M12 connectors as SMT variants for efficient automated processes

10-04-2024 | Binder | Industrial

binder offers products from several M12 series as SMDs. They are appropriate for further processing in fully automated processes, such as for the particularly dense, double-sided assembly of PCBs. These are utilised in automation technology devices, sensors and actuators and in robotics.

In the course of miniaturising electronic assemblies, surface mounting has proven itself in component assembly with high component density. In contrast to the classic THT or THR process, the SMD contact pins are placed directly on the surface in the SMT process and connected using solder paste instead of being inserted through the PCB and then soldered. This allows notable space savings: for example, many connectors can be mounted with very small distances in one plane, as is required for passive/active sensor distributors in automation technology.

SMDs are usually supplied on so-called blister tapes (tape and reel) - a type of packaging that is suitable for automated further processing by the customer. In addition to space-saving PCB assembly, this ability to automate production is a significant advantage of surface mounting. It is characterised by its cost-effectiveness, especially for large quantities or when several connectors are to be processed on one PCB. Furthermore, advantages can be attained in terms of heat dissipation and signal integrity, as well as a reduced susceptibility to errors during assembly.

The company's SMT products are offered in versions with 4, 6 and 8 contacts and with different codings. They are provided in shielded and unshielded versions. The M12 connectors are also available in different versions – for example, as a set with different flange housings, as a built-in part in blister packaging, or as tape and reel packaging for automated processing.

In detail, these are A-coded M12 connectors from the 713/763 series, B-coded components from the 715/766 series and connectors from the 825/876 series with D-coding and the 876 series with X-coding.

Depending on the coding, the M12-SMT variants are suitable for different applications: A-coded for sensors and DC power, B-coded for Profibus and D- and X-coded for 100Mbit and 10Gbit Ethernet, respectively.

All M12 products from the binder provide industry-relevant protection, as compared to IP67, against the ingress of dust and water. The company variants are based on the current market standards with regard to the PCB drilling pattern, which means that switching to binder products requires little effort.

Areas of application include factory and process automation, instrumentation, robotics, and sensors and actuators.
