Product Description:

The AI25001321127 Absolute encoder is a high-precision motion feedback encoder manufactured by Danaher. The encoder is compatible with many integration standards and has a standard form factor, making it perfect for industrial automation. The encoder meets the system requirements for consistent and precise placement.

The AI25001321127 absolute encoder guarantees accurate data every revolution with its single-turn resolution of 13 bits. The encoder's input power range of 10-30 VDC makes it suitable for systems with changing voltage levels. The usual mounting configuration of the encoder is capable of supporting shafts that have a diameter of three-eighths of an inch. The shaft seal is not included with the encoder. To accommodate common connection configurations, a 17-pin radial CW connector from M23 Conin was used. The operational temperature range is from -40°C to 100°C. Spilled water and grime are effectively prevented by its IP64 rating. Optical sensing, which uses light transmission technology, enables the AI encoder to deliver accurate feedback. Electrical and safety standards have been met by the encoder, as it has been validated by the CE, cUL, and UL. The encoder is not explosion-proof when constructing the system.

The AI25001321127 absolute encoder does not come with built-in features for explosion-proof status or shaft sealing. The encoder is designed to function reliably within the temperature and protection limits indicated. When it comes to reliable voltage compatibility and single-turn accuracy, the built-in design and protocol are ideal. The shaft-based design of the encoder simplifies installation while also ensuring signal integrity with its parallel output. In automation, the AI Absolute Encoder is the ideal choice when reliable motion feedback and the capacity to adjust to integration are indispensable.

Frequently Asked Questions about AI25001321127:

Q: How does AI25001321127 maintain signal stability?

A: AI25001321127 uses a voltage range of 10–30 VDC that helps maintain stable power input across different automation platforms.

Q: Why does AI25001321127 not include a shaft seal?

A: The encoder omits a shaft seal for systems that require a direct shaft interface without added sealing that may impact mounting simplicity.

Q: Does AI25001321127 meet safety compliance standards?

A: Yes, AI25001321127 holds CE, UL, and cUL approvals that confirm compliance with recognized electrical safety and equipment certification standards.

Q: Why is AI25001321127 rated IP64 for protection?

A: The IP64 rating offers limited dust protection and splash resistance that make AI25001321127 suitable for partially enclosed control systems.

Q: Do temperature extremes affect the AI25001321127 encoder?

A: No, AI25001321127 is designed to operate from -40 to 100 °C, which ensures thermal stability in varying temperature environments.
