Cassette-Type Contact Displacement Sensor

DHGT-H Series

DHGT-H Series

The Cassette-Type Contact Displacement Sensor is a high-performance sensor developed by DH-Robotics for industrial precision measurement and displacement detection applications.

The sensor adopts sealed absolute-position optical grating encoding technology, enabling highly accurate and stable displacement measurement across the entire measuring range.

With a robust mechanical structure and IP67 protection rating, the sensor effectively withstands oil, dust, and coolant splashes commonly found in industrial environments. This ensures long-term measurement stability and reliability during continuous operation.
It is widely used in automation equipment, precision assembly, and inline inspection applications.
