binder is expanding its M5 range with field-wireable, shieldable male and female cable connectors. Users can cut their own cable to the required length and fit the connectors on site. With 360° shielding, IP67 protection and a lightweight design, the compact circular connectors are suited to tight spaces in end-of-arm tooling, grippers, sensor boxes and camera systems.
The development was driven by growing demand for compact circular connectors that customers can assemble themselves. During development, binder identified M5 as a suitable size. Once the design was shown to be feasible, the company added it to the standard M5 range.
Shielding and contacts in the smallest of spaces
A field-wireable M5 connector must be easy to assemble correctly on site. The shielding and contacts also had to fit within the outer diameter of an M8 connector. The resulting male connector is approximately 41 mm long and the female connector approximately 38 mm long. During assembly, the cable shield is placed around a shielding ring, the individual wires are soldered in place and the clamping screw is tightened by hand.
The compact format also called for precision in production. Tooling, contact bodies and contacts had to be precisely matched so the contacts could be fitted correctly during production and customers could assemble the connectors reliably on site.
“The field-wireable M5 connector gives our customers the flexibility they need on site,” says Guido Werner, product manager at binder. “They can pull the unassembled cable through tubes or openings in their application, cut it to the length actually required and then assemble the connector themselves. The effort was worth it. The product has turned out to be a real masterpiece.”
Werner continues: “binder is currently the only manufacturer offering an available, high-quality industrial solution for a field-wireable connector in this size. Like all our M5 connectors, it complies with the detail specification DIN EN 61076-2-105 and is intermateable with the entire M5 portfolio.”
From robotics to machine vision
The connectors are designed for special-purpose machine building, robotics, including cobots, test and measurement and machine vision. Typical applications range from grippers and end-of-arm tooling to production and packaging machinery, optical sensors, industrial quality assurance and 2D, 3D and AI camera systems.
The field-wireable connectors join binder’s straight and angled moulded cable connectors and panel connectors for front or rear mounting. The new male and female connectors are A-coded, come with three or four contacts and accept cable diameters from 2.5 to 4 mm. They are available now, with custom versions available on request.
