Data sheet No.: TBA/TRA 14269 DE Date: 18.04.2019 ■ Robust design for harsh applications e. g. cranes and construction machinery ■ Magnetic Sensor system(s) ■ Measuring ranges TBA: 360° (4096 revolutions x 360°) ■ Mrotection grade IP 65/ IP67 (IP 69K option) ■ MRA Option: Redundant design (Data sheet - TRA 12665) Design - Robust housing (Wall thickness max. 5 mm) manufactured from seawater-proof aluminium (AlMgSi1 -3.2315) or stainless steel (Material: 1.4305 or 1.4404). - Shaft fitted with ball bearings bears the magnet for recording the angular position and the drive gear of the multiturn transmission for absolute revolution counting - Design form in 0 42, 0 50, 0 58 mm diameter and customer specific applications - Magnetic sensor system(s) for position measurement - Signal output via 12-Bit D/A converter Analogue Signal outputs: 0 (4) to 20 mA, 0 to 10 VDC or ± 10 VDC available. - Electrical connection via connector M12x1 or via cable Function The rotary encoder has an analogue interface. The D/A converter has a resolution of 12 bits, which are distributed over the maximum measuring range of 360° (TBA) or 360° x 4096 revolutions (TRA). The sensor TBA has a measuring range of 360 degrees, that means one turn. The encoder TRA provides additionally the revolutions (max. 4096) absolute with a gear. The standard values are 360° at TBA and 1,474,560° (360° x 4096 revolutions) at TRA. The output signal can be parameterised and referenced via Teach-in by means of two multifunction pins (MFP). For both sensors TBA and TRA the Teach-in functionality is integrated. Via the Teach-in functions following parameters can be changed: Set zero point, set final value, set Preset value (middle of the measuring range), code sense (CW or CCW) and also the setting of the default values. With the functions set zero point and set final value the gradient of the signal output can be changed. TWK-ELEKTRONIK GmbH BismarckstraBe 108 info@twk.de visit us at | twk.de
