Front panel options
The Makersan datasheet lists these layouts for the front panel of the MO 387 grip: 0 to 5 push buttons, a horizontal or vertical (left or right) thumbwheel, two thumbwheels, and a micro joystick with or without push buttons. The EHR Elektronik version on this page uses a right vertical thumbwheel with two push buttons; the rear carries a push button and a presence detection switch.
Additional datasheet information
- The CAN protocol is listed as SAE J1939 or CANopen; the version on this page is CANopen.
- The datasheet lists two different centering spring forces for the lever.
Operation and safety notes
Warnings from the Makersan order sheet:
- If a spring breaks, the joystick must not be used with the remaining springs.
- A joystick that has been exposed to shock or impact, or has fallen, must be scrapped and not used again.
- The safety instructions in the base and grip datasheet must be respected, and the vehicle manufacturer should take the failure modes in the datasheet into account.
The Makersan joystick family
Alongside the MO 391 & 387, the same manufacturer’s MO 395 mini and MO 377 fingertip joysticks are offered in EHR Elektronik versions. The table compares the versions on these pages.
| Model | Axes | Output | Connection | Protection |
|---|---|---|---|---|
| MO 391 & 387 | 2 axes (full) | CANopen | Deutsch 8-pin | IP67 |
| MO 395 | 2 axes (full) | CANopen | Deutsch DTM04-4P, 15 cm cable | IP65 |
| MO 377 | Single axis | Analog 0.5V – 4.5V | 250 mm loose cable (AWG 24) | IP6K9K / IP54 |
For all products see the Makersan page or the joysticks category.
MO 391 & 387 Midi CANopen Joystick – Datasheet (PDF)Frequently asked questions
Is there a J1939 version of the MO 391 & 387?
The Makersan datasheet lists the CAN protocol as SAE J1939 or CANopen. The EHR Elektronik version on this page is CANopen, with Node ID 4 (04h) and a default of 250 kbit/s. If you need another protocol, please contact us.
How is redundancy achieved?
Measurement uses a contactless hall-effect principle and is described as full redundant in the datasheet. The version on this page has 2 axes (full).
Can the front panel and button layout be changed?
The front panel is interchangeable. The datasheet lists layouts with 0 to 5 push buttons, thumbwheels and micro joystick options; the version on this page has a right vertical thumbwheel with two push buttons. Please contact us for a different layout.
What should be observed during use?
If a spring breaks, the joystick must not be used with the remaining springs; a joystick that was exposed to shock or impact, or has fallen, must be scrapped. Details are in the safety notes above and in the datasheet.
