1124989

Overview

The SICK model 1124989 is an absolute encoder from the AHS/AHM36 series. It features a hollow shaft design with a bore diameter of 10 mm and a total angular resolution of 12-bit single-turn data combined with 14-bit multi-turn capability, providing a total of 26 bits. The device utilizes an SSI interface for data transmission. It operates within a supply voltage range of 10 V DC to 30 V DC. The unit is housed in a robust metal enclosure rated IP67 for protection against dust and water ingress. The mechanical construction supports high rotational speeds up to 5000 rpm and includes a keyway for secure mounting.

Feature Summary

• Hollow shaft design accommodating a 10 mm bore for direct integration into rotating machinery without additional coupling mechanisms.
• High-resolution absolute position feedback combining 12-bit single-turn and 14-bit multi-turn data via SSI interface.
• Robust metal housing constructed to withstand industrial environments with an IP67 ingress protection rating.

Applications

• Position monitoring in automated material handling systems
• Integration into rotary indexing tables and turntables
• Feedback control for robotic joint axes

Procurement Notes

Verify the specific interface protocol and connector type required for your system integration before ordering. Confirm that the mechanical dimensions, particularly the 10 mm bore and mounting flange specifications, match your application's shaft requirements. Ensure the power supply provides a stable 10-30 V DC output compatible with the encoder's electrical load. Check for any necessary accessories such as mounting brackets or cables listed in the technical documentation.

Selection Notes

Select this model when a compact absolute encoder with a hollow shaft is required for space-constrained rotary applications. The 10 mm bore size is suitable for smaller shaft diameters commonly found in light to medium-duty automation equipment. The SSI interface is appropriate for systems requiring precise, noise-immune digital position data. Consider the IP67 rating if the installation environment involves exposure to washdowns or significant dust.

Part Context

This component belongs to the AHS/AHM36 family of absolute encoders manufactured by SICK. These devices are designed for motion control applications where reliable position feedback is critical. The series offers various bore sizes and interface options to suit different mechanical and electronic system architectures. Model 1124989 specifically denotes the configuration with the 10 mm hollow shaft and SSI communication protocol.

Replacement Considerations

When replacing existing units, ensure the new encoder matches the original bore diameter, mounting hole pattern, and shaft keyway specifications. Verify compatibility of the SSI interface with the host controller's input capabilities. Compare the electrical requirements, specifically the 10-30 V DC supply range, to avoid damage to the new sensor.
