Product Overview – KH53 SICK
The KH53 (POMUX) is SICK’s non-contact absolute linear encoder system designed for absolute length measurement up to 1,700 meters. The system consists of a read head and measuring elements installed along the measuring path. Utilizing non-contact magnetic technology, the KH53 delivers robust performance in environments with heavy dust, strong vibration, and high shock. It is ideal for container cranes, automated storage/retrieval systems (AS/RS), rail-guided vehicles at ports, and steel plants in Vietnam.
Key Highlights:
- Measuring length: 0 – 1,700 m (depending on version)
- System resolution: 0.1 mm
- Repeatability: 0.3 mm (KH53) / 1 mm (KH53 Advanced)
- Interfaces: SSI (24-bit Gray code) / PROFIBUS DP
- Distance between read head and measuring element: 25 mm ±10 mm (KH53) / 55 mm ±20 mm (KH53 Advanced)
