LinkHigh-Precision Non-Contact Reference Point and Limit Switch System
The Magnescale SET-P15 and SET-P16 Magneswitch systems provide highly reliable non-contact reference point detection for Digiruler measurement systems and industrial automation applications. Combining a magnetic sensor with a precision magnet, these systems deliver exceptional repeatability, long service life and reliable operation in harsh industrial environments.
The SET-P15 consists of a PK15 sensor and PG104 magnet, while the SET-P16 combines a PK16 sensor with the same PG104 magnet. Both systems are designed to withstand oil, dust, vibration and mechanical shock, making them ideal for machine tools, automation equipment and precision positioning applications.
Key features
- Exceptional Repeatability – Provides repeatability of ±3 µm under controlled conditions, ensuring highly accurate reference point detection.
- Non-Contact Operation – Magnetic sensing technology eliminates mechanical wear, resulting in long-term reliability and minimal maintenance.
- Harsh Environment Capability – Designed to withstand oil, dust, vibration and impact commonly found in industrial manufacturing environments.
- High-Speed Detection – Supports response frequencies up to 10 kHz for fast-moving machinery and positioning systems.
- Visual Status Indication – Integrated LED indication provides immediate visual confirmation of switching operation.
- Compact Design – Small sensor and magnet assembly allows easy integration into new and existing machinery.

SET-P15 vs SET-P16
SET-P15 (PK15 Sensor + PG104 Magnet)
The SET-P15 can be used as:
