SENC 150 Linear Encoder

The SENC 150 is Acu-Rite's ball-bearing guided linear encoder, the scale that reads position for DRO systems on knee mills, lathes, and surface grinders. It isn't limited to Acu-Rite display units; it retrofits onto any DRO system built to accept a TTL-output linear scale. Select your resolution and travel length above. This unit ships direct from Acu-Rite OEM stock. A drifting or failed scale means the readout can't be trusted and neither can the part coming off the machine.

Ordering Information ▼

Ordered By Travel Length, Not Overall Length

The travel length you select above is the measuring length — not the physical length of the scale housing.

Overall Length Formula

Overall length = travel length + 6.362″ (161.6 mm). Example: a 28″ travel unit has a 34.362″ overall housing length.

Important Information ▼

Confirm Resolution Before Ordering

Match resolution to what your DRO or control expects. A mismatched resolution will not read correctly once installed.
