RJ45 Male to 8-Pin Screw Terminal Adapter Manufacturer

RJ45 Male to 8-Pin Screw Terminal Adapter for Solderless Signal Breakout

The PROUNTA RJ45 male to 8-pin screw terminal adapter provides reusable access to all eight contacts of an 8P8C plug. Each pin routes to a separate position on the removable green block, allowing low-voltage wires to be connected without soldering or crimping. A small slotted screwdriver is included.

This passive breakout is not a BNC connector, video balun, media converter, surge protector or active extender. It contains no transformer or signal processing. Users must define pinout, signal, voltage and current for their equipment. See Wikipedia’s modular connector overview.

Direct RJ45 8P8C Male-to-Terminal Access

The transparent male plug inserts into a compatible RJ45-style port. Its eight contacts route through the black housing to eight screw positions. The one-to-one breakout supports inspection, adaptation or reassignment when equipment uses RJ45 for serial communication, sensors, alarms, relays or proprietary control.

Remove the terminal block before wiring and reinsert it after conductors are secured. Verify every position with a continuity tester because equipment vendors may use custom pinouts.

Solderless and Reusable Field Wiring

Prepare each wire, insert it fully and tighten the screw with a flat-head driver. The clamp supports future rewiring without replacing the RJ45 plug, useful for prototypes, test benches and control-panel maintenance.

Insufficient torque can cause intermittent contact; excessive torque can damage fine conductors or the block. Use ferrules when required. Learn more in Wikipedia’s screw terminal article.

Technical Specifications

Confirm dimensions, wire range, terminal torque, voltage/current rating, pin continuity map, materials and compliance documents for the selected production model before publication or ordering.

Applications and Electrical Limitations

Applications include CCTV control lines, DVR accessories, RS-232/RS-485, data acquisition, relays, sensors, alarms, industrial panels and test fixtures. It is useful when equipment uses an RJ45 socket as a multi-pin interface but field cable terminates as individual wires.

The adapter should be treated as eight individual conductors, not as four automatically managed Ethernet pairs. If a CCTV controller, serial device or sensor assigns a signal to a specific RJ45 contact, connect the matching screw position exactly as documented. Reversing polarity or joining grounds incorrectly can damage connected equipment. For repeat production, create a pin-assignment drawing, mark both ends, perform 100 percent continuity testing and lock the approved wiring into the work instruction.

Screw terminals can disturb controlled impedance and pair geometry. Do not promise 10/100/1000BASE-T unless the exact assembly is validated. Do not apply PoE or power without confirming pinout, polarity, conductor size and current rating. For network plugs, browse PROUNTA’s RJ45 connector catalog.

How to Wire the RJ45 Screw Terminal Adapter

1. Obtain the connected equipment’s RJ45 pinout; do not assume a universal Ethernet assignment.
2. Use a continuity tester to confirm which screw position corresponds to each plug contact.
3. Unplug the green terminal block from the black adapter housing.
4. Strip each wire to the terminal manufacturer’s recommended length.
5. Insert conductors fully, keeping stray strands outside adjacent terminals.
6. Tighten each screw with the supplied flat-head screwdriver using appropriate torque.
7. Perform a pull check, inspect polarity and verify continuity and absence of shorts.
8. Reinsert the terminal block and connect the RJ45 male plug only after power is removed.

OEM Manufacturing and B2B Supply

PROUNTA supplies specialty adapters to distributors, security brands, integrators, panel builders and test-equipment manufacturers. OEM/ODM options include terminal colors, pin markings, instructions, blister packs, barcodes, tools and cartons. Proprietary pin maps or harness versions can be reviewed.

Before production, provide the mating device, pinout, wire range, electrical limits, environment, packaging and volume. Samples should verify fit, retention, continuity and intended function.

Frequently Asked Questions

Is this product a CCTV video balun?

No. It is a passive pin-breakout adapter and contains no impedance-matching transformer. It may connect low-voltage CCTV-related wiring, but it does not convert video by itself.

Does it convert RJ45 to BNC?

No. There is no BNC interface. The output is an eight-position screw terminal block for individual wires.

Can it carry Ethernet data?

It provides electrical continuity, but the terminal geometry may not preserve high-speed Ethernet performance. Use it for validated applications only and do not promise a data rate without testing.

Is the adapter wired to T568A or T568B?

The standard product is a direct pin breakout rather than a cable wiring scheme. Confirm each pin-to-terminal position with the drawing or continuity tester.

What wire sizes fit the terminal block?

Typical versions accept approximately 16–28 AWG, but conductor type and ferrules affect fit. Confirm the exact terminal datasheet before ordering.

Can the terminal block be reused?

Yes. The pluggable block and screw clamps support rewiring when undamaged. Inspect threads and clamps before reuse.

Is the screwdriver included?

The illustrated retail kit includes a small slotted screwdriver. Confirm tool inclusion and packaging quantity for bulk OEM orders.

Can PROUNTA customize the pinout or packaging?

Yes. Pin mapping, labels, terminal colors, instructions and packaging can be evaluated for qualified volumes. Contact PROUNTA with drawings and requirements.
