Product Description:

Danaher's H2101200225AH encoder is part of the H20 HUB SHAFT Series and is made to give motion control systems accurate rotary input. It has a hub shaft design that makes installation easier and fits with normal mechanical connections. This encoder was made by Danaher to meet the operating standards needed in automation control applications.

The input voltage range for the H2101200225AH encoder is 5 to 26 VDC, and it has a single-ended output through an open collector electrical link. It sends incremental input through a single one-way channel and has a resolution of 120 pulses per revolution. The item is made with a 5/8" hub shaft that has a shaft seal to protect the internal parts. It has a 1.5-inch bolt circle that makes it easy to line up with normal mounting arrangements. The encoder uses optical sensing to make sure the information is accurate and has bearings to support it mechanically. It can work in temperatures from -40 °C to 85 °C, so it can be used in many temperature-sensitive situations. The end is a 10-foot sealed wire that comes out of the side and doesn't come with a connector that fits. The hub-mounted type of gear makes it easier to connect to hardware that works with it. The enclosure is NEMA 4 compliant and has an IP66 grade, which means it keeps out water and other elements.

The < doesn't have any built-in state indicators, so its feedback output is limited to signals only. The encoder is designed to meet standards for data integrity and accurate mounting. The product can be used in situations where accurate incremental feedback is needed without the need for extra channels of contact. The H2101200225AH is designed for systems that need reliable input with little signal noise.

Frequently Asked Questions about H2101200225AH:

Q: How does H2101200225AH achieve IP66 protection rating?

A: The sealed housing and shaft seal block dust and water ingress. This protection ensures long-term encoder functionality in exposed environments.

Q: Why is H2101200225AH designed without an index marker?

A: The encoder is built for continuous rotary motion feedback. It does not require position referencing for standard incremental applications.

Q: Does H2101200225AH include a commutation function?

A: No, the encoder lacks commutation tracks. It is not intended for servo motor control with embedded phase feedback.

Q: How do bearings support H2101200225AH mechanical reliability?

A: The internal bearings provide rotational stability and load handling. This enhances the encoder's durability during continuous shaft operation.

Q: Do H2101200225AH signal channels support bidirectional motion?

A: No, the encoder provides single-channel unidirectional output. It is suited for systems requiring motion feedback in one direction only.
