Cable fit
Check solid or stranded conductor, gauge range, insulation diameter, cable OD, shield termination, and strain relief before approving the jack.
Focused product range
Every catalogue keystone structure, mapped to its exact item codes.
Compare the supplied SUNPU catalogue photographs and model tables, then choose the jack around category, shielding, conductor range, cable diameter, termination method, rear clearance, mounting opening, and the complete copper-link basis.
System role
Modular RJ45 termination for work-area outlets, unloaded panels, consolidation points, and field-installation programs.

3 published item codesSelection framework
Four decisions to settle before the quotation.
Termination workflow
Compare punch-down, toolless, and coupler formats by tooling, pair management, closing force, rear depth, installer speed, and rework method.
Panel and faceplate fit
Confirm keystone opening, latch geometry, orientation, dust shutter, label access, adjacent-port clearance, and removal method.
OEM control
Lock housing color, markings, wiring label, packaging, included accessories, model code, and the sample used for repeat production.
Buyer questions
Resolve the details that change the order.
These answers help define the requirement. Final limits and evidence still depend on the exact quoted construction.
Is every keystone jack the same physical size?
No. The mounting concept is common, but body width, depth, latch geometry, shutter, label area, cable entry, and neighboring-port clearance can differ. Confirm the exact panel or faceplate opening.
Should a project use punch-down or toolless jacks?
Choose around conductor range, cable OD, termination volume, available tools, rear clearance, grounding, and installer practice. Both formats still require correct pair geometry and a defined installation method.
What changes for a shielded keystone jack?
The cable screen, jack body, panel or outlet, patch cord, rack bonding, and grounding design must form a planned pathway. Review each interface rather than treating the metal housing as sufficient by itself.
