GB Type Displacement Sensor
These compact sealing stainless steel position sensors are specifically designed for hydraulic cylinder installation applications, particularly suitable for U-type head hydraulic cylinders or those with space constraints.
For the widely used standard hydraulic cylinders, the GB type sensor is an excellent choice. A magnetostrictive position sensor, combined with a high-quality cylinder body and control valve, forms a drive system that can meet the technically high standards of the processing industry.
The GB type sensor provides analog current and voltage outputs, as well as forward and reverse measurement functions. The analog output signal is proportional to the magnet's position. The measurement range is factory-set and does not require recalibration. Since it is a direct output, no additional signal conversion circuit is needed when connecting to a controller or meter.

GB Type Shell Dimensions and Installation Instructions
Easily installed in any location, with minimal installation space required.
The pressure-resistant stainless steel round tube with an installation flange is secured through the threaded holes of the electronic head with 6 M6*16* A2-70 (ISO4762) screws. A tight seal is achieved using a 15*2 O-ring and a fixing ring.
Hydraulic Installation Diagram Examples
A rod sleeve (such as Teflon) is used to prevent friction between the magnet and the sensor rod. The hole in the piston rod depends on hydraulics and speed, etc. The hole diameter must not be less than 13mm and not exceed the peak pressure of 700bar.
Positioning Magnet
To measure position, secure the magnet using non-magnetic mounting devices (screws, supports, etc.). When the carrier is made of ferromagnetic material, be mindful to use a non-magnetic washer of 5mm thickness and non-magnetic screws for the magnet installation. Note the small installation dimensions shown in the illustration on the right.
Sensor wiring method
When mating aviation connectors, define by pin and corresponding wire color.

Note:
If there's a risk of damaging the straight-through cable during installation, please opt for the connector connection method. The electronic part of the sensor and the straight-through cable are both completely embedded and fixed in the electronic head disc, making repairs to the electronic module difficult. If an issue arises, the entire sensor must be replaced.
