5.0mm and 5.08mm Pluggable Terminal Blocks
5.0mm and 5.08mm Pluggable Terminal Blocks
This collection contains 21 product listings for detachable terminal-block connections centered on 5.0mm and 5.08mm pitch systems. Available formats include PCB plug-and-header sets, separate plugs and headers, inline male/female docking pairs, locking cable connectors, through-wall panel connectors and a rail-mounted docking product.
What These Connectors Do
A pluggable terminal block separates the wire-termination component from its mating interface. Depending on the selected product, the plug mates with a straight or right-angle PCB header, two wire-side halves create an inline connection, or a matched pair passes through a panel. This supports modular assembly and service disconnection without releasing every conductor.

5.0mm vs. 5.08mm Pitch
5.0mm and 5.08mm are not the same pitch. 5.08mm equals 0.2 inch; 5.0mm does not. The 0.08mm difference per contact accumulates across longer connectors, so the two pitches must not be treated as footprint-compatible or mechanically interchangeable.
5.08mm also does not “align with a 0.1-inch grid” in a way that guarantees compatibility. A 5.08mm contact interval spans two 2.54mm grid spaces, but the full footprint still depends on pin dimensions, row position, housing geometry and mounting features.
How to Select the Correct Variant
- Confirm whether the required pitch is exactly 5.0mm or 5.08mm.
- Choose PCB-to-wire, inline cable-to-cable, panel feed-through or rail-mounted construction.
- Select plug only, header only, one mating half or a complete pair.
- For PCB products, choose straight, right-angle, vertical or side-exit geometry as listed.
- Select the exact position count. Some families reach 24P, while others stop at 8P, 10P or 12P.
- Check whether a latch, PCB lock, fixing screw, flange or guide-rail feature is required.
- Verify screw-clamp or screw-free termination and the conductor range for that exact listing.
- Confirm package quantity, which varies between individual sets and 2-, 5-, 10-, 20-, 50- or 100-piece packages.
- Compare mechanical drawings for footprint, pin size, mating depth, keying and enclosure clearance.
PCB, Inline and Panel Formats Are Different
PCB sets use a soldered male header and a removable wire plug. Inline docking products terminate wires on both mating halves and do not require a PCB. Through-wall connectors use panel hardware to carry the connection through an enclosure. The rail-mounted listing introduces another mounting format. These products should not be substituted based on pitch alone.
Mixed-Pitch Listings
Several products combine 2.54mm, 3.5mm, 3.81mm, 3.96mm and 5.08mm variants. One listing is primarily labeled 3.81mm but appears in this collection through mixed options. Only variants explicitly marked 5.0mm or 5.08mm fall within this page’s pitch scope. Review every option before ordering.
Ratings Are Product-Specific
The collection does not share one verified 300V/15A or 22–12AWG specification. Product construction, conductor termination and published values vary, and some listings do not provide complete traceable ratings. Use the data for the exact selected male/female combination rather than transferring values between families.
Final suitability depends on conductor size, number of loaded poles, ambient temperature, contact temperature rise, PCB copper, creepage, clearance, enclosure design and applicable equipment standards. Do not infer mains, motor-drive, solar, energy-storage or other high-energy suitability from pitch or marketplace wording alone.
Compatibility and Naming Boundaries
2EDG, 15EDG, KF2EDG, 2EDGRK, 2EDGWB and similar codes are family references or search identifiers, not proof of cross-manufacturer interchangeability. “Phoenix,” MSTBV or related terms in a listing do not establish original manufacture or guaranteed mating compatibility. Match pitch, contact geometry, polarization, latch style, mating depth and footprint.
A pluggable connector is not automatically rated for live mating. Disconnect power before insertion or removal unless the exact connector and complete system carry an explicit live-disconnection rating.
Typical Uses
When correctly engineered, these connectors can support removable control wiring, power and signal distribution, relay boards, test equipment, modular controllers and enclosure feed-through connections. Application examples are not universal electrical ratings.
Frequently Asked Questions
Are 5.0mm and 5.08mm interchangeable?
No. Their center spacing differs and the error increases with every position.
Does every product include a plug and header?
No. Some variants are plug only, header only, male only or female only. Select a pair or set when both halves are needed.
Are all headers PCB mounted?
Most straight and right-angle headers are PCB components, but this collection also contains inline, through-wall and rail-mounted formats.
Is every product rated 300V/15A?
No. Ratings and conductor ranges are listing-specific and are incomplete for some products.
Can a 5.08mm plug from one family mate with any 5.08mm header?
No. Equal pitch does not define contact shape, keying, housing width, latch design or mating depth.
Can these connectors be unplugged while energized?
Do not assume hot-plug capability. De-energize the circuit unless the exact system is expressly rated for live mating.
Ordering Checklist
Verify exact pitch, positions, connection format, termination method, included halves, header orientation, locks or flanges, mounting method, footprint, conductor range, package quantity, electrical ratings and supporting compliance documents.
