Product Description:
The E151000220124 is a rotary incremental encoder manufactured by Danaher as part of the Dynapar Encoders series. It converts shaft rotation into discrete electrical pulses so motion controllers can monitor speed, direction, and travel in automated machinery. The encoder can be installed directly on a 1/4-inch drive shaft or connected through a flexible coupling. Its A/B quadrature signals allow a controller to detect changes in direction with minimal latency, while system software handles position referencing because the encoder does not provide an index channel.
The encoder delivers a resolution of 1000 PPR, producing one thousand pulses per revolution for position tracking. Its frequency response is at least 100 kHz, allowing the connected controller to detect pulses reliably at elevated rotational speeds. When powered by 5 VDC, the single-ended outputs provide A/B quadrature waveforms that interface directly with compatible TTL or CMOS counters. The shaft supports rotational speeds up to 5000 rpm without exceeding its bearing or signal limits. Its solid shaft has a diameter of 1/4 in for use with compact servomotors and related rotating equipment. Starting torque is limited to 0.1 oz-in, while running torque is limited to 0.08 oz-in, reducing the mechanical load placed on delicate drive trains.
The encoder weighs 3.0 oz, making it suitable for small rotating assemblies where added mass must remain low. Its rotor has a moment of inertia of 4.5 × 10⁻⁶ oz-in-s², helping preserve responsive acceleration and deceleration profiles. Axial force on the shaft must not exceed 3 lb, while the permitted radial load is 5 lb; maintaining these limits helps prevent premature wear of the shielded bearings. An attached cable measuring 3 ft provides sufficient length for routing within a compact control cabinet without requiring an additional connector or extension cable.
