Component Specifications

Definition
A Position Reference Mark is a calibrated physical feature or indicator on a rotary base that serves as a precise datum point for establishing angular position, alignment verification, and repeatable positioning during machine setup, operation, and maintenance. It ensures consistent reference across rotational cycles.
Working Principle
The mark provides a fixed, known reference point on the rotating element. By aligning sensors, tools, or visual indicators with this mark, the system can determine absolute angular position, synchronize operations, and maintain positional accuracy through mechanical indexing or electronic detection.
Materials
Typically made from durable materials: hardened steel (AISI 4140/4340), stainless steel (304/316), anodized aluminum, or ceramic coatings for wear resistance. Surface often includes laser-etched or engraved markings.
Technical Parameters
  • Diameter 5-50 mm
  • Mounting Threaded, adhesive, or press-fit
  • Tolerance ±0.05° angular, ±0.1 mm positional
  • Environmental Rating IP65/IP67 for dust/water resistance
  • Operating Temperature -20°C to 120°C
Standards
ISO 9283, ISO 230-1, DIN 55027
