Mitutoyo 12BAA303 Surface Roughness Gage Extension Cable

Product Description

The MITUTOYO 12BAA303 is an extension cable designed for use with the SJ-210 Surftest portable surface roughness tester. It extends the reach between the tester body and its detector, allowing technicians to position the instrument more flexibly during surface finish measurements. The cable measures 40 inches (1.00 meter) in overall length. Metrology technicians, quality control inspectors, and precision measurement professionals install this accessory to support accurate surface roughness data collection in shop floor and laboratory environments.

This extension cable is used in precision metrology applications where the standard cable length is insufficient for the measurement setup. Typical scenarios include surface finish testing on large workpieces, fixtures that restrict instrument placement, or setups where the tester display unit must be positioned away from the measurement point. It is intended for use specifically with the SJ-210 Surftest portable surface roughness tester in both light industrial and quality lab settings.

Compatible with the SJ-210 Surftest portable surface roughness tester.

Installation Notes

Installation is performed by metrology or QC technicians familiar with the SJ-210 instrument. Before connecting or disconnecting the extension cable, power down the tester to avoid signal errors or connector damage. Handle connector ends carefully to prevent pin damage, and do not force connections. Route the cable clear of moving machine parts or areas where it may be pinched during measurement operations.
