KN35 NPN PNP Ultra Thin Miniature Rotary Encoder

Ultra-thin miniature rotary encoder KN35 external diameter 35mm thickness 18mm


Product Description


Feather of S30 series encoder


    ● Encoder type: Incremental encoder

    ● External diameter: 30mm

    ● Shaft diameter: 4mm (D type)

    ● Environmental temperature: Operating temperature: -20~+80° (Non icing)

    ● Protection grade: IP50

    ● Cable length: 1000mm


Principle of encoder


      A logic gate interprets certain input voltages as high (logic 1) or low (logic 0).

TTL (transistor-transistor-logic): A signal above 2 V is interpreted as logic 1 and a signal less than 0.8 V is interpreted as logic 0. The output voltage ranges between 0-5 V.

      HTL (high-threshold-logic): A signal above 3 V is a logic 1 and a signal less than 1 V is a logic 0. The high output signal level is dependent from the supply voltage. Because of the higher voltage difference between logic 0 and 1, the HTL logic is more immune to interference and more resistant against electrical noise.

      Mechanical degree is the actual rotation of the shaft in degrees. Electrical degree is used for electrical signals. The required time for completing one alternating voltage/current cycle is defined as 360 electrical degrees (el°). For incremental encoders, one cycle is equal to one complete pulse. With a given PPR the electrical degree can be converted to mechanical degree for any incremental encoder.
