication standard from serial-based (RS-232, RS-485, and RS-422) devices to Ethernet-based devices, however, a demand has been created for smart converters.
From simple to complex applications, Mencom offers a wide variety of Modbus series solutions. They are available from one to sixteen serial ports and feature several mounting options, such as DIN-rail, Field Mount, or Rack-Mount. The Entry-level products provide seamless conversion from Modbus RTU to Modbus TCP and they require almost no configuring. The wireless version also enables high-speed wireless communication for Modbus protocol. Mencom Modbus Series are enhanced with harsh environment operational capability, vibration resistance, power or serial port isolation for equipment and device protection, redundant power supplies, and many more special options. In addition to excellent reliability, enhanced responsiveness can be achieved through redundancy and concentrator function for the most critical applications.
A data concentrator function is a proprietary mechanism to enhance responsiveness on Mencom Advanced/Industrial Modbus Gateways. The Modbus Gateway has to wait for a master device’s request, then it has to convert and relay information to a field device. Once a response is returned from the field device, the response is then converted and relayed back to the master device. This process generally results in significant negative impacts on the responsiveness. Instead, Mencom Advanced Modbus Gateways with the data concentrator function automatically continue to poll IEDs at a specified interval and store the data in their internal memory waiting for master device’s requests. Once the request arrived, the return data will be retrieved from the internal memory of the Modbus Gateways. This tailored process provides several positive implications on the system performance: the master device may need just one connection and one query to get all data at once, the response time will be dramatically reduced, and many different data structures can be accessed on demand.
Mencom Advanced/Industrial Modbus Concentrators offer an additional redundancy feature that can be implemented via the proprietary communication protocol. For instance, a number of IEDs are connected in multiple chains through serial ports where the primary Modbus gateway and the secondary Modbus gateway are connected on each end of the chains, and Ethernet links with fiber or copper connections are installed between the primary gateway and the second gateway. Both primary and secondary gateways may be further connected to a master through different redundant rings.
The secondary gateway usually performs receiving and recording the data under normal circumstances. In the event of a network breakdown, however, one of the reachable gateways will take over the communication with the master, relay back the link to the master together and notify a link failure message. On the other hand, if there is a serial link failure, the secondary gateway will autonomously poll the missing data and update the primary gateway memory ensuring the data relayed to master is complete. This feature helps the network significantly reduce down-times and provides extra protection for the utility or the substation from accidental or intentional failure coming from the outside of the system.
