Quote scope · modular jack
An rj45 keystone jack price is easy to misread when one factory prices a bare housing and another prices a housed jack, a shutter, a termination tool allowance, and a carton mark. LinkScope Sourcing 26 is an independent sourcing partner. This page is the comparison sheet a buyer can fill before factories reply. It is not a catalog of stock and it is not an authorization letter.
Start from the inquiry options if the name is already one of the three configurations, then bring the open fields here into the requirement desk.
Ask each proposed supplier to identify the exact manufacturer, model, and configuration. A matching “RJ45” word does not establish that two jacks share contact plating, shield fingers, or a rear IDC. Deviations belong on their own lines so a lower headline cannot hide a missing test report.
Housing polymer, color if it is specified, shielded shell or unshielded body, shutter, and the opening the jack must fit. State whether the quote is for the jack alone or for a loaded faceplate. Accessories such as blank modules, bezels, and icons are exclusions until someone adds them.
Punch-down on a 110-style tower and a toolless clamp change the tool the installer carries. A 4-pair 24 AWG cable is a different line from the jack, and measurement accuracy of a certifier is not a jack attribute. The jack price should say whether termination labor, a punch tool, or on-site support is inside the number. If labor is excluded, write that in the same sentence as the unit.
Quantity breaks, currency, Incoterm, freight, duties, and the lead-time clock (ex-works date versus arrival) need their own cells. A target budget, if you have one, states currency and whether it is per jack or for the whole order. Leave it blank when you want the factory number first.
Current datasheet, outline drawing, plating note, and the test method for insertion loss and return loss. If Power over Ethernet will cross the contacts, ask for the current and temperature-rise condition the supplier used. Do not treat a generic “PoE ready” phrase as a budget calculation.
| Quote field | What to demand in writing | Buyer review |
|---|---|---|
| Identity | Manufacturer, model, revision | Reject a family name standing in for a model |
| Contacts | 8P8C, plating thickness, mating-cycle statement if required | Compare microinches, not color of the housing |
| Electrical test | Frequency range, insertion loss, return loss, NEXT | Keep Cat6 and Cat6A rows apart |
| Delivery | Pack, inspection, destination, warranty route | Confirm who pays a failed incoming sample |
| Frequency range | 250 MHz or 500 MHz named with the category | Do not average the two into one cell |
| Impedance | Ask whether the sheet states about 100 ohms and under what condition | A round number without a method is a question |
| Plating | 50 microinches, about 1.27 micrometers, when the drawing uses that callout | Flash plate is a deviation |
| Power over Ethernet | 15.4 W, 30 W, 60 W, or 90 W as the clause to ask, plus contact current | An icon is not a watt budget |
| Connector mating cycle | The count on the model sheet, if your spec requires one | Leave blank when you have no requirement |
Category or the performance limit you will accept, shield, pinout, termination, opening, quantity, destination, and timing. Add conductor gauge and jacket only when cable is in the same purchase. Core count for a copper drop is typically four pairs; say so if the drawing is unusual. Bend radius is a cable-plant limit and should not be invented for the plastic housing.
Tooling, custom color, printed icons, shielded grounding hardware, test certificates per lot, expedited freight, and duty. A unit that looks inexpensive can omit the shield can and the continuity check. Write exclusions in the supplier’s words and keep them next to the price, not in a later email that never gets filed.
A compatible body may widen the supplier list when the drawing allows it. It may also conflict with a brand-specific panel or a warranty rule on the host system. Ask for fit on the named opening and for any marking the installer must see. This is a buyer choice between a specified brand and an alternate, not a claim that either one is already approved.
Switching capacity, optical wavelength, antenna gain, rack load, and UPS runtime are other product families. If the project needs them, open another line. Mixing them into an rj45 keystone jack price makes the comparison meaningless.
Paste the configuration, the exclusions, and the evidence list into the requirements box. The desk coordinates factory questions. It does not set the price and it does not hold the cartons. Optional supplier preference (high-end, mid-range, budget, or undecided) can travel with the note. It is not a score we have already verified.
Read the procurement brief if you want the longer field list before you submit. Quantity and destination still have to be yours. A blank destination stops the comparison, because freight and duty cannot be normalized.
