Industrial power connector types
Each industrial power connector type needs its own line on the request. A shared headline price across types usually means a field was skipped.
- Rectangular heavy-duty housing
- Threaded metal circular shell
- Wire-to-board header
- Stud, lug or barrier terminal
- Magnetic breakaway shell
LinkScope Sourcing 42 asks plants to quote industrial power connector types on one matrix. Rectangular housings often use removable crimp contacts and a lever hood. Circular shells add a coupling thread and a keyway. Headers fix the pitch and the tail length. Studs and barrier strips care about screw torque and lug width. Magnetic shells add retention force and polarity. None of those sentences says the desk holds stock.
Costs that must sit outside the unit price include tooling for a custom contact, plating upcharge, packaging, freight, duties, spare contacts and any hipot fixture. If a license or a coding dongle appears on a quote, treat it as a host-equipment line, not as part of the shell.
Ledger each supplier must fill
Use the same columns for every reply. Leave a cell blank when the plant has not answered. Do not copy a family datasheet into a blank cell.
| Column | What a complete cell contains | Buyer check |
|---|---|---|
| Exact model | Manufacturer name plus the configuration code | Reject an answer that stops at the family name |
| Current basis | Amperes, ambient, conductor, such as 30 A at 40 °C on 10 AWG | Reject a bare ampere number |
| Voltage and hipot | Working voltage and any dielectric test, such as 1500 VAC for 60 seconds | Ask whether production pieces see that test |
| Plating | Finish and thickness, such as 0.76 µm gold over nickel | Ask for the thickness method |
| Ingress protection | Code, standard and mated or unmated state | IP67 mated is not a hose test on an open face |
| Connector mating cycle | Count and the load during the test, such as 500 cycles unpowered | Powered cycling is a different claim |
| Commercial basis | Quantity, currency, per piece or whole order, Incoterm, lead time | Normalize freight before reading price |
| Exclusions | Contacts, hoods, gaskets, tools, drawings, inspection | List them before comparison |
Impedance of the mated power path, when the buyer cares, should be a milliohm limit with the measurement accuracy of the meter named. Calibration traceability of that meter is requested from the plant. It is not issued by this desk. A 5 mΩ contact and a 15 mΩ contact can both be labeled power contacts.
Worked buyer situation. Background: three plants answered a 200-piece circular shell order for a US warehouse. Process: the ledger showed one price excluded the socket contacts and quoted 25 A without an ambient, while another included contacts and stated 25 A at 20 °C. Result: the buyer held the comparison until both replies used 25 A at 55 °C with contacts included. No savings percentage was calculated.
Compatibility questions on a type change
When is a rectangular housing not a stand-in for a circular shell?
Panel cutout, keying, wire dress and the hood latch differ. A contact that is rated 16 A in a rectangular module can have another current in a circular insert because the thermal mass changed. Ask for the insert arrangement drawing, not a marketing photo.
What does an equivalent plating statement need?
Nickel underplate thickness, gold or tin thickness, and whether the figure is a minimum. Tin on a power contact and gold on a signal contact inside one housing should be two lines. A salt-spray hour count without the specification number is incomplete.
How should Power over Ethernet stay out of this matrix?
If the cabinet also has a powered-device port, put the Power over Ethernet class on the switch line. The shell current is still the contact current. Mixing a 90 W port budget into a 10 A contact cell makes the quotes impossible to normalize.
Which documents are in scope and which are exclusions?
Ask whether the price includes the current drawing, a contact map, a pull-test note such as 50 N on the crimp, packing for export, and incoming-inspection support. Tooling that is charged once should be a separate amount with a currency.
New lot or surplus contacts?
A date-coded production lot makes the plating age easier to read. A surplus lot can be the practical route for a discontinued insert, provided the seller states condition, storage history and how many connector mating cycles remain, for example 200 of a 500-cycle rating. Price those lots apart. A chassis-style refurbished label does not describe a loose contact bag.
