GIS-40 Series Solid Shaft Incremental Rotary Encoder

About Incremental Encoder

Incremental rotary encoders generate an output signal each time the shaft rotates a certain angle. The number of signals (pulses) per turn defines the resolution of the device. 

Besides position tracking, incremental encoders are often used to determine velocity. The position in relation to the starting point can be calculated by counting the number of pulses. The velocity can be retrieved by dividing the number of pulses by the measured time interval.

An incremental encoder has at least 1 output signal “A” or typically 2 output signals, called “A” and “B”. These 2 signals are set up with a 90° offset, which is required for the detection of the encoder’s rotation. By turning the encoder clockwise, the “A” pulse is rising 90° ahead of the “B” pulse, by turning the shaft counterclockwise, the “B” pulse is rising ahead of the “A” pulse.

Additionally some incremental encoders output a “Z” signal. Once every rotation, this Z signal is rising for typically 90°, on the exact same position. This can be used as an accurate reference point.

Some incremental encoders also have additional differential signals, called “/A”, “/B” and “/Z”. These signals are inverted “A”, “B” and “Z” signals. Controllers can compare each pair (“A” must be equal to inverted “/A”) to ensure that there is no error during the transmission.

GIS-40 Series incremental encoder is  is an easy-to-install, incremental encoder with the options of NPN/PNP open collector, Push pull, Line Driver outputs and an extended resolution up to 10000ppr;

GIS-40 Incremental encoder is 38mm housing, small size encoder, it can manage the users install it in a limited space; The gearing of the encoder is from NMB, can enable the encoder movement smoothfully and long life.

GIS-40 Series incremental encoder can provide 1 singnal A, 2 singnals A/B, 3 singnals A/B/Z, and 6 singals A/B/Z/A-/B-/Z- for TTL(Line Driver Output), and also some customers aslo require 6singnals for HTL output(Push Pull)

Five steps let you know how to select your encoder:
1.If you’ve already used encoders with other brands, plz feel free to send us the information of the brand info and encoder info, like model no, etc, our engineer will advise you with our euqivalent replacement at a high cost performance;
2.If you want to find an encoder for your application, plz first select encoder type: 1) Incremental encoder 2) Absolute encoder 3) Draw Wire Sensors 4) Manual Pluse Generator
3. Choose your output format(NPN/PNP/LINE DRIVER/PUSH PULL for incremental encoder) or interfaces(Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP);
4. Select the resolution of the encoder, Max.50000ppr for Gertech incremental encoder, Max.29bits for Gertech Absolute Encoder;
5. Select the housing Dia and shaft dia. of the encoder; Gertecg is popular equivalent replacement for similar foreign products such as Sick/Heidenhain/Nemicon/Autonics/ Koyo/Omron/Baumer /Tamagawa/Hengstler /Trelectronic/Pepperl+Fuchs/Elco/Kuebler ,ETC.
