详情描述


The MH magnetostrictive displacement sensor can be used unrestrictedly on multi-functional walking machinery and can replace contact-type linear sensors such as potentiometers. In high-dynamic systems, BRSEN@ sensors can be used for safety control, thereby enhancing productivity, availability, and work quality during the machine's operation. The sensors are insensitive to vibrations, shocks, dust, weather conditions, and electromagnetic interference. The MH series sensors have been successfully applied in steering cylinders for front axles and articulated frames, hydraulic jacks, and hydraulic steering systems in agricultural and construction machinery.


Simple mechanical structure


This sensor is sturdy and durable, consisting of the following main components:


① The innovative connector system can be installed in just seconds, offering great convenience without the need for welding or crimping, and boasts dust and waterproof ratings up to IP69K.


② The flange housing is equipped with an internal electronic device and a signal converter.


③ The position magnet, as a moving part, can be mounted at the bottom of the piston. This magnet is designed to move along the pressure tube, without contacting the pressure-resistant outer tube and without wear, allowing for the measurement of the actual position.


④ The pressure-resistant outer tube is placed within the bored piston rod, containing a protected magnetostrictive inductive element.

The MH CAN-bus Linear Position Sensor, functioning as a slave station, complies with the Canbus (ISO 11898) protocol standard. The sensor directly converts position data into bus-oriented data and sends it to the controller. The bus interface is suitable for transmission rates below 1 Mbps. The software integrated in the sensor supports highly customizable CANopen sensor bus systems.


Pressure-resistant outer tube dimensions and installation instructions


MH Series pressure-resistant outer casing, stainless steel electronic storage, designed specifically for hydraulic system use, integrated within the hydraulic cylinder, capable of withstanding pressure up to 35MPa continuously (70MPa peak).

Installation Precautions:


Cut all sensor connections during welding!


Do not connect the grounding terminal to the piston rod or the cylinder bottom.


If sensors are installed inside the cylinder, do not weld any part of the cylinder.


If there are sensors inside the cylinder, do not weld near the cylinder.


Any part of the welding machine that comes into contact may produce current or voltage, due to the lubrication of the insulation bearing or the sliding parts of the plastic components. In such cases, the same consequences may arise.


Installation Instructions:


Install sensor housing with M5 DIN913 flat-head screws. The sensor can only be fixed in the direction of the shaft, as the screws can only contact the housing. The maximum torque on the screws is 1Nm, otherwise the sensor housing may be damaged. Additionally, apply sealant (such as Loctite Blue) to the fixed sleeve screws after installation.
