4 Pin Modular Jack 4P4C RJ9 Socket Jack Female Connector, 1 Port, Unshielded, Through Hole, R/A, No LED
Introduction:
This is a single port 4 pin modular jack designed for stable right angle through hole mounting on networking circuit boards. It utilize a durable black PBT housing that maintains structural integrity across a temperature range of -40°C to +85°C. The 4P4C RJ9 interface features Phosphor Bronze contacts with premium Gold over Nickel plating to support a consistent 1.5A current rating. By using a right angle configuration, this unshielded component effectively saves vertical board space while providing a high insulation resistance of 1000 mohms. Technicians utilize this reliable modular interface for telephone handsets and telecommunication hardware requiring secure 4-wire connectivity.
