• Detection of damage on microdiameter tool. Detects a break, chip,
or excess swarf from the variation of light quantity received
(Fig. 2.126).
Metal/steel/nonferrous industries:

• Detection of misfeeding in high-speed press. The noncontact
laser sensor, timed by a cam in the press, confirms the mate-
rial feed by monitoring the pilot holes and then outputs the
result to an external digital meter relay (Fig. 2.127).
• Simultaneous measurement of outer diameter and eccentricity of
ferrite core. Simultaneously measures the outer diameter
and eccentricity of a ferrite core with a single sensor system.
The two measured values can then be simultaneously dis-
played on a single controller unit (Fig. 2.128).
