New M12-A connector combines power and signal contacts

26 January 2021

Binder announces the first models in a new range of over moulded M12 A-coded connectors. Its hybrid design means the single-cable solution contains both power and signal contacts.

The versatility and flexibility of the new hybrid connectors makes them ideal for applications in industrial indoor and outdoor areas where both power and signal transmission is needed in the smallest of spaces. In addition to sensors, actuators and camera systems, this also includes motors, drives and control systems.

Current and signal properties

The first available versions feature nine contacts – two gold-plated current contacts rated to 12A at 63 V and seven gold-plated signal contacts rated 0.5 A at 12.5 V.

The power conductors are inserted in a cable connector moulded with polyurethane (PUR) and feature a cross section of 0.75mm2 (AWG 18). The signal transmission conductors are 0.14mm2 (AWG 26).

As standard, the new connectors are supplied with 2m and 5m cables although custom cables lengths are also available from binder on request. For PCB applications, the connection to the printed circuit board is implemented using dip soldering technology (THR) for the power contacts and SMD technology for the signal contacts. The connectors can be processed in modern reflow processes.

Practical application and further development of the offer

The connector has been specifically designed for demanding outdoor applications. When mated, the connectors protect to IP67 and the operating temperature range is -25 to 85°C. The screw connection of the M12x1 standard thread is made of stainless steel although an optional plastic version is available.

binder is also announcing a connector variant with six contacts among the other models that will soon follow. This combines two current contacts – up to 16A – and four shielded signal contacts for data transmission. This enables future DC applications with power requirements of up to a maximum of 1kW and with simultaneous data connection up to 100Mbit/s.
