1115875

Overview

The SICK part number 1115875 corresponds to the AHM36A-SCQC000A30, an absolute encoder from the AHS/AHM36 series. This device is a standard product and does not constitute a safety component as defined in the Machinery Directive. It features a robust mechanical design suitable for industrial automation environments. The unit includes integrated measuring wheels and mechanics for linear position detection. Technical documentation specifies a Mean Time to Dangerous Failure (MTTFd) of 240 years based on EN ISO 13849-1 standards, calculated under nominal load conditions at an average ambient temperature of 40°C with a frequency of use of 8760 hours per year.

Feature Summary

• Provides absolute position data via integrated measuring wheel mechanics
• Features modular design allowing flexible encoder mounting in 30-degree increments
• Includes mechanically protected spring travel to compensate for surface unevenness

Applications

• Linear measuring tasks in material handling systems
• Position monitoring in automated manufacturing processes
• Integration into machinery requiring reliable linear displacement feedback

Procurement Notes

Verify the specific variant suffix against official SICK documentation to ensure correct interface and mechanical configuration. Confirm that the application environment aligns with the calculated MTTFd parameters, specifically regarding ambient temperature and usage frequency. Ensure compatibility with the host controller's communication protocol before procurement.

Selection Notes

Select this model when absolute linear position feedback is required without external reference runs. Consider the compact axle spacing of 63.5mm for space-constrained installations. Evaluate the need for specific measuring wheel surfaces based on the contact material characteristics. Verify that the system requirements do not mandate a certified safety component, as this unit is classified as a standard product.

Part Context

This component belongs to the SICK AHS/AHM36 series of absolute encoders designed for industrial measurement applications. The series emphasizes modularity, allowing users to combine different measuring wheels with various encoder interfaces. It is engineered for durability in demanding factory environments, offering adjustable contact pressure and protection against spring overload.

Replacement Considerations

Consult official SICK cross-reference guides for direct substitutes. Ensure any replacement maintains the same absolute encoding technology and mechanical mounting dimensions. Verify interface compatibility with existing control systems.
