Description
📌 FANUC A20B‑2100‑0270 — Description
Part Number: A20B‑2100‑0270
Type: Position Detector Interface PCB (printed circuit board) used in FANUC CNC control systems.
Series: A20B‑2100 family of I/O and interface boards.
🧩 Function & Purpose
The A20B‑2100‑0270 is a 4‑axis position detector interface board. It provides an interface for up to four basic axis position detectors (encoders/sensors) within a FANUC CNC system, enabling the controller to receive and process feedback signals from those detectors for motion control and positioning tasks.
It’s typically installed inside the CNC control cabinet or rack, where it connects sensor feedback lines from machine axes to the controller’s internal electronics.
🛠 Typical Usage
-
Axis Feedback Interface: Handles signals from position detectors for up to four axes of a machine.
-
Precision Motion Control: Used where accurate position feedback is essential (e.g., milling machines, lathes, machining centers).
-
Modular CNC Hardware: Fits within the modular PCB architecture of FANUC controls alongside other I/O, operator panel, and expansion boards.
