Industrial Wireless MPG Pendant for Fanuc CNC Controls

Setting datums, touching off tools, and indicating parts means fighting a 3-metre spring cable at the front console. Our Industrial Wireless MPG is a drop-in replacement that interfaces with Fanuc I/O units at the electrical hardware layer, with zero ladder modifications.

Fanuc handwheel electrical specifications

What the receiver presents on the Fanuc side of the connector, matched to the parameters the control already expects.

  • Pulse train: 100 Pulses Per Revolution (PPR) optical encoder. Standard 4-state quadrature cycle matching Fanuc parameter 7110/7117 multiplier settings.
  • Signal logic: 5V DC single-ended pulse output: HA (Phase A) and HB (Phase B), each referenced to a common 0V line, matching Fanuc's standard JA3 manual pulse generator interface.
  • Power supply: Regulated +5V DC drawn directly from the Fanuc I/O unit or operator panel terminal.
  • Safety circuit: Dual-channel NC dry relay wired directly into Fanuc's *ESP (Emergency Stop) string. Drops within 100 ms on RF link loss.
