Harting 21033812421 M12 D-Coded Ethernet Connector

The HARTING 21 03 381 2421 is a M12 circular connector specifically engineered for fast Ethernet networks requiring power over Ethernet (PoE). Its D-coding ensures proper connection orientation, while the integrated transformer facilitates efficient signal transmission. Designed for front mounting, this connector provides a secure and reliable connection in industrial environments. It is RoHS compliant and offers a degree of protection (IP65/67) when mated, making it suitable for harsh conditions. The connector utilizes LCP for the insert and brass with gold plating for the contacts, ensuring durability and optimal signal integrity.
