Product Description:
Danaher manufactures the E2312300X4X15 as part of the Dynapar Encoders series. The unit is an incremental rotary encoder that generates square-wave feedback signals for reporting shaft position and velocity in industrial automation systems. A glass code disc sets the resolution, while the stainless steel shaft turns in precision bearings inside an aluminum housing. This configuration allows machine controllers to monitor motors, gearboxes, or line shafts without mechanical gearing or complex sensor arrays. The encoder can support motion feedback in equipment that requires consistent position counts and dependable speed measurements.
The housing is rated NEMA 12/IP54, protecting the internal components against airborne dust and splashed fluids when a gasketed cover is fitted. The stainless steel shaft has a diameter of 1/4 in., allowing direct connection to common flexible hubs. The maximum axial and radial bearing load is 5 lb, which helps prevent excessive stress on the shaft assembly. Continuous rotation is permitted at speeds up to 5,000 rpm, provided the operating load remains within the allowable limits. The encoder weighs no more than 13 oz., minimizing the overhung load on small motors and compact drive assemblies. Its aluminum housing provides a rigid mounting structure without adding substantial mass to the rotating equipment.
The output channels track code-wheel motion at frequencies of at least 100 kHz, supporting high-speed control loops and rapid position counting. Rising and falling edges propagate through the driver electronics in less than 1 µs at 1,000 pF, helping maintain clean counts when long cable runs add capacitance. Channel phasing remains within 90° ±18° electrical, while duty cycle symmetry remains within 180° ±9° electrical, simplifying direction decoding by the connected controller. Rotor inertia is 3.7 × 10⁻⁴ oz-in-sec², allowing the shaft to accelerate with minimal lag during speed changes. At 25 °C, the bearing system requires only 0.2 oz-in of starting torque, limiting the mechanical load drawn from low-power servo motors. These signal and motion characteristics allow the encoder to respond quickly without placing excessive resistance on the monitored shaft.
