SANJUKS V6-ST

01. Lower-Profile Base

According to the product listing, the actuator area is 1.6 mm lower and the lower housing is 3 mm lower. These changes provide more clearance in smaller cases. Before installation, check the available space for the lower shaft, terminals, and wiring as well.

02. Adjusted Microswitch Positions

The switch mounting positions have been adjusted to slightly reduce the lever’s operating range. This refines the actuation positions and feel. The difference you feel can vary with the grommet and component combination.

03. Separable Upper and Lower Housing

The upper section attached to the mounting plate can be separated from the lower section holding the switches, making grommet replacement and internal component inspection easier. Disconnect power before disassembly and record the order of the screws and components.

The upper and lower sections are shown separated. Note the positions of the mounting screws and internal components as you work.

04. Aluminum Upper Housing

The upper housing is made of aluminum, improving its construction and finish. The photo shows the metal housing and low-profile collar structure.

05. Grommet Inspection Window

The lower housing includes a slotted window for checking the color of the internal grommet. It lets you identify the installed grommet’s color from the outside.

The small inspection window underneath reveals the color of the internal grommet.

Samducksa 20-Tension Grommet

The standard grommet is a yellow Samducksa 20-tension grommet. The product listing describes the feel as soft. Perceived resistance and return-to-center feel may vary by user and assembly condition.

Omron Microswitches

Four Omron V-16-3C26 switches register the directional inputs. The photo shows the switch and actuator positions and the orientation of the terminals.

Bolt-Retained Shaft and Dedicated Actuator

A 9 mm anodized aluminum shaft and a 15.2 mm actuator designed for the V6-ST are used. The lower assembly is secured with a bolt, so check the order and fastening of the bolt and washers during disassembly and reassembly.

The central actuator and lower retaining bolt are visible here.

Height Reductions Apply to Different Parts

The specified 1.6 mm and 3 mm reductions apply to different parts. Do not add them together as an overall height reduction. Compare the actual lever and case to confirm clearance.

Prepare an Adapter Harness for 5-Pin Wiring

If your existing arcade stick uses a 5-pin connector, a 5-pin-to-8-pin adapter harness with .187 connectors is required. Check the switch terminals and PCB pinout, and identify the common ground and directional signal wires before connecting.

Included Components

Check Which Way Actuator Compatibility Applies

The ST actuator can be used in V6 and V6-2 models. This does not mean that all V6 or V6-2 actuators can be used in the V6-ST. Check the dedicated V6-ST specifications when choosing a replacement.

When Replacing the Grommet

Disconnect power and USB before separating the housing. Record the grommet and bobbin orientation and the positions of the mounting screws. After replacement, make sure the grommet is seated correctly, then test every direction and the return to neutral.

Start with the Standard Setup

First, get familiar with the resistance, return-to-center feel, and diagonal inputs provided by the Samducksa 20-tension grommet. Changing one component at a time makes it easier to identify differences in feel.

STEP 01

Disconnect Power and Record the Existing Setup

Disconnect USB and power before opening the case. Take photos of the existing lever orientation, wiring, and mounting screw positions to help with reassembly.

STEP 02

Check the Plate and Lower Clearance

Compare the V6-ST mounting holes with those in your case. Before securing the lever, make sure the low-profile collar does not interfere with the panel and that there is enough room for the lower shaft, switch terminals, and wiring.

STEP 03

Check the Grip and Lower Retaining Bolt

Secure the grip so it does not loosen, and check the assembly of the actuator, lower bolt, and washers. The lower assembly uses bolt retention, so check the orientation and fastening of each part.

STEP 04

Connect the Wiring and Test Every Direction

Connect the wiring without pulling or pinching it. Keep your hands and tools clear of the interior, then reconnect power. On an input test screen, check up, down, left, right, diagonals, and neutral. Once everything works correctly, disconnect power again and close the bottom panel.

If Directions Are Reversed

Disconnect power, then check your reference photos and the PCB pinout. Identify the common ground and directional signal wires; do not rely on wire colors alone.
