The 520250-2 is a PCB-mounted RJ14 modular jack connector designed for single port, 1 x 1 configuration with preloaded contacts. It features a side-entry (right-angle) mounting orientation with through-hole solder termination, supporting 6 positions with 4 contacts loaded. The connector utilizes gold-plated mating contacts (50 µm) over phosphor bronze base material, housed in PBT-GF material with UL 94V-0 flammability rating. With a height of 16.20 mm and PCB tail length of 3.80 mm, it is compatible with 1.57 mm recommended PCB thickness and operates to Category 3 performance standards. This connector is ideal for telecommunications, networking, and data communication applications requiring reliable modular jack connectivity with standard latch mechanisms and panel mount retention.
