Design Criteria
Configuration
Grounding
Wiring Terminations
Due to the jumper blocks capability provided, the switching
configurations available per jack channel are:
• Half Normalled Bottom Row
• Full Normalled
• Parallel
• Isolated
The TB Panel is delivered in a full normalled configuration
for each jack channel. A non-configurable half normalled
("-HN") bottom row version with solder lugs is also avail-
able.
NOTE: Take care when handling digital signals. Do not use
Parallel configuration and avoid other parallel paths with
Half / Double Normalled configurations. Parallel paths may
lead to mismatching.
The flexible grounding system allows four possibilities to fit your needs:
• Individual: Each channel ground is separately connected with the corresponding cable shield (default configuration).
• Group: Some channel grounds are PCB connected by making soldering joints on the PCB and by cutting tracks
respectively to form a group that is connected to one common cable shield.
• Central: All channel grounds are PCB connected by making soldering joints and wired with only one cable shield.
• Chassis-Common: Same as central grounding with additional connection of the common ground to the Patch
Panel chassis by means of a jumper.
TB patch panels are available with:
• Spring loaded push terminals (NPP-TB)
• Solder lugs (NPP-TB-HN)
The spring loaded terminal blocks are fast and easy to connect and disconnect the wires.
No soldering and screwing necessary. Simply insert the stripped wire after pressing down the white key.
Accommodates stranded wires up to AWG 20 (0.5 mm
2
) and solid wires up to AWG 18 (0.75 mm
2
).
The NPP-TB patch panels are equipped with gold plated,
high quality long life NJ6TB-V Jacks for BPO/MIL style
plugs. The panels are easily programmable for six switching
configurations and offer a flexible grounding system.
The NPP-TB patch panels are very robust and compactly
designed for 19" rack mount (19" x 1U) with galvanized
metal housing and a built-in cable bar on the rear for
securing wires. There is a rear extension bar (NPP-S)
available as an option. On the front side there is an
attractive additional lettering area for each channel pair
with a marking strip and individual snap-on colour coding
plates.
