Product details

The Mitsubishi FX2N-20GM is a standalone 2-axis positioning module with open-collector pulse output at 200 kHz (100 kHz interpolation). It accepts DC 24 V ± 15% and runs as a smart peripheral or stand-alone controller.

Key ratings that decide fit

The CLR (clear) input range is DC 5 V to 24 V — common for 24 V PLC I/O or 5 V TTL-level encoders. The DOG (near-point dog) signal requires a pulse width of about 0.5 ms; the zero-point signal (PG 0) typical response is about 16 µs. These timing specs matter when replacing a failed module: if your machine relies on a faster or slower dog sensor, the position capture may shift.

Integration notes

Mounts on a DIN rail in the FX2N bus extension. Requires a dedicated Class D ground (100 Ω or less). Supply current is 10 W from the 24 V external supply; a 125 V, 1 A fuse protects the module. Input signals accept contact or NPN open-collector, 24 V nominal. The module cannot be used above 2000 m altitude without derating, and must not be installed in environments with corrosive gas, flammable gas, or excessive conductive dust.

Frequently asked questions

What is the CLR input voltage range?

The CLR (clear) input accepts DC 5 V to 24 V, typically used with a 24 V PLC output or a 5 V sensor.

How is the FX2N-20GM sourced given its EOL status?

Submit an RFQ for surplus/new-old-stock availability. Lead times typically run 1-10 working days subject to channel stock. No manufacturer commitment remains.
