Harting 21033812803 M12 CAT5 Straight Connector

The HARTING 21 03 381 2803 M12 CAT5 Straight Connector is a high-performance connector designed for reliable data transmission in demanding industrial environments. It utilizes a robust M12 circular form factor with a straight PCB adapter design, making it suitable for front mounting applications. The connector features a screw locking mechanism and push-pull locking for secure connections, and is shielded to minimize interference. It supports Cat. 5 Class D up to 100 MHz, making it suitable for Ethernet and other high-speed data applications. Constructed with LCP for the insert, copper alloy for the contacts (gold plated), and zinc die-cast for the hood/housing, this connector offers excellent durability and performance. It is RoHS compliant with exemptions for copper alloy containing up to 4% lead by weight.
