Precision Centering Sensor for Macro-Style Measurement Cycles

The PA-21006V-TR is a high-precision centering sensor (measuring probe) designed for use with Macro-style reference systems. It is specifically intended for machine tool measurement cycles, enabling automatic workpiece or electrode centering, alignment verification, and in-process gauging.

Built on a 54×54mm reference base, this sensor seamlessly interfaces with Macro-style chucks, pallets, or centering plates, allowing it to be loaded into the machining cell just like any other electrode or workpiece. This enables fully automated measurement routines without manual intervention.

The probe features a stiff (rigid) design with a Ø3mm measuring ball, providing reliable contact for touch-trigger measurement cycles. The rigid construction ensures minimal deflection under measurement forces, contributing to high repeatability.

Manufactured from Stainless Steel 420 with a hardness of 32–36 HRC, the PA-21006V-TR offers excellent corrosion resistance and long-term dimensional stability, even in demanding EDM or machining environments.

Key Benefits:

• Automated Centering: Enables seamless integration into CNC measurement cycles, reducing setup time and eliminating manual alignment errors.

• Standardized Interface: 54×54mm reference base allows quick loading/unloading using existing Macro-style clamping systems.

• Rigid Construction: Stiff probe design ensures accurate measurement results with minimal deflection.

• Versatile Application: Suitable for workpiece and electrode centering, tool presetting, and in-process inspection.

• Durable Materials: Stainless steel construction resists wear and corrosion, ensuring long service life.

Typical Applications:

• Workpiece centering on machining centers or EDM machines

• Electrode alignment for sinker EDM

• In-process measurement cycles for quality control

• Automated tool presetting (when used with appropriate macros)

Compatibility: The PA-21006V-TR is designed for use with Macro-style chucks, pallets, and automation systems utilizing the industry-standard 54×54mm reference interface. It is suitable for machines equipped with measurement cycle capabilities.

Note: For optimal measurement accuracy, ensure that the reference base is clean and that the chuck/pallet system is properly calibrated. Consult your machine tool’s measurement cycle programming manual for integration details.
