Product Description:

The E2325000942 is an incremental optical encoder belonging to Dynapar encoders series engineered by Danaher. It offers dependable feedback in industrial automation and light machinery. The E23250 Dynapar encoder has integrated short circuit and reverse polarity protection. Its noise immunity complies with EN61326-1 for reliable performance in electrical environments.

The E2325000942 Dynapar encoder features a 2540 PPR resolution and uses optical sensing for accurate position signal generation. It supports input voltages ranging from 5 VDC to 26 VDC and the output signal voltage is equal to the input voltage range. The E23250 Dynapar encoder has a 7272-line driver which provides balanced and noise-immune signal output. It has a maximum frequency response of 250 kHz and duty cycle is specified between 43% to 57% for stable output. The E23250 Dynapar encoder includes a pre-attached 6-foot pigtail cable for termination and has a radial side-exit for cable routing. Its housing diameter is 2.3 inches designed from lightweight aluminum. The E23250 Dynapar encoder is shafted with a stainless steel 6.35 mm while the axial and radial shaft loading is 22.2 mm. It has glass disk to enable precise optical encoding with low signal distortion. The E23250 Dynapar encoder’s starting torque is 0.07 N-cm and operates at a maximum mechanical speed of 5000 RPM.

The E2325000942 Dynapar encoder is rated for 50G shock resistance over 11-millisecond duration and has a vibration tolerance of 20G over 5 to 2000 Hz frequency range. Its enclosure is rated IP54 and has operational temperature range of 0°C to 70°C and humidity tolerance is up to 98%. The E23250 Dynapar encoder delivers incremental signals A, A’, B, B’, Z, and Z’. The signal format is C with A leading B in clockwise rotation and the Index pulse is 18° ± 9° gated to channel B.
