Product Description:

The H222048104143PS is an incremental optical encoder produced by Danaher as part of the Dynapar Encoders series. Installed on a motor or machine shaft, it converts mechanical rotation into square-wave pulse trains that a drive or PLC can count for position or speed feedback. By supplying two phased output channels, the device supports direction sensing and helps maintain closed-loop control in conveyors, pick-and-place modules, and other automated equipment that requires real-time angular data.

A resolution of 2048 PPR means the encoder delivers 2048 discrete pulses per revolution, providing measurement steps of 0.175°. The electronics accept a supply of 5 to 26 VDC, allowing the unit to receive power directly from common control rails. A minimum frequency response of 100 kHz allows accurate edge detection even at elevated shaft speeds. Output channels are driven by a 5 V differential line driver, which provides balanced signals that reject electromagnetic interference across long cable runs. The housing meets NEMA 12/IP54 sealing requirements, blocking dust and resisting splashed liquids in standard control cabinets. A front-panel LED provides visual confirmation of power and signal integrity, while a 7-pin side connector carries the supply and quadrature outputs.

The encoder has a maximum rotational speed of 5000 rpm, allowing the glass code disc to remain stable during high-speed service. Starting friction is limited to 1.0 oz-in, adding negligible load to small servo or stepper motors. The solid shaft has a diameter of 3/8 in and is centered by a 1.25-inch pilot for concentric alignment. The bearings tolerate 40 lb of combined radial or axial force, helping preserve accuracy under belt tension or thrust loads. Continuous operation is permitted from 0 to +70 °C, which accommodates typical electrical-panel temperatures. Four #6-32 screws arranged on a 2.00-inch bolt circle secure the encoder face to its mounting surface.
