HS35R02507251 by Danaher

The Danaher HS35R02507251 incremental optical encoder from the Dynapar Encoders series delivers high-precision motion feedback with up to 2500 PPR resolution. Engineered for industrial automation, the device features a sealed hollow shaft design and a robust, unbreakable code disk that withstands harsh conditions. Encased in an IP66 enclosure, it is optimized for washdown environments and can operate across a wide supply range from 4.5 VDC to 26 VDC. This encoder’s direct hollow shaft mount enables compact installation, reducing coupling backlash and simplifying alignment in constrained machine layouts. Its dual complementary output channels ensure reliable quadrature signals even under electrical noise.

Detailed technical specifications underscore the HS35R02507251’s engineering rigor. The unit provides a Resolution of 250 PPR per revolution and supports an Optional Z output via its Index Channel for homing functions. The Bolt Circle Diameter of 3" (76.2 mm) and a Bore Size of 1/2" facilitate standard mechanical interfacing, while its Gross Weight of 1.75 lbs (0.79 kg) maintains a favorable power-to-weight ratio. Noise Immunity conforms to EN61326-1 compliance, and the encoder’s Output Driver is a high-speed Line Driver with either Open-collector or Push-Pull Output Type. Operating at a constant Output Voltage of 5 VDC, it connects via a 7-pin connector Termination to simplify wiring harness integration.

Operational features of the HS35R02507251 emphasize reliability and performance stability. The sealed Shaft Type hollow design resists ingress of moisture and contaminants, ensuring continuous operation in washdown or high-humidity environments. Its unbreakable code disk guarantees consistent signal generation across 250 pulses per rotation, while complementary AB channels minimize missing count errors. The device tolerates supply variations from 4.5 VDC to 26 VDC, providing resilience against voltage transients in industrial power networks. As a result, the encoder sustains accurate speed and position feedback in dynamic applications with minimal maintenance.

System integration is streamlined for motion control architectures in robotics, conveyor tracking, and packaging machinery. The HS35R02507251’s quadrature outputs interface directly with PLCs, motion controllers, and servo drives without intermediary signal conditioning. Its compact profile and standardized mounting reduce design iterations and installation time in automated assembly lines. Ideal for harsh industrial environments, this encoder delivers precision feedback for machine tools, material handling systems, and rotating equipment across a broad range of automation applications.
