The safety series of magnetic encoders supplied by TWK is expanded with the TBN/TRN-S4 series, which features increased resolution in the single-turn range (model TBN) and a variety of different applications. The series has been awarded SIL2 certification by TÜV, thus meeting the requirements for use in safety-related applications.

The resolution of the sensor system can be up to 16 bits. The detection of the multiturn part, the number of revolutions (maximum 12 bits), is performed by an absolute multiturn gear (model TRN). This model series can be used in areas that do not require extremely high standards for environmental influences and must be cost-Source: TWKeffective.

In addition to the safe position value, a safe speed signal is generated. The gate time can be varied to record the speed value; the default value is 100 ms. The gate time can be parameterized from 1 to 1000 ms depending on the requirements, thus enabling extensive use of the speed signal for slewing ring applications or time-relevant requirements. Mechanical variants available cover clamping flange with shaft design, blind shaft for preferably Ø 12 mm and various shaft diameters (Ø6, Ø10 or Ø12 mm).

The radial and axial shaft load is ≥ 250 N, and versions with a shock load of up to 500 g ±50 g can be implemented in separate variants for extreme industrial conditions. In addition to the version made of seawater-resistant aluminum, the housing can be supplied in a stainless-steel version (1.4305 or 1.4404) for special requirements such as offshore applications or requirements from the food industry.

The TBN/TRN-S4 series has protection class IP66 and can be used in a temperature range from -40° C to +85° C. For extreme requirements, the option of encapsulating the entire housing is available to meet the requirements of IP69K applications. The electromechanical interface can be designed as a cable output or connector output (M12 sensor plug).
