Product Description:

The F141000/0300L is an incremental rotary encoder manufactured by Danaher for the Dynapar Encoders series. This hollow-bore device installs directly on a machine shaft and produces square-wave position pulses that a drive or PLC counts to determine precise speed or angular displacement. By providing direct electrical feedback without gears or mechanical linkages, the encoder supports closed-loop regulation on conveyors, winders, and servo axes where tight synchronization between commanded motion and actual shaft rotation is required.

The encoder operates from a 5 VDC ± 10% supply. The code wheel can tolerate angular acceleration of up to 100,000 rad/s² without pulse dropout, and its optical electronics resolve each revolution into 1000 PPR, providing 0.36 degrees of angular resolution to the controller. Signal integrity is maintained at frequencies as high as 250 kHz, supporting use in high-speed servo applications. The unit has a NEMA 1 / IP40 enclosure rating, providing protection against incidental contact with internal parts while keeping the housing compact for indoor installations. For mounting, the inside collar is 1.28 inches high and accepts a mating shaft with a minimum length of 0.50 inches; shaft runout must remain within 0.002 inches to prevent eccentric loading.

The hollow hub is machined with a 1/4-inch bore and a tolerance of +0.001/-0.000 inches. An allowable axial float of ±0.060 inches lets the encoder accommodate minor shaft movement without stressing its bearings. Electrical connection is provided through a 3-foot pigtail that carries the sensor’s open-collector incremental output, which sinks current supplied through an external pull-up circuit. During operation, the electronics draw a maximum of 150 mA, allowing the use of small-gauge conductors. A two-point tether with two No. 4 mounting points arranged on a 1.811-inch-diameter pattern prevents the housing from rotating with the shaft.
