SICK SX0A-A0000B 2023797

SICK Connection Box for M4000 Series Description The SICK SX0A-A0000B is a dedicated connection box designed for the M4000 series of safety light curtains. This module simplifies the wiring process, providing a robust and organized interface for power, safety signals (OSSDs), various inputs, and RS422 communication. It is an ideal solution for maintaining or extending existing M4000 safety systems, especially in cascading configurations. Specifications Manufacturer: SICK Type: Connection Box Model: SX0A-A0000B Part Number: 2023797 Supply Voltage: 24V DC Compatibility: SICK M4000 Advanced, M4000 Advanced A/P, M4000 Advanced Curtain Interfaces: OSSD safety outputs, digital inputs, RS422 Label Info Model: SX0A-A0000B Part No: 2 023 797 Serial No: 2038 1045 Application This connection box is used in industrial automation environments to connect SICK M4000 safety light curtains to a machine’s control system. It provides a central point for all necessary electrical connections, ensuring reliable operation and simplifying installation and maintenance. Country of Origin Made in Hungary. CO2 Impact Choosing this reused SICK connection box prevents the emission of approximately 12 kg of CO2 compared to manufacturing a new one. This saving is equivalent to the CO2 absorbed by a mature tree over a year. Availability This is an obsolete item, available as New Old Stock (NOS). Availability is limited.

FAQ Can this connection box be used with the newer SICK deTec4 light curtains?No, the SX0A-A0000B is specifically designed for the M4000 series. The pinout, connector, and internal logic are not compatible with the deTec4 series, which uses a different connection system, often with M12 connectors. What is the purpose of the RS422 connections (pins 25-28) on this module?The RS422 interface on the M4000 Advanced models, accessed via this connection box, is used for configuration, diagnostics, and data transfer. It allows connection to a PC with SICK’s CDS (Configuration and Diagnostic Software) for setup and monitoring. What does OSSD mean and why are there two (OSSD 1 and OSSD 2)?OSSD stands for Output Signal Switching Device. These are the primary safety outputs of the light curtain. Safety standards require two redundant, self-monitoring outputs. Both OSSDs must be in a HIGH state for the machine to operate. If either goes LOW (e.g., when the light beam is interrupted), the machine’s safety circuit is triggered to stop the hazardous motion. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
