1079164

Overview

The SICK part number 1079164 corresponds to the M20S-081A2A122 safety light curtain. This device features 22 beams with a resolution of 25 mm and a scanning range of 810 mm. It supports protective operation, beam coding, and external device monitoring (EDM). The unit utilizes an M12, 8-pin male connector for interface connectivity.

Feature Summary

• Provides personnel protection through multi-beam detection with integrated beam coding.
• Supports external device monitoring (EDM) for enhanced system reliability.
• Designed for compact integration with a narrow 25 mm beam resolution.

Applications

• Machine guarding for press brakes
• Protection zones for injection molding machines
• Safety barriers for automated assembly lines

Procurement Notes

Verify that the specific application requires the M12 connector variant rather than the Hirschmann version. Confirm that the 810 mm height and 25 mm resolution meet the safety distance calculations. Ensure compatibility with the control system's support for EDM signals and beam coding protocols before finalizing the order.

Selection Notes

Select this model when a compact footprint is required alongside high-resolution detection. The M12 interface offers simplified wiring compared to older connector types. Consider the M20E variant if environmental conditions require an emitter unit instead of a receiver.

Part Context

This component belongs to the M20 series of safety light curtains from SICK. The series is characterized by its robust housing and versatile mounting options. The 'S' suffix indicates the receiver unit within the paired transmitter-receiver configuration.

Replacement Considerations
