Custom Connectivity Solutions

Posted on January 27th, 2015


In the industrial manufacturing Industry, connectivity failures can lead to costly downtime, temporary outage, and in the worst case scenario, cause a line down situation in the facility.

In most cases, the connectivity issues are caused by one of following conditions:

  • Small dusts or particles getting into threads and contacts between connectors
  • Liquids and chemicals causing corrosion of the connector
  • Damaged connectors and housings

If you are experiencing difficulties related to your connectivity, Mencom can provide you the solution to help you save money and time.

Industrial Ethernet and Network Connectivity Solutions

Posted on December 9th, 2014

Industrial network systems allow for real-time distributed control of many connection points from a single controller. These “network bus” systems reduce the total amount of cable required and can simplify the overall design. Mencom offers a broad range of industrial network connectivity products to streamline your installation.

 Industrial Ethernet

Industrial Ethernet Cordsets

Using Ethernet in industrial applications is becoming more prevalent. This has increased the need for Ethernet product that is built to handle harsh environments. Mencom has addressed this need with a series of rugged Ethernet products. Our E45V3 series connectors allow for an IP67 rating while using standard RJ45 connectors.

Mencom also offers M12 threaded over-molded cables, receptacles and field wireable plugs. We refer to this series with a MDE45 prefix. The MDE45 series utilizes M12 4 wire (D-Coded) connectors with 2 pair Cat 5e cables or M12 8 wire (A-Coded) connectors with 4 pair Cat 5e cable. The MDE45 is specifically used in Industrial Ethernet applications, and has teal cable using twisted pairs of wires inside. This connector has a unique keyway that is known as D-coded.

Ethernet Switches

Our Unmanaged Fast Ethernet Switches are designed to work in a variety of industrial environments.

These switches protect themselves from receiving too many broadcast packets. During normal use, broadcast packets will be forwarded to all ports except the source port. However, it will discard broadcast or multicast packets if the number of those packets exceeds a threshold in a preset period of time. When the preset period expires (about 800ms), it will then resume receiving broadcast or multicast packets until the threshold is reached again.

Each switch provides two redundant power inputs that can be connected simultaneously to a wide range of DC power sources. If one of the power inputs fails, the other live source acts as a backup to provide the power needs automatically.

Panel Mount Adapters

Mencom provides two new convenient ways to simplify your industrial Ethernet connection application.

Our pass-through single port M12 D-code is the ultimate in plug and play. The M12 connector on the outside of the panel available in male or female gender, will accept any D-code Industrial Ethernet M12 cables. The ‘Easy to Use Female RJ45 Jack’ on the inside of the panel accepts your standard RJ45 patch cord.

If your application calls for several Ethernet connections, our 4 port M12 panel is the answer. With 4 easy to access, custom labeled, M12 D-Code receptacles mounted to one plate, installation is quick and efficient. Each receptacle passes through the panel to a convenient female RJ45 jack on the inside. The plate comes with a gasket to ensure the environmental protection of your control cabinet.

UL Listing and CE

Mencom’s products have been certified for compliance with both Canadian and U.S. safety requirements by Underwriters Laboratories (UL), and the UL Listed mark now appears on most of our end products. UL is a non-profit organization that has developed more than 1,000 safety standards for 100 years and tested electrical devices for safety and functionality to the maximum. The UL Listing Mark means our products have met the highest industrial safety standard by UL and there were no modifications made from the original design for UL certifications testing.

Mencom’s products are also acknowledged by CE as being certified for compliance.  The CE marking is the manufacturer’s declaration that the product meets the requirements of the applicable EC (European Union) directives.

Are you looking for Fast & Reliable Sensor Connectors?

Posted on November 6th, 2014

Sensor cable Header

Mencom’s quick disconnect sensor connectors and cabling offers fast and reliable solutions for the connectivity between the sensors and the control panel. Our sensor cables are over-molded with a variety of outer jacket material with or without shielding to provide the next line of defense for harsh applications. Armored cables for enhanced protection are available in MDC, MAC and MEC series.

Sensor cables

Micro-DC Series (MDC): M12 Threads, A-coded

The MDC series has a single keyway which is known as A-coded. The M12 is a reference to the thread type used in the connection of this product. The euro color code (without a ground wire) and the single keyway (A-Coded) distinguishes the MDC from other connectors that are similar in size and function. The uses of these applications in industrial automation are limitless, but they are commonly used in factory automation for items such as sensors, actuators, motors, switches, safety light curtains and mats, and interlock switches to name a few.

Micro-AC Series (MAC): 1/2″-20 Threads, C-coded

 Although the MAC series is commonly used for AC or DC application and similar in size to the MDC series, it has some unique differences. The MAC series uses a ½-20 mating thread and has a first make last break extended ground pin. The use of a double keyway (C-Coded) prevents it from accidentally plugging into one of the other similarly sized connectors.

Euro-AC Series (MEC): M12 Threads, B-coded

The MEC series has a reversed single keyway which is known as B-coded.  This allows two unique M12 connectors to be mounted on the same panel without fear of incorrectly coupling connectors to equipment with varrying voltage and amperages.  As with the MDC and MAC series, the Euro-AC does not imply that they are only used in AC applications.

NAN Series (Pico): M8 Threads

The M8 (NAN-series) is often referred to as a “pico” or “nano” connector. The small size makes it the perfect choice when space is limited. The M8 is commonly used with many of the miniature proximity, hall-effect and photo-electric sensors. The NAN series is available in 2 different versions;  snap-on (available in 3, 4 and 6 pole) and thread-on (available in 3 and 4 pole). Male connectors in this series can be used to mate with both the snap-on and threaded females connectors.The male has threads and the small snap ring. Both snap-on and thread-on versions have the same water tight specifications (IP67) as well as the same voltage and amperage rating. It is simply customer preference as to which one suits their needs. Please note that there is no such part as a snap-on female receptacle.

10 Astonishing Facts About Arc Flash

Posted on October 8th, 2014

10 Amazinf facts about Arc Flash

Here at Mencom, we understand the dangers of arc flash and have developed a solution that helps prevent it.  Our Panel Interface Connectors (PICs) enable connectivity to components within a control panel without the need to open the cabinet.  Under OSHA, in hand with NFPA 70E standards, anyone opening a control cabinet is required to have training and wear protective gear.  This can make testing and maintaining equipment expensive.

The alternative, going without personal protection equipment or using a technician who is not certified, can be deadly.  As stated in the Control Design article, “…more than 2,000 workers were sent to burn centers this year from arc flash-related injuries.”
