Product Description:

Danaher Corporation is a globally recognized manufacturer known for producing precision instruments and industrial technologies. With a focus on motion control and automation, Danaher provides dependable solutions for demanding environments. The company designs components with durability, accuracy and performance in mind.

The HS351024844B7 is a Sealed Hollowshaft Incremental Encoder designed for reliable motion feedback. It supports a resolution range from 1 to 2500 PPR THAT ensures adaptability across control systems. This encoder includes dual channel quadrature outputs with an index pulse for accurate position tracking. Channel A leads B when rotated clockwise. This unit’s output waveform shows 90° electrical phase separation between signals. It provides a shaft loading capacity of 40 lbs. radial and 30 lbs. axial with a shaft speed limit of 3600 RPM. Users must consider temperature derating if operating above 1800 RPM. The shaft bore tolerance of this encoder is specified as nominal +0.0003" to +0.0005" (+0.008 mm to +0.013 mm). This encoder is well suited for applications requiring accurate motion control. It features a maximum weight of 16 oz. that maintains a compact and lightweight profile. Its quadrature output system including an index signal improves positional accuracy in automation systems.

This HS351024844B7 sealed hollowshaft incremental encoder has undergone testing to EN61326 industrial standards for noise immunity. It resists electrostatic discharge, conducted and magnetic interference, radio frequency interference and fast electrical transients. This ensures signal integrity in harsh environments. The encoder provides an enclosure rating of NEMA 4/IP67 that enables operation in dusty and wet industrial conditions. Its moment of inertia varies depending on bore size with 7.9 x 10⁻⁴ oz-in-sec² for ≤5/8” bore and 25.6 x 10⁻⁴ oz-in-sec² for >5/8” bore configurations.
