6079937

Overview

The SICK model 6079937 is an EES/EEM37 series HIPERFACE DSL® motor feedback encoder. It utilizes a capacitive measurement principle with integral scanning to provide high-precision position and speed data for servo applications. The device features a compact structure suitable for small and micro motors, operating within a supply voltage range of 7 V to 12 V. Key electrical parameters include a resolution of 15 bits per revolution, 32,768 measurement steps per revolution, and a system accuracy of ±280 arcseconds at nominal position (25 °C). It supports up to 8,192 bytes of user memory and communicates via the HIPERFACE DSL® interface.

Feature Summary

Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm exact pinout and cable configuration. Ensure the application environment remains within the specified temperature range of -40 °C to +115 °C. Confirm that the power supply strictly adheres to the 7 V to 12 V operating window to prevent damage. Check for any recent product lifecycle notifications regarding availability or replacement parts.

Selection Notes

Select this component when a resolver replacement is required in a space-constrained servo motor. The capacitive sensing technology offers superior tolerance to mechanical misalignment compared to optical alternatives. Verify that the host controller supports the HIPERFACE DSL® protocol for initialization and data retrieval. Consider the 15-bit resolution and 8 KB memory capacity for complex motion control requirements.

Part Context

This encoder belongs to the EES/EEM37 family from SICK, specialized for direct integration into electric drives. The series is engineered to replace traditional analog feedback devices like resolvers in demanding industrial automation scenarios. It provides a digital solution that maintains high precision while minimizing the physical footprint of the motor assembly.

Replacement Considerations

Consult official SICK documentation for verified substitute part numbers. Do not assume cross-compatibility with other encoder families without validating interface protocols and mounting dimensions.
