Absolute single-turn rotary encoder - 1

TWTC Document No.: TBA 15241 AE Date: 14.10.2019 ■ Redundant analogue single-turn rotary encoder ■ Robust design for rough applications, e.g. crane technology, construction maschines and plant engineering ■ Dual-chamber system for separating the rotor and electronics ■ Measuring ranges of the two redundant sensor units can be selected independently and can be configured by the customer. ■ Protection type IP 67 (higher protection types up to IP 69K possible) Design - Robust housing (wall thicknesses 5 mm) manufactured from seawater-proof aluminium (AlMgSi1) or stainless steel (material: 1.4305 optionally 1.4404). - Redundant voltage supply plus sensor system and electronics. - Shaft (measurement axis) with ball bearing, shaft seal and permanent magnet in prechamber. - Sensor circuit consisting of ASICs with Hall elements and interface electronics in sealed main chamber. - The contactless electromagnetic sensor systems are extended by a 12-bit D/A converter so that the measured variable is available as an analogue signal from 0 (4) to 20 mA or 0 to 10 VDC. Other outputs on request. - Electrical connections via 2x connectors M12x1. Function Apositive mechanical connection between the customer and sensor shaft ensures that the sensor shaft magnet precisely reflects the customer shaft's rotations. Two autonomously operating, redundant sensor units record the position of the magnet. A sensor unit consists of a sensor, an interpolator, a microcontroller and a D/A converter. The sensor units' redundancy offers the user two analogue output signals which are not influenced by each other. The so-called teach-in functionality enables the execution of functions such as zero point, end value, pre-set value and default value setting and enables the code direction to be changed independently for each channel. The zero point and end value setting functions allow the slope of the output signal to be changed. TWK-ELEKTRONIK GmbH Bismarckstraße 108 info@twk.de visit us at | twk.de

Absolute single-turn rotary encoder TBA redundant analogue Model: TBA58-KA360WR2SBxx Measuring range setting Standard measuring range Both redundant sensor units are set to a measuring range of 360° as default (characteristic curve 1). If a smaller measuring range is specified in the order number, both sensor units are synchronously set to this specified measuring range in the factory. Outside of the measuring range, the characteristic curves then have a symmetrically subdivided overflow and underflow (characteristic curve 2. Special characteristic curves, e.g. without overflow or...

SUPREME SENSORING TWTC Absolute single-turn rotary encoder TBA redundant analogue Model: TBA58-KA360WR2SBxxSetting option via multifunctional pins Setting option via multifunctional pins The measuring range, code direction, zero point, end value and pre-set value parameters and default value setting can be set by the user according to the circumstances at the application location. To do this, two multifunctional inputs (MFPs) are planned for each sensor unit. The input circuit for the MFPs is E1 (see next page). The analogue hand programming device model PMA-05 (see data sheet PMA11443) is...
