Product Description:

The HA6251500061018 from the Dynapar Encoders series provides precise rotational data for various industrial applications as an incremental encoder.

This model includes 1 to 2540 pulses per revolution options to fulfill diverse motion control precision needs. The encoder has dual channel AB quadrature outputs and optional Z index signals for easy system compatibility and combination. The device enables Channel A to reach its target before B during clockwise shaft motion observed from the machine end to deliver precise readings about mechanical movement. The quadrature phasing remains within 90degrees of electrical phase while maintaining 180degrees ± 18degrees of symmetry for both signals. The encoder operates according to the specified 180degrees electrical index angle (with B at its low state). The square wave output exhibits fast transitions below one microsecond into a 1000 pF load, so users can rely on it for high-speed tasks. The encoder takes an input of up to 26 VDC at 80 mA power except for output loads. It offers three types of outputs, including Open Collector, Push-Pull, and Differential Line Driver for different connection needs.

In high-temperature environments, the index channel continues working above 75 kHz while the complete system operates at a basic 100 kHz. The device accepts shaft sizes of 1/4 and 3/8 while its shaft load rating is 35 lbs radial and 40 lbs axial at a distance of 0.25 from the encoder face. It works with shaft speeds up to 5,000 RPM. This encoder type delivers 2.5 oz-in initial torque at 25 degrees C and shows outstanding durability with an operating range from 0 to +85 degrees C and storage range from -40 to +90 degrees C, and meets NEMA4/IP66 standards. It can be purchased at Wake Industrial with a one-year warranty.
