Baumer Electric AG 451A010 Incremental Encoder

Baumer Electric AG 451A010 Incremental Encoder is a compact, optical incremental encoder with a ø30 mm housing and a 5 mm solid shaft, ideal for tight spaces where reliable quadrature feedback is required. It supports A/B channel outputs with a reference (zero pulse) signal and a 90° phase relationship, with an inverted N option, and can operate from 5 VDC or 10–30 VDC, consuming about 60 mA at 5 V (no load) or 30 mA at 24 V (no load). The device offers a pulses-per-revolution range of 10 to 2048, enabling a spectrum from low to high resolution, and an output frequency capability up to 100 kHz. Sensing is optical, and the encoder provides EMI protection compliant with EN 61000-6-2 and emissions limits per EN 61000-6-3, with UL approval E217823. Mechanical design includes a synchro flange for secure mounting and admits shaft loads up to 10 N axial and 10 N radial; protection levels listed include IP42 and IP64 depending on configuration. Typical applications span motor feedback in compact automation, CNC tooling, robotics, conveyors, and packaging equipment where compact form factor, deterministic signaling, and robust environmental tolerance are essential.
