LinkScope Sourcing 42 prepares a written brief so plants can quote the same rugged industrial power connector requirement. The desk is not a connector plant, does not publish stock, and does not treat a family name as proof that two shells interchange.
Bring the connector family, contact count, pitch, current and voltage rating, termination method, keying, plating, ingress protection code, wire or PCB interface, quantity, US destination and requested timing. A TIA-568 cabling overview can suggest questions about the cable plant. It does not certify the proposed shell.
A 20 A nameplate at 25 °C is not the same offer as 20 A at 70 °C. Ask each plant to state the ambient, the conductor size and whether the figure is continuous current.
Record 48 VDC, 250 VAC or 600 V as the circuit requires, plus the current the contact must carry after derating. Separate this line from the host Power over Ethernet budget. A 30 W or 90 W powered-device load does not set the shell rating.
State crimp, screw, solder or PCB tail, the pitch such as 5.08 mm, and the wire range, for example 14 AWG through 10 AWG. A drawing callout of contact size belongs in the same sentence as the termination.
Name the ingress protection code you need, such as IP65, IP67 or IP69K, and the connector mating cycle count the plant will stand behind, such as 100, 500 or 2000 cycles. Ask which standard and which mated or unmated condition the code uses.
Request a current datasheet, contact map, plating thickness such as 0.76 µm gold over 1.27 µm nickel, and the hipot or pull-test basis. Calibration traceability of the meter is a document question, not a credential of this desk.
The same family name can hide a different environment. Write the route before you compare factory quotations on total procurement scope: configuration, quantity, currency, destination, freight and exclusions.
A 2 rack unit rectifier shelf may feed 48 VDC at 40 A. Ask whether the shell is on the busbar, the battery string or a branch breaker, and what impedance in milliohms the contact path is allowed to add. Switching capacity of the rectifier stays on the power-plant line.
Temperature from -40 °C to 70 °C, vibration and a gasketed door change the sealing question. State whether the connector is mated during wash-down. Runtime of the DC plant is a battery question and should not be copied onto the shell datasheet.
Confirm conductor gauge, strain relief and the panel cutout. A 19-inch rack position does not describe the contact. If the whip also carries a sense pair, mark that pair separately from the power contacts.
Background: a US integrator needed 120 mated pairs for outdoor cabinets and had two shell drawings with different keying. Process: the brief forced both plants to answer 20 A at 55 °C, IP67 mated, crimp for 12 AWG and a 500-cycle claim with the test method named. Result: one offer dropped the temperature, so the unit prices were left uncompared until the current basis matched.
Read the procurement brief, then send the package from the RFQ page.
A one-page requirement with family, contacts, pitch, current, voltage, termination, plating, ingress protection, quantity, US destination and timing. Mark unknown cells as open questions rather than guessed values. Optional budget needs a currency and a per-piece or whole-order basis. High-end, mid-range, budget or undecided is a preference, not a plant rating.
The desk sends the same brief to plants that can build the described interface. Each reply must name the exact model. A photograph of a similar shell is not interchange evidence. Host compatibility, code applicability and acceptance stay with the buyer and the proposed supplier.
Forwarding rate, wavelength, optical budget, receiver sensitivity, transmit power, dispersion, MIMO, channel width, gain and VSWR describe other equipment. Use them when the host RFQ has those lines. Do not let a connector quote absorb them. Insertion loss and return loss belong to the optical or RF path, not to a DC contact resistance stated in milliohms. Measurement accuracy of a contact-resistance meter is requested with the test record. Frequency range matters when the supplier claims a mixed power-and-signal insert.
No quotation file on this site supports a savings comparison. The useful step is to line up Incoterm, freight, duties, plating and test scope, then read the factory numbers on that shared basis.
An installed flange drawing often tracks the original shell family with fewer open dimensions. A second source remains quotable when contact diameter, plating thickness and the current-at-temperature cell match the drawing. Put the two offers on separate rows. Do not collapse them into one word that hides a plating change from gold to tin.
There is no file upload. Type one line per position: reference designator, family, current, voltage, termination, quantity and destination. Add the evidence you want attached, such as a contact drawing and a hipot note at 1500 VAC for 60 seconds if that test is relevant to your acceptance plan.
