Product Description:

The E14100000704 belongs to the Dynapar Encoders series produced by Danaher for motion-feedback tasks in industrial automation. It is an incremental rotary encoder that mounts on a 1/4-inch shaft and delivers position and speed data to drives and controllers, allowing closed-loop regulation of motors, conveyors, or web-handling equipment. A separate index channel provides a once-per-revolution reference pulse for homing routines, while the quadrature outputs indicate movement and direction.

The encoder operates from a tightly regulated 5 VDC ±5% supply and has a maximum current draw of 80 mA, so it can be powered directly from typical PLC I/O rails. Its differential line driver is a 7272 differential line driver, providing balanced outputs that resist electrical noise over long cable runs. Resolution is fixed at 1000 PPR, providing the controller with enough pulses to track shaft movement accurately. The sensing electronics support a minimum frequency response of 100 kHz, allowing accurate edge detection even at high rotational rates. The code wheel can spin continuously at up to 5000 rpm without bearing distress, and starting torque does not exceed 0.43 oz-in, keeping the mechanical load on the connected drive minimal.

The permanently sealed bearing set handles a maximum axial thrust of 3 lb and a maximum radial load of 5 lb, so couplings and belts can be applied without overloading the shaft. Installation flexibility is aided by a factory-attached 15 ft shielded cable that carries power and quadrature signals to the control cabinet. Low moving mass is achieved through a moment of inertia of 3.8 × 10⁻⁵ oz-in-s², allowing rapid acceleration profiles, while the overall weight remains under 3.0 oz to reduce strain on delicate assemblies.
