1121849

Overview

The SICK part number 1121849 corresponds to the AHM36A-SCQC000A30, an absolute encoder from the AHS/AHM36 series. This device is designed for precise position feedback in industrial automation applications. It features a robust rectangular housing with dimensions of 12 mm x 40 mm x 26 mm. The unit utilizes an M8, 3-pin connector for connection and operates with a PNP switching output. Key technical parameters include a sensing range (Sn) of 4 mm and a safe sensing range (Sa) of 3.24 mm. The encoder supports a switching frequency of 2,000 Hz and is rated IP68 according to EN 60529. It employs DC 3-wire electrical wiring and includes special characteristics such as a different oscillator frequency.

Procurement Notes

Verify the specific ordering suffix and variant configuration against the official SICK product catalog to ensure compatibility with existing system interfaces. Confirm that the M8 connector pinout and PNP output logic align with the target controller requirements. Cross-reference the part number 1121849 with the associated AHM36A-SCQC000A30 designation to validate the correct mechanical and electrical specifications for the intended application environment.

Selection Notes

Select this component when a compact, flush-mountable absolute encoder with IP68 protection is required. Ensure the application demands a 4 mm sensing range and 2,000 Hz switching frequency. Verify that the M8 3-pin connector interface is compatible with the available cabling infrastructure. Consider the rectangular housing dimensions for spatial constraints within the assembly.

Part Context

This part belongs to the SICK AHM36A series of absolute encoders, which are engineered for use in measuring wheel mechanics. The series is characterized by modularity, allowing for flexible combinations of encoders and interfaces. These components are typically paired with measuring wheels like the BEF-MWS120-ARM to provide accurate linear position data in automated systems.
