Quad Port RJ45 Jack with LED 8P8C Connector JS2241B1DPH1（Cross Amphenol RJSAE-J384-04 ）

Product Overview

The JS2241B1DPH1 is a vertical 2x2 c in 8P8C format without magnetics. Contacts are formed from 0.35 mm phosphor bronze with a 50u inch nickel underplate, gold plating on the contact area and a minimum of 100u inch tin on the solder tails. The 0.20 mm copper alloy shield is plated with nickel and grounds through the PCB for EMI control, the black PBT housing is rated UL94V-0, and each port carries a red and a green LED for link and activity indication. The jack operates from -40 to +85 Degree C and its cavity geometry conforms to FCC Part 68 Subpart F rules.

Product Specifications

Product Features

• Four Ports in a 2x2 Stack: The vertical quad layout provides four 8P8C interfaces within a 32.00 x 32.00 mm footprint, ideal for multi-line switches and recorders.
• Red and Green LEDs Per Port: Each of the four ports includes a red and a green LED wired on dedicated pins for link and activity indication without extra board components.
• Gold Plated Contact Area: Phosphor bronze contacts with nickel underplate and gold plating in the contact area keep connection quality stable over repeated mating cycles.
• Nickel Plated Shield: The 0.20 mm copper alloy shield is plated with nickel and grounds through PCB tabs to suppress EMI between densely packed ports.
• FCC Part 68 Cavity Geometry: The jack cavity conforms to FCC rules and regulations Part 68 Subpart F, and the recommended panel opening is 27.90 x 25.40 mm.

Packing Details

Each JS2241B1DPH1 is inspected, packed in anti-static bags and sealed in labeled inner boxes before shipment. Standard export cartons with internal cushioning protect the shield, LEDs and through-hole pins during transport. Bulk, tray or tube packing can be arranged to suit manual assembly or automatic insertion equipment. Contact our sales team for carton quantities, current lead times and customized labeling requirements.

• Industrial Gateways: Compact quad port RJ45 Connector block for control cabinets and gateways.
• Routers and Modems: Four line passive interface for customer premises equipment.
• Embedded Control Boards: Dense Ethernet port cluster for industrial controllers.

Frequently Asked Questions (FAQ)

Q: Does this quad port RJ45 jack include magnetics?

A: No. The JS2241B1DPH1 is a passive jack without a transformer, so it must be paired with external magnetics or a PHY that integrates them. Keeping the magnetics off the connector gives designers freedom to place the transformer for optimum layout across all four ports, and the grounded nickel plated shield still provides EMI control between the stacked ports.

Q: Which LEDs are built into this RJ45 jack and how are they wired?

A: Every port carries two LEDs: a red LED and a green LED. On the left ports the red LED is wired between pins L4 positive and L3 negative with the green LED on the adjacent pair, and on the right ports the red LED is wired between pins L2 positive and L1 negative with the green LED alongside. All LEDs are driven directly from the PHY link and activity outputs through series resistors, so no separate indicator parts are needed on the board.

Q: What plating is used on the contacts and solder tails?

A: The 0.35 mm phosphor bronze contacts carry a 50u inch nickel underplate over all areas, gold plating on the contact area and a minimum of 100u inch tin on the solder tails. This combination protects the mating surface, supports wave and hand soldering and keeps the contact interface stable over the -40 to +85 Degree C operating range.
