Interpretation of Ordering Code

The ordering code for the GB series consists of multiple fields, with the following example format:

GB – N – 0100 – A – 0 – 4 – H – M – 000

Meaning of each field:

GB: Product Series (GB Series)

N: Electrical interface (N=M12; K=M16; J=cable)

0100: Measurement range (unit: mm, for example, 0100 represents 100 mm)

A: Output type (A=4-20 mA, V=0-10 V, etc.)

0: Output direction (0=positive direction, 1=negative direction)

4: Resolution/Filter Settings

H: Cable options (only valid for J version, H=PUR, T=Teflon, V=Silicone)

M: Position magnet type (M=standard ring magnet, other codes correspond to different magnets)

000: Special options (such as high temperature, ATEX, etc.)

Users need to select each item according to their application requirements, referring to the selection table in the data manual, to ensure that the sensor matches the threaded interface, stroke length, and electrical interface of the hydraulic cylinder.

Application Fields and Advantages

8.1 Hydraulic cylinder position feedback

The most common application of the GB series is to install it inside hydraulic cylinders and measure the absolute position of the piston. This can be used for:

Servo hydraulic control: closed-loop control of valve core position or cylinder speed to achieve high-precision motion.

Injection molding machine: Control the position of the injection screw and locking cylinder.

Press: Real time feedback of slider position to ensure consistent pressing depth.

Wind power generation: blade angle feedback of the variable pitch system hydraulic cylinder.

8.2 Valve actuator

The flat and compact electronic head and lateral outlet make the GB sensor very suitable for installation inside valve actuators (such as pneumatic, hydraulic, or electric actuators). The sensor rod is connected to the valve stem, which can accurately feedback the opening of the valve for process regulation or safety interlocking.

8.3 Mobile Machinery and Construction Machinery

For mobile devices such as excavators and loaders, GB sensors are vibration resistant, impact resistant, and have a high sealing level. They can be installed inside the oil cylinder to monitor the position of actuators such as the boom and bucket, achieving intelligent control and collision prevention functions.

8.4 Energy and Power Generation

High reliability position feedback is required in valve control of steam turbines, water turbines, and gas turbines. The high temperature option (+100 ° C) and high-pressure resistant rod of the GB sensor enable it to adapt to hot oil and high-pressure environments.

Installation precautions

Sealing and threading: When connecting the sensor rod to the cylinder body, a suitable O-ring or sealing gasket should be used to prevent hydraulic oil leakage. The tightening torque of threads should follow the manufacturer's guidelines.

Magnet installation: The position magnet must be installed on the piston and concentric with the sensor rod. The polarity direction of the magnet should be correct to avoid direct contact with the rod (non-contact requirement).

Cable wiring: Signal cables should be routed separately from power cables to avoid electromagnetic interference. Suggest using shielded cables and grounding the shielding layer at one end.

Programming sequence: After installing the sensor, power on and check if the output signal is normal before programming the travel range. When programming, the magnet needs to be moved to the actual mechanical limit.

Environmental temperature: If the application temperature exceeds+85 ° C, the high temperature option (-400C) must be selected, and good heat dissipation of the electronic head must be ensured.
