Product Description:

Danaher's Dynapar Encoders' AI2512122B120 product exemplifies cutting-edge engineering. This encoder, which is made for industrial use, uses a Profibus connection and sophisticated diagnostic tools to keep the system aligned. Users may have accurate single-turn measurement control between 10 and 14 bits and multi-turn 12-bit resolution thanks to this encoder's strong processing power. The device's measurements stay constant within 7.2 arc-seconds and provide precision up to 36 arc-seconds. Using an encoder profile that produces digital output signals, the interface enables you to link Profibus-DP to your system. The gadget runs on a power input between 10 and 30 VDC and utilizes 220 mA in single-turn mode and 250 mA in multi-turn mode. It may automatically adjust its baud rate range from 9.6 KBaud to 12 MBaud to accommodate the communication speeds of all linked systems. The encoder operates with steady shaft movements at 10,000 RPM and reaches its maximum speed of 12,000 RPM with a low starting torque of less than 1.4 in-oz.

With weights of 350 g for single-turn designs and 400 g for multi-turn designs, its two variations are nonetheless lightweight and robust. The product functions between -40 degrees C and +85 degrees C, while the storage temperature can exceed +100 degrees C. To protect against dust and water contact, the encoder is available in two versions: IP64 and IP67. The product is robust in chemical-handling conditions since it is made of corrosion-resistant components and protective seals. By monitoring critical factors, such as temperature and input voltage, the AI2512122B120 can promote appropriate maintenance and maintain the encoder operating at peak efficiency. It can be purchased at Wake Industrial with a one-year warranty.
