2.4 Automatic magnet strength adaptation
In order to improve signal quality and system compatibility, GB sensors are equipped with automatic gain control function. It can automatically adjust the signal amplification factor based on the magnetic field strength of the position magnet used, ensuring stable signal output throughout the entire measurement range. This simplifies on-site debugging and allows users to choose magnet types within a certain range.
2.5 Programmable measurement range
The starting and ending points of the sensor (i.e. zero and full range) can be programmed and modified through standard connecting cables after installation, without the need to remove the sensor or use a dedicated programmer. This provides great flexibility for adjusting the travel range on site.

Model and electrical interface configuration
The GB series offers three different electrical connection options to accommodate different installation and protection needs:
3.1 GB-N: M12 A coded circular connector (5-pin)
Connector model: M12 A code, straight head or elbow (specified when ordering).
Features: Industrial automation standard interface, easy to plug and unplug, protection level IP67 (when tightened correctly).
Recommended tightening torque: 0.6 Nm.
Working temperature: -30 ° C to+85 ° C.
Material: Nickel zinc alloy (GD Zn), contact plug made of brass.
Typical applications: General industrial environments that require quick connection/disconnection.
3.2 GB-K: M16 Circular Connector (6-pin)
Connector model: M16, straight head or elbow.
Features: More sturdy than M12, usually used for thicker cables or situations requiring higher mechanical strength.
Protection level: IP65/IP67 (when tightened correctly).
Tightening torque: 0.6 Nm.
Working temperature: -40 ° C to+100 ° C (straight head)/-40 ° C to+95 ° C (elbow).
Material: Nickel zinc plating.
Typical applications: heavy industry, hydraulic systems, mobile machinery.
3.3 GB-J: Direct cable lead out
Features: The sensor comes directly with a length of cable and cannot be disassembled. Provide the highest sealing reliability, suitable for long-term fixed installation and environments that are not easily pulled by external forces.
Protection level: IP65/IP67.
Cable type: optional PUR, Teflon or silicone sheath (see cable section below for details).
Typical application: Fixed equipment inside the control cabinet or that does not require frequent disassembly and assembly.
Analog output signal
The GB series provides standard analog current or voltage outputs for direct connection to PLCs, controllers, or display instruments.
Current output: 4-20 mA (two-wire or three wire system, depending on the model). It has the advantage of resisting long-distance transmission interference and is suitable for applications with long signal lines.
Voltage output: 0-10V or 0-5V (three wire system). Suitable for controllers with short distance and low impedance inputs.
The internal digital measurement values are converted into analog signals through a 16 bit D/A converter, ensuring high-resolution and smooth output characteristics. Users can set the output values corresponding to zero and full range using programming tools or on-site programmers, such as mapping 0-500 mm stroke to 4-20 mA.
Cable and programming tools
5.1 Standard Cable Options
When choosing the GB-J (cable outlet) version, the following three types of cables can be selected:
PUR cable (code H): Orange sheath, twisted pair with shielding, highly flexible. Suitable for conventional industrial environments, oil resistant and wear-resistant. The working temperature ranges from -30 ° C to+80 ° C.
Teflon cable (code T): Black Teflon sheath, twisted pair with shielding, flexible. It has an extremely wide temperature range (-100 ° C to+180 ° C) and is resistant to chemical corrosion. Suitable for extreme temperature or corrosive media environments.
Silicone cable (code V): Red silicone sheath, twisted pair with shielding, highly flexible. Temperature resistance range -50 ° C to+180 ° C, while maintaining excellent flexibility. Suitable for high temperature movement or situations that require frequent bending.
5.2 Programming Tools
The GB series supports two programming methods for setting parameters such as travel start point, end point, output direction, etc.:
Handheld programmer (part number 253 124): a portable device that connects to sensors through a connector and allows for intuitive "teach in" through buttons. Users only need to move the magnet to the desired starting and ending positions, and press the corresponding buttons to complete the programming. Very suitable for on-site single sensor debugging.
Control cabinet programmer (part number 253 408): can be permanently installed on a standard 35mm DIN rail with a "Program/Run" toggle switch. Suitable for applications that require frequent switching of travel ranges or batch configuration of sensors. This programmer can be connected to multiple sensors through a D-Sub interface.
In addition, MTS Sensors also provides a programming kit (part number 254 555), which includes an interface conversion box, power supply, multiple connection cables (M12, M16, terminal clips), and USB cables. Users can download configuration software for free from the official website and set parameters through a PC.
