Mencom manufactures an expansive portfolio of industrial circular connectors for the harshest environments

Posted on December 12th, 2018

circular connectors

A circular connector is a coupling device built with a circular interface and cylindrical contact housing which comes with a huge variety of materials, sizes, contact layouts & types, and coupling designs. These circular connectors are commonly utilized for data, signal and power connections in the automation, manufacturing, military, aerospace and transit industries thanks to their rugged mechanical performance and ease of connectivity. They are also very versatile & flexible because of a wide range of contacts, voltages, and currents that can be conveniently featured based on the requirements of the applications.

Mencom is the leading manufacturer of circular connectors and their rugged solutions are engineered for reliable performance under the most extreme use in harsh environments. Mencom offers a complete line of circular connectors, including but not limited to, M8, M12, 1/2”-20 and M23 threads and MINI-Change connectors (MIN) with 7/8″, 1”, 1 1/8” threads. For the higher voltage (600V) applications, Power Distribution PMIN series with 1” 3/8 thread is also available. According to their recent product announcement, the coupling nuts and housings of the cordsets for 1” and 1 1/8” threads have recently been redesigned to deliver the better connectivity and stability. In addition to the power and signal connectors, Mencom offers M12 and 7/8” threads circular connectors for the industrial Network solutions such as DeviceNet, Ethernet, Foundation Fieldbus, Profibus, and Profinet.

Due to the numerous advantages of the circular connectors, it comes as no surprise that the military has developed the MIL-Spec 5015 series to meet the most stringent requirements to endure the toughest environments. Although the MIL-Spec 5015 circular connectors were originally designed for aeronautical and tactical service applications, they are becoming more commonplace in industrial applications that need the ruggedness of the MIL-Spec design, but do not need the military specifications. In order to meet the strong demand from various industries, Mencom has designed and offers a MIL-Spec 5015 Equivalent connector series with size 10SL (0.625”-24NEF), 14S (0.875”-20UNEF), 16S (1”-20UNEF) and 18(1.125”-18UNEF).

Mencom circular connectors are UL listed and IP67 rated to provide the utmost protection and quality for harsh environments. Multiple pole configurations and cable jacket materials including PVC, PUR and TPR are available for over-molded connectors along with a full line of accessories such as field wireable plugs, T-connectors, closure caps and plugs to name a few. Mencom has the largest variety of mounting styles for the mating circular receptacles.  Also, all the circular connectors are customizable upon request with fast turnaround at affordable costs. The range of the customization is from small changes to custom terminations and assemblies. Rugged armor options for extreme manufacturing environments are available for 7/8”, M12 and M8 circular connectors.

Mencom Introduced Industrial Protocol Gateways for Legacy Systems Integration

Posted on October 25th, 2018

Protocol Gateway
Not long time ago, serial-based communication was the standard in the networking industry. Hence, serial or CAN-based equipment, machinery, robots and PLCs that were manufactured more than a decade ago still can be found nowadays in many industrial sectors. In the Industry 4.0 era, technologies are rapidly evolving and modern industries keep looking for the faster networking solutions to transfer and process a larger amount of data because the outdated equipment cannot simply manage it. Upgrading perfectly running networking system is, However, a painful process both financially and effort-wise. Furthermore, changing sensitive utility infrastructure is always risky. Readapting existing equipment into a new layout can be just too overwhelming.

Mencom Protocol Gateway series can provide an efficient and economical solution for the cumbersome network update by seamlessly integrating new protocols into the existing layout and connecting them to outdated protocols. The supported protocols are Modbus RTU, Modbus TCP, Profinet RT/IRT, DNP3.0 Ethernet, DNP3.0 Serial, IEC 60870-5-101, IEC 60870-5-103, IEC 60870-5-104, IEC 61850 devices, and PLCs. 80 different protocol combinations can be selected in the firmware and integrated with 10 different hardware platforms based on the network/application requirements, which gives hundreds of flexible options to choose for end-users.

The Protocol Gateway series is equipped with powerful hardware platforms and a reliable software to manage the translation from protocol to protocol. They are designed to withstand the harshest environments with temperatures ranging between -40°C and +85°C degrees with up to 95% humidity. They also have a very long reliability with MTBF exceeding 20 years and comply with industrial EMC requirements/IEC 61850 chapter 3. SFP, Ethernet, TB5 or DB9 serial connectors are available for the connector types. The Din-Rail and Rackmount is the standard, and the wall mount is optional for models with the Din-rail mount.

All products can be embedded with Security (VPN over IPSec or OpenVPN function) that protects sensitive data from unauthorized accesses. Through this device, remote or unmanned site monitoring can be set up in a heartbeat. In addition, they share the same configuration tool, which helps a migration easy from one platform to another. This user-friendly Java-based configuration tool also helps the system integrator to manage data point mapping, polling frequency and configuration upload in with a fast and cost-effective manner. The data flow is monitored through the embedded debugging tool and it makes sure the conversion is performed as the applications require.

ILME Has Expanded Toolless SQUICH Technology to include 3 and 4 Pole (Size 21.21) Inserts

Posted on September 26th, 2018

compact rectangular connectors

ILME “SQUICH” spring terminal rectangular connectors have provided easy quick-connect solutions for a variety of industrial machinery in rugged industrial environments. With the SQUICH (already open) spring insert technology, no tool is required to terminate rigid and or flexible cables (up to 2.5mm2) to the contacts in the connector. The SQUICH inserts are up to 50% faster to wire than the conventional screw terminal connectors.  These inserts provide a safe and reliable connection thanks to the robust design which will endure severe vibrations on harsh manufacturing floors. In addition, when used with the IP65 housings, they offer gastight connections that meet the needs found in hazardous and controlled production environments.

The CK series SQUICH connectors are wired on the rear top of the insert. This keeps the wires from being bent and eliminates the tedious disassembly process of the inserts from the enclosures when re-wiring is required. They will save end-users significant time on installation, reinstallation or alteration of the connectors.

A unique coding system is available to prevent incorrect coupling that may cause consequent damages and breakdown. These coding pins can be set with multiple unique configurations, so several enclosures can be mounted together without fear of mating the wrong hoods with the wrong bases. According to EN 61984, the 3 and 4 pole (size 21.21) SQUICH inserts are rated 10A, 400V. Since cables are wired from the rear top, the measuring points for multimeter probes are located next to the connections.
