Product Description:

The HS35R1024D1A7PS Dynapar Encoder is a hollow-shaft rotary encoder that provides reliable motion feedback in various automation systems. This encoder is manufactured by Danaher and generates 1024 pulses per revolution (PPR) for precise position tracking and speed measurement. With its precise output, rugged construction, and high-speed capability, this encoder is well suited for various automation applications.

This encoder accepts a voltage input from 5 to 26 VDC so that it can be compatible with various systems and power supplies. The output voltage of this encoder remains at 5 VDC, which is a standard value for many digital interface devices. This encoder also includes a 10-pin output electrical connector with a mating connector to ease the installation and ensure good contact for current flow between the components. This dynapar encoder HS35R1024D1A7PS also has an indicator light to show the output status. This indicator provides feedback for real-time state monitoring and assists diagnostics while reducing maintenance time. This encoder is also resistant to vibrations of up to 20 G. This encoder uses the differential AB output to ensure maximum signal accuracy while eliminating electrical noise. The output configuration of this encoder is supported by a line driver (4469) to maintain stable performance.

This encoder has a bore size of 3/4 inch, and the hollow shaft allows direct mounting to the motor shaft without any other coupling parts. For mounting, a 4.5-inch C-face tether style is used for secure and stable mechanical support. This eliminates shaft rotation and improves the alignment accuracy. The HS35R1024D1A7PS dynapar encoder can operate at a maximum speed of 6,000 RPM. The housing material of this encoder is aluminum, a standard in all HS35R series, which is durable and corrosion-resistant.

Frequently Asked Questions about HS35R1024D1A7PS:

Q: How does the differential AB output in the HS35R1024D1A7PS help reduce signal interference?

A: It sends complementary signals on each channel, which helps cancel out electrical noise. This ensures clean signal transmission even in noisy industrial environments.

Q: Why is the line driver (4469) important in the HS35R1024D1A7PS encoder?

A: It maintains signal integrity over long cable lengths. This is crucial for systems that need precise timing and remote signal transmission.

Q: What benefit does the 10-pin connector provide in the HS35R1024D1A7PS encoder?

A: It simplifies installation and enhances contact reliability. This ensures consistent power and data transmission across the connected system.

Q: Why is 0.0353 Nm torque important in the HS35R02507241 encoder?

A: It minimizes mechanical load on the motor shaft. This allows smoother operation and extends component life in dynamic systems.

Q: Why is a 4.5-inch C-face tether style mount used in HS35R1024D1A7PS?

A: It prevents encoder rotation during operation. This keeps signal alignment accurate by maintaining the mechanical position.
