The TOXU KC.CW.00498 is a 50 Ω micro-coaxial cable assembly for internal RF connections between compatible I-PEX MHF I receptacles.
Connectors: I-PEX MHF I plugs at both ends (20351-112R-37).
Cable: Gray 1.37 mm micro-coaxial cable.
Cable length: 165 ± 2 mm between connector cable-entry points.
Tape: 45 ± 3 mm of black acetate adhesive tape.
The TOXU KC.CW.00498 is a double-ended 50 Ω RF coaxial cable assembly for internal device wiring. It combines a gray 1.37 mm micro-coaxial cable with two I-PEX MHF I plugs. The dimensional drawing specifies the cable length and the position of the black acetate tape.
Matching Plug Configuration
Both ends are fitted with I-PEX MHF I plugs, part number 20351-112R-37.
Defined Cable Dimensions
The cable has a 1.37 mm outer diameter and measures 165 ± 2 mm between the connector cable-entry points.
Open- and Short-Circuit Testing
The finished-product drawing specifies 100% open- and short-circuit testing.

The drawing shows the two MHF I plugs, the cable length between their cable-entry points, and the placement of the black acetate tape. Use these reference points when checking cable routing and enclosure fit.

Internal RF links between boards with compatible MHF I receptacles
RF module connections inside electronic equipment
Internal antenna connections where both mating interfaces use MHF I receptacles
Verify the receptacle series on both devices before assembly. When planning the route, allow clearance for the plug bodies and confirm the cable path and tape position against the dimensional drawing.
For projects that also require antennas, RF connectors, or PCB assemblies, share your interface and enclosure requirements with TOXU so the components can be reviewed together.
This assembly is documented with connector part numbers, dimensional tolerances, and electrical inspection requirements to support engineering review and sourcing.
TOXU supplies RF cable assemblies, RF connectors, antennas, and PCB assembly services for OEM and system integration projects.
What connector is used at each end?
Both ends use the I-PEX MHF I plug, part number 20351-112R-37. Each plug mates with a compatible MHF I receptacle.
How is the 165 mm length measured?
The 165 ± 2 mm dimension is measured between the two connector cable-entry points indicated in the drawing.
Where is the black tape applied?
The tape starts 17.5 ± 3 mm from the left connector cable-entry point shown in the drawing and covers 45 ± 3 mm of cable.
