# Through Bore Encoder V2

The REV Through Bore Encoder V2 provides precise, reliable shaft position measurement with both incremental (ABI quadrature) and absolute (pulse-width) outputs

The Through Bore Encoder V2 delivers higher measurement accuracy—up to ±0.5°—while maintaining strong performance in environments where dust or debris may affect optical encoders. The magnetic sensing design offers consistent feedback without the need for complex alignment or maintenance.

{% hint style="warning" %}
The FTC Control System currently only supports Incremental Encoder input through the motor encoder ports. Absolute pulse input is not supported.
{% endhint %}

{% hint style="danger" %}
**Do not disassemble the sensor.** Disassembling the Through Bore Encoder will dereference the zero position with the physical case notch. It is not possible to recalibrate the zero position as it is permanently saved inside the sensor at the factory
