Product Description:
The EC2350001938 is an incremental rotary encoder produced by Danaher for the Dynapar Encoders series. In motion-control systems, this component attaches to a rotating shaft and converts mechanical angle into a timed pulse train that a drive or PLC interprets for velocity regulation and position verification. Its construction and electrical interface are intended for general factory automation applications that require precise, noise-resistant feedback.
The encoder uses a sealed bearing arrangement that blocks dust and moisture, helping extend service intervals in conveyor, packaging, and assembly machinery. Signal granularity is set at 5000 PPR, meaning each revolution is divided into 5,000 pulse intervals to support fine positioning. A stainless-steel shaft with a 1/4-inch diameter fits directly into standard couplings without additional adapters. The encoder has a differential output, so complementary A and B signals help cancel common-mode noise over twisted-pair cabling. Driver electronics meet the 7272 line-driver standard, enabling both sourcing and sinking of up to 20 mA while maintaining voltage margins under dynamic loads. These output characteristics support stable signal transmission through electrically noisy factory environments and along cable routes near motors or power conductors.
Logic amplitude is held at 5 VDC, matching TTL-compatible inputs on many servo drives and industrial controllers. Channel timing follows Format C, which supplies two quadrature outputs with equal mark-space ratios for accurate edge detection. The encoder has no index channel and therefore omits the once-per-revolution Z pulse, so the control system must obtain a homing reference from an external device or established machine position. The clockwise phase orientation causes channel A to lead channel B when the shaft rotates clockwise, allowing the connected controller to determine direction from the phase relationship. Field wiring is completed on screw terminals, allowing connections to be made without soldering or proprietary connectors while keeping cable-shield routing straightforward.
