Overview

The SICK AHM36A-SCQC000A30 (Order No. 1108598) is an absolute encoder from the AHS/AHM36 series, designed for precise rotational position measurement in industrial automation. It features a robust mechanical construction suitable for demanding environments. The system includes mounting systems and measuring wheel mechanics to facilitate integration with linear motion applications. 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 without requiring homing procedures upon power-up.
• Engineered for high reliability with documented safety-related parameters compliant with industrial standards.
• Compatible with dedicated mounting flanges and measuring wheel mechanics for linear axis integration.

Applications

• Linear positioning systems in automated manufacturing machinery
• Safety-critical axes requiring verified failure rate data
• Industrial equipment integrating rotary-to-linear motion conversion

Procurement Notes

Verify the specific order number against the required cable length and connector type, as variants exist within the product family. Confirm that the application environment aligns with the MTTFd calculation assumptions, specifically regarding ambient temperature and usage frequency. Ensure compatibility with the intended mounting hardware and measuring wheel components listed in the accessories section.

Selection Notes

Select this model when absolute position retention is required without battery backup or homing cycles. Consider the mechanical interface requirements, including the need for separate mounting flanges and measuring wheels. Evaluate the safety integrity level needs against the provided MTTFd value to ensure compliance with machinery directives. Verify that the physical dimensions and shaft specifications match the drive mechanism.
