Eurorack parts

In order to manufacture low profile Eurorack modules vertical mount components are required. These allow the PCB to be mounted parallel to the front panel, keeping module depth to a minimum.

3.5 mm jack sockets

Vertical mounted potentiometer and two hacked to fit Kobiconn 16PJ138 panel mounting jack sockets in the Harvestman Piston Honda.

Vertical mount 3.5 mm jack sockets are hard to find. Options include:

• Cliff, used by Doepfer
• Erthenvar:3.5mm vertical mount jacks, switched
• Jalco YK21-5157 and variations. 10.5mm high versions and in mono, unthreaded bush
• Mouser:Kobiconn 16PJ138
• Farnell:Lumberg 1502 03 looks like a wired chassis socket with solder tags, it also has a PCB template
• QingPu, available from Thonk:
  • WQP-PJ3410, plastic bush
  • WQP-PJ3010BM, metal bush model with two ground lugs. PCB to panel gaps of 9.0 to 12.0 mm look feasible, with the lower values achieved by bending the four feet diagonally or at 90 degrees.
  • WQP-PJ301M-12, an alternative to Kobiconn 16PJ138, all PCB mount pins, with the reliable beryllium copper spring
• Rapid:TruConnect PJ-360, stereo, unthreaded bush

Potentiometers and controllers

Vertical mount potentiometers in the WMD Gamma Wave Source. The green one is a BI Technologies P0915N.

• Thonk:Alpha 9mm Pots
• Mouser:BI Technologies 10.5mm high linear pots
• Bourns:
  • PDB12-M, PCB mount, 9mm high, no thread, 12mm package
  • PTV09A-4
  • Farnell:3310Y series, 5mm deep with 6mm of thread so may be too low to be used easily
  • PTV111-3 7.5 mm high body with 5.0 mm high bushing, available with centre detent
  • Digital continuous encoders for microcontroller based products
• Vishay:
  • P12 series 11mm to panel
  • P9 vertical mount 7mm high with 7mm bushing, only up to 10V
