Buyer guide
How to Specify a Replacement MPG
Most MPGs look alike from the front, but the electrical details must match your control. Before ordering, check these points on the old unit or in the machine manual:
- Supply voltage: 5V DC and 12V DC are the most common. A 5V unit on a 12V supply can be damaged, and a 12V unit on 5V may not output reliably.
- Pulses per revolution: typically 25 or 100. A mismatch changes how far the axis moves for each click.
- Output type: line driver (A, A-, B, B-) or voltage/open-collector output (A, B). The control input must suit the output type.
- Mounting: panel diameter (for example 60 mm or 80 mm), mounting holes and depth behind the panel.
- Pendant details: number of axes on the selector, multiplier switch, emergency stop, enable button, cable length and connector.
A photo of the label and the wiring terminals usually lets us identify a direct replacement.
Common MPG Faults and Quick Checks
- Axis does not move: check that the control is in handle mode, the correct axis is selected, and the supply voltage is present at the MPG terminals.
- Axis moves the wrong way or jumps: phase A and B wiring may be swapped or a signal wire may be loose. Interference from nearby power cables can also cause erratic moves.
- Missed or extra steps: often caused by worn detents, contamination inside the encoder, or a pulse-count mismatch with the control parameter.
- Pendant works intermittently: look for broken cores in the coiled cable near the connector, a common wear point.
If checks point to the handwheel itself, replacement is usually quicker and cheaper than repair.

Buyer questions
Frequently Asked Questions
What is the difference between a 25-pulse and a 100-pulse MPG?
It is the number of pulses the handwheel sends per full turn. Most handwheels have 100 detent clicks per turn, so a 100-pulse unit gives one pulse per click. The control's parameters are set for a particular count, so fit a replacement with the same pulse count unless you also change the parameter.
Can I replace a 5V MPG with a 12V one?
Only if the control input and supply are suited to 12V. Supplying a 5V MPG with 12V can damage it, and a 12V MPG on a 5V supply may give weak or missing signals. Check the label on the old unit or measure the supply at the terminals before ordering.
Do you supply Tosoku manual pulse generators?
Yes, Tosoku HC series manual pulse generators are listed in our catalogue, along with compatible MPG handwheels from other makers. Send the model number from the label, or a photo of it, and we will confirm availability, condition options and price.
Will a handheld pendant MPG work on my machine?
Usually yes, if the control has MPG and axis-select inputs available. A pendant needs extra wiring for the axis selector, multiplier switch and, on many models, an emergency stop. Share your control model and the current wiring and we can suggest a suitable pendant.
Are wireless MPGs reliable on the shop floor?
Wireless pendants remove the cable, which is the most common wear point, but they need a receiver wired into the control and a charged battery. They suit large machines and routers where the operator moves around. Confirm the receiver interface matches your control before ordering.
Why does my axis jump or move erratically when I turn the handwheel?
Common causes are a loose or broken signal wire, swapped A and B phases, interference from nearby power cables, or a worn encoder inside the handwheel. Check the wiring and shielding first. If the fault stays with the handwheel when tested on another machine, it needs replacing.
How do I get a quote for an MPG?
Send the part number or a clear photo of the label, the supply voltage, pulse count and connector type through our quote form, phone or email. We will check compatibility and reply with price and availability.
