6ES7492-1CL00-0AA0 48-Pole Crimp Front Connector

Verified connector identification and procurement guidance for SIMATIC S7-400 signal and function modules.

Product Overview

Siemens 6ES7492-1CL00-0AA0 is a 48-pole SIMATIC S7-400 front connector with crimp contacts. Siemens documents it for signal modules and function modules, providing a practical interface between field wiring and the installed module.

The connector supports user-friendly sensor and actuator connections, preserves the wiring when a compatible module is replaced, and uses coding to reduce connector errors during maintenance.

Commercial Status

Verified Technical Data

System Fit and Applications

• Connection of sensors and actuators to compatible SIMATIC S7-400 signal modules.
• Front wiring for S7-400 function modules requiring a 48-pole connector.
• Maintenance replacements where the installed field wiring should remain with the connector.
• FM 450-1 counter-module applications documented with a 48-pole crimp front connector.

Compatibility and Procurement Checks

• Confirm the full module order number and that a 48-pole front connector is required.
• Verify that the installation uses crimp contacts rather than screw contacts or spring-loaded terminals.
• Check terminal coding, existing wiring documentation and conductor preparation.
• Confirm whether crimp contacts 6XX3070 and crimping tool 6XX3071 are available for the installation.
• Compare the existing connector label and mechanical fit before treating another 6ES7492 variant as interchangeable.
• Request current condition, quantity, packaging, delivery and warranty details before ordering.
