DC-DC Power Modules
Customized DC-DC Converters Explore DC-DC ConvertersUltra-long stroke measurement capability (up to 23 meters) is ideal for large hydraulic cylinders and long-travel industrial machinery.
Non-contact, wear-free magnetostrictive technology provides absolute position output and ensures long service life with minimal maintenance.
Flexible stainless steel hose design with minimum bending radius of 250 mm allows custom installation in confined or curved spaces.
Supports multiple output interfaces (Analog, SSI, Profibus-DP, CANopen, Profinet, EtherCAT, Start/Stop) for integration with modern industrial automation systems.
Rugged, fully enclosed construction with IP65/IP67 protection, high shock (100g) and vibration (20g) resistance, and wide operating temperature range (–40 °C to +85 °C) ensures reliable performance in harsh environments.

Installation and Use Instructions
Dimensions of RF flexible outer tube sensor
Option: Pressure-resistant outer pipe with flange, outer diameter 12mm/12.7mm
The flanged pressure-resistant outer pipe is used to cooperate with RF flexible sensor, which can withstand 35MPa pressure for hydraulic cylinder and provide protection for RF sensor. For large Cylinder, it is necessary to drill a φ18mm deep hole in the piston rod when selecting the pressure pipe with 12mm outer diameter, which can match our magnet ring with large inner diameter.
Installation instruction of RF flexible outer tube sensor
Two non-magnetic bolts are required for the installation of the sensor electronic bin. Long-stroke sensors need non-magnetic tube support (inner diameter ≥ 9.4), or bend into the desired shape. Sensors with hexagonal flanges can be easily mounted using non-magnetic bolts. Or you can choose a flanged pressure-resistant outer pipe with an outer diameter of 12mm, with a maximum stroke of 7620mm.
