RJ45Connectors (8P8C Modular Jacks) · 9 models

An RJ45 connector (8P8C modular jack) is the board-side socket for Ethernet cables in industrial PCs, gateways, networking equipment and POS terminals. The KINGCONN RJ45 series has 9 models: 1000Base jacks with integrated transformer (Tab-down 1x1 and Tab-UP 2X1, with LED, some with PoE), a basic jack without magnetics, an SMT mid-mount type, an RJ45+USB 2.0 combo and an IP67 circular waterproof jack — each with a downloadable engineering drawing on its part page.

How do I request a drawing or samples for RJ45?
Email service@kingconn.com.tw with the part number. Clicking any part card on a product page also pre-fills the enquiry subject with that part number. Our sales team will reply with the drawing, samples and pricing.
Can RJ45 be customised?
Yes. The Taoyuan R&D team covers the full path from design and tooling to volume production, including medical-device ODM experience. Send us the application and the requirement, and sales and engineering will assess it together.
Should I choose an RJ45 connector with or without an integrated transformer?
If the board has no separate Ethernet isolation transformer, choose a 1000Base model With Transformer: the magnetics sit inside the jack, saving external parts and routing. If the board already has a transformer, use the basic jack without magnetics. The KINGCONN RJ45 series lists both; it is stated in the part description.
How do I choose LED and PoE options on an RJ45 jack?
Pick a with-LED model when the panel must show link and speed status; pick a model marked PoE when the device is powered over the Ethernet cable, such as IP cameras and wireless access points. Both are available with integrated transformer in the KINGCONN series and named in the part description.
Is there a drawing for each RJ45 connector?
Yes. Click any part card on this page to open the part page and download its engineering drawing (PDF); the dimensions, materials and plating in our spec tables are transcribed from those drawings.
