ERNI, a leading supplier of PCB connectors, announced today it is offering new M8 male and female connectors designed for automation technology. The first products will be 3- and 4-pin female connectors, and a 4-pin version of the male connector. These connectors can be used to build a flexible I/O-connection on the circuit board. By employing surface-mount technology (SMT) termination, ERNI is enabling customers for the first time to consistently miniaturize their field devices.

Standard Interconnect Geometry

The interconnect geometry complies with the IEC 61067-2-101 standard. When the connector is plugged in, its protection rating meets IP67 in accord with the IEC 61076-2-101 standard. The traditional range of applications includes connecting sensors and actuators in automation technology. Now, however, the space-saving M8 connectors are also being used for power-supply and bus connections where M12 connectors or others are too large. Unlike the M12 connectors, M8 connectors are coded only via the contact arrangement.

M8 Ruggedness

The M8 connector''s terminal connections have been made so robust that it is possible to feed in bulk material packaging using an appropriate vibration device. The connector has also been designed for tape-on-reel packaging. As a result, despite their relatively high installation height, it is possible to mount the male and female connectors automatically using today''s automatic placement machines and feeders.

Version and Installation-Height Choices

Because of ERNI''s modular design, connectors can be manufactured in different installation heights and versions. Customers may choose the most suitable termination technique (SMT, press-fit, or through-hole reflow). The black insulator is made of high-temperature-resistant plastic, and is suitable for soldering with all the usual SMT soldering procedures. The new M8 connectors are already designed for lead-free processing, which will be mandatory beginning in July 2006.

Pricing & Availability

The connectors are available immediately. Pricing for the female connector starts at $2.10.
