Description

A860-2120-T051

Introduction

Within the FANUC Series 800, the A860-2120-T051 is identified as a spindle sensor tailored for dependable performance in various industrial applications. This device is classified as an inductive sensor and functions efficiently at a voltage of 30 V DC. Connectivity is achieved through a cable, ensuring easy integration into existing systems.
The sensor's overall weight is recorded at 1 kg, indicating a lightweight design that does not compromise sturdiness. Its operating frequency ranges from 0 to 12 kHz, supporting diverse speed applications effectively. With a supply current specification of 6 mA, it provides reliable signal processing suitable for automation needs.
For mounting purposes, the sensor utilizes an M14 fitting, facilitating straightforward installation into compatible systems. Additionally, this unit is crafted from AIBZ material, known for its durability in industrial settings. It is equipped with a 4-foot cable, providing flexibility during installation.
Finally, the A860-2120-T051 holds an IP44 protection class rating, ensuring it is resistant to limited dust ingress and water splashes, providing longevity in tough environments.

System

The A860 series is FANUC's standard serial encoder family for servo and spindle motors in the FANUC αi and βi drive systems. Key characteristics of the series:
Compatibility: Direct plug-in replacement for older A860-2000 series (same mounting footprint).
Communication Protocol: Proprietary FANUC serial protocol (clock-synchronized, differential line driver).
Zero Battery Option: In absolute mode, uses a lithium battery (BR-2/3A or equivalent) on the drive side to retain position data after power-off.
System Integration: Works exclusively with FANUC CNC controllers (Series 0i, 30i, 31i, 32i, 35i) and FANUC servo amplifiers (αi-B, αi-C, βi-SV).


Application

A860-2120-T051

CNC Machine Tools (lathes, milling machines, machining centers):for spindle or servo motor position/speed feedback.
Industrial Robots (articulated arms, linear robots):joint angle feedback and homing sequence.
Automated Assembly Lines:conveyor indexing and pick-and-place positioning.
Semiconductor Manufacturing Equipment:high-precision wafer stage control.
Medical Imaging Systems (e.g., CT gantries):rotational position verification.
Printing & Packaging Machinery: synchronized multi-axis rotation.



FAQ

A860-2120-T051

1: Is this encoder absolute or incremental?
It supports both. In absolute mode, position is retained after power-off (requires a battery on the drive). In incremental mode, it behaves as a standard A/B/Z-phase encoder via serial data.

2: What battery does it require for absolute operation?
The encoder itself has no battery. The backup battery (typically FANUC BR-2/3A 3V lithium) is connected to the servo amplifier’s battery port. Replace every 1-2 years depending on usage.

3: Can I replace an A860-2020-T051 with this A860-2120-T051?
Yes, they are functionally identical in electrical and mechanical form. The "2120" indicates a later production revision with improved sealing and temperature range. Always confirm the mounting shaft diameter (standard 6mm or 8mm) matches your motor.

4: What does error code “SV0459” mean on my FANUC controller?
This indicates the encoder serial signal is not being received. Common causes: broken cable, loose connector at JF1/JF2, damaged encoder due to over-speed (>6000 rpm), or electrical noise. Check cable continuity and shielding.
