Features

TM26D is a two-signal model with overtravel (OT) signal

This tool setter model is equipped with an OT signal, independent from the measurement signal, and is output before the operating limit of the sensor is exceeded.
This feature prevents accidents that could damage equipment and sensors due to collisions.

Repeatability of 1μm and coolant-resistant IP67 protection rating spec.

It performs speedy and automatic tool measurement before starting machining and in-machine tool compensation during the machining cycle. The IP67 rating ensures high-precision detection even in adverse environments where coolant is applied, contributing to time savings in tool setting.

High reliability + Low cost: Fewer false detection achieved by touch sensor method

Since the detection is made by direct contact with the tool’s leading edge, false detection due to coolant splatter or mist is less likely to occur than with expensive non-contact sensors (e.g., laser sensors), thus ensuring stable detection.
