Accessories
Signal connector
- mating housing: Molex 5016463600
- crimp terminals: Molex 5016471000
- crimp tool: Molex 638192300
Signal connector sealing
The controller's signal connector sealing is designed as a separate part to keep the controller dimensions as small as possible. It is installed on the signal connector cables (see drawing)
The product number for purchasing: igrid_seala.
The controller fulfills the environmental specification only if this sealing is properly installed.
AX Molex holder
This tool helps you to assemble an AX connector with the sealing. The AX Molex holder holds the Molex connector with the sealing, so you can easily insert wires with crimp.
You can download the model here: AX Molex holder and 3D print the holder.
Pre-crimped wires
siliXcon can provide pre-crimped wires for end-application prototyping. The bare wires with iGrid crimp on one end can be purchased by following ordering codes:
| Part name | description | wire color |
|---|---|---|
| Cable_i-grid_black_50 | Black cable, 0,25mm2, 50cm length | Black |
| Cable_i-grid_red_50 | Red cable, 0,25mm2, 50cm length | Red |
| Cable_i-grid_white_50 | White cable, 0,25mm2, 50cm length | White |

Mounting screws
- 4x M3 screw, you can choose between threaded hole in heatsink and oval hole without thread. Refer to the AX controller drawing.
- for through-hole mounting, minimum thread depth is 1.5 x screw diameter. Tightening torque depends on the material of the mounting base.
Thermal grease
- to improve cooling of the controller, you should apply thermal grease to the mounting area of the controller. Example: Electrolube HTC, AG termopasty HPX
