For demanding environments, Binder USA LP has introduced a new generation of molded M16 connectors, which it said are engineered to deliver reliability and performance even in the harshest conditions. The M16 circular connectors are designed for applications ranging from heavy-duty machinery like construction cranes and excavators to precision-driven laboratory equipment.

These connectors must meet diverse requirements, ensuring stable and reliable connections in extreme conditions, such as freezing temperatures and exposure to dirt and dust. To address these challenges, they must combine high electrical performance with durability and resilience, noted Camarillo, Calif.-based binder.

binder redesigns connectors to be modular

binder said it has completely redesigned its latest generation of molded M16 connectors. The previous version included many existing parts from field-wireable connectors, not all of which were ideal for the molded version, the company explained.

With an expanding portfolio and increasing demand, the company said it decided to fundamentally redesign the product to use a modular system, enabling many common parts between the unshielded and shielded variants.

“A key feature of the new connector design is the reduction in components,” said Sebastian Ader, product manager at binder. “Thanks to the modular system, we only need one additional part for the shielded and unshielded variants. This allows us to produce much more efficiently, offering cost advantages to customers without compromising on quality.”

Developing the new M16 connector was particularly challenging, said binder, because it had to comply with both the M16 standard (DIN EN 61076-2-106) and the stringent AISG standard (for the eight-pin shielded variant) in terms of IP68 sealing and compatibility between different manufacturers.

By optimizing the sealing system, the new M16 system resolves compatibility problems that have previously led to insufficient sealing, the company said. It added that the new generation of connectors is lead-free, meeting the EU RoHS2 Directive 2011/65/EU, including 2015/863/EU.

M16 suitable for industrial, field applications

When redesigning the M16 molded connectors, binder said it paid particular attention to applications in industrial machinery, camera systems, and pressure sensors. These areas require maximum electrical reliability, and therefore a robust connector system that functions under difficult operating conditions, it noted.

“Crane and excavator applications are a good example. Here, fixed-plug connections are required,” said Ader. “Particularly in critical moments, such as when lifting heavy loads, it is important that the connectors not only fit securely, but are also quick and easy to use.”

A triangular design is intended to make the new M16 connectors are easy to handle, even in sub-zero temperatures or when wearing gloves, for example.

“The new triangular design not only makes handling easier, but it also minimizes dirt-prone areas and undercuts, which enables use even in very harsh and demanding environments,” Ader said. “The new connectors can be reliably mated, unmated and locked at any time.’

The molded M16 connectors also meet requirements for shock resistance, vibration tolerance, and tightness, said binder. “In summary, the robust design ensures a reliable connection in extreme temperatures, dirt, and moisture, minimizes the risk of failure, and ensures the continuous operational readiness of the machines,” it asserted.

“With the molded M16 connector, we have succeeded in meeting market demands in terms of technical properties, handling, and price,” Ader said. “All this makes our solution a future-proof choice for demanding industrial applications.”
