ERNI expands M12 line of connectors

ERNI expanded its range of M12 automation connectors to include a 4-pin version with D-coding. These connectors can be used to implement a flexible input-output (I/O) or field-bus connection on the circuit board, explained the company.

Traditionally used to connect sensors and actuators in automation systems, the M12 connectors are now recommended for nearly all field-bus specifications and meet the IP67 protection standards rating (IEC 61076-2-101). An expansion (Amendment 1) of the IEC 61076-2-101 standard describes a 4-pole, D-coded variant specified for a higher protective class of Industrial Ethernet applications, ERNI said. From the perspective of transmission technology, these requirements correspond to those of a Category-5 modular jack (RJ45) connector, according to the EIA/TIA standard. The D-coding prevents the connector from being confused with the A-coding used for sensor-actuator wiring, or the B-coding used with some field buses, the press release further explained.

The company added that the connectors' modular design concept makes it possible to produce connectors in different sizes and versions. Customers may choose the desired connection techniquesurface mount, 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 surface mount procedures. The M12 connector's contacts are so robust that a vibration device can be used to feed them in bulk-material packaging. Tape-on-reel packaging is also available.

The M12 connectors are priced at $1.50 each in volume orders.
