Trackball Mouse
Industrial 50mm Trackball Module KY-MS-MH50-BRS-A
KY-MS-MH50-BRS-A is an embedded mechanical trackball module built around a 50mm black resin ball at 400DPI resolution.
Product Overview
KY-MS-MH50-BRS-A is an embedded mechanical trackball module built around a 50mm black resin ball at 400DPI resolution. It gives accurate pointer control on consoles where a mouse cannot be used, and resists electromagnetic interference from nearby drives and instruments. Installation is embedded into the host panel with USB, RS232 or PS2 available.
- 50mm ball suits gloved and one-handed operation on fixed consoles where a mouse would slide
- 400DPI resolution gives predictable pointer movement for instrument and control software
- Wear-resistant resin ball keeps rolling smooth over a long service lifespan
- Good resistance to electromagnetic interference around industrial control equipment
- Embedded installation fits industrial, medical, marine and cabinet equipment fronts
- Supports external left, right and centre button control so panel buttons can be reused
Application Scenarios
- Measuring instrument consoles
- Industrial control equipment panels
- Medical equipment operator stations
- Marine and bridge equipment
- Cabinet mounted control terminals
Who It Is For
- Instrument and test equipment manufacturers
- Industrial control panel builders
- Medical equipment OEMs
- Marine equipment integrators
Problems It Solves
- A desk mouse has nowhere to sit on a vertical console, so the trackball is embedded in the panel
- Pointer jitter near drives and motors is countered by good electromagnetic interference resistance
- Soft balls wear and bind, so the module uses a wear-resistant resin ball
- Existing panel buttons can stay in use through external left, right and centre button control
Technical Features
- Embedded mechanical trackball construction
- Resolution 400DPI
- Black resin trackball of 50mm diameter
- Optional USB, RS232 or PS2 communication interfaces
- Low noise operation with fast response
- Support for external left, right and center button control

How It Compares
| Optical desk mice | An embedded 50mm ball works on vertical consoles and in vibration where a mouse cannot be placed |
|---|---|
| Smaller trackball modules | The 50mm ball is easier to control with gloves or wet hands |
| Modules with built-in buttons only | External left, right and centre button control lets the host panel keep its own switches |
Use Guide
- Cut the panel for the module body and mount the trackball from behind the fascia
- Wire external left, right and centre buttons if panel switches are used
- Select USB, RS232 or PS2 to match the host controller
- Remove and clean the resin ball periodically to keep rolling smooth
