1116955

Overview

The SICK part number 1116955 corresponds to the M20S-081A2A122 safety light curtain. This device is a two-beam safety sensor designed for protective operation with beam coding and external device monitoring (EDM). It features a vertical scanning range of 16 mm and a horizontal resolution of 25 mm. The unit utilizes an M12, 8-pin male connector for interface connectivity.

Feature Summary

• Supports protective operation mode with integrated beam coding technology
• Includes external device monitoring (EDM) functionality for safety circuit verification
• Utilizes a compact two-beam design for precise object detection

Applications

• Protective guarding for industrial machinery access points
• Safety zones requiring high-resolution detection in confined spaces
• Integration into automated manufacturing systems with EDM requirements

Procurement Notes

Verify the specific suffix against the official SICK catalog to confirm connector type and cable length. Ensure the ordering code matches the required protection level and mounting configuration for your application. Cross-reference the订货代号 (Ordering Code) 1018196 with current manufacturer documentation to validate availability and technical specifications before purchase.

Selection Notes

Select this model when a narrow 16 mm scanning range is sufficient for the safety zone. The 25 mm resolution is suitable for detecting fingers or small objects. Confirm that the M12 connector interface aligns with existing control cabinet wiring standards. Verify compatibility with the host PLC's safety input requirements.

Part Context

This component belongs to the M20 series of safety light curtains from SICK. The series offers various resolutions and scanning ranges tailored for different machine safety applications. The M20S variant specifically denotes the sender unit within a paired transmitter-receiver system.

Replacement Considerations

Direct substitutes include the M20E-081A2A122 receiver unit for complete system pairing. Other M20 series models with identical 16 mm range and 25 mm resolution may serve as functional equivalents if connector types match.
