Siemens 3RG4041-6KD00 129258 SIMATIC PXI340 Proximity Switch Sensor Inductive
The Siemens 3RG4041-6KD00 (Siemens order number 129258) is a compact and reliable safety switching device from the SIRIUS 3RG4 safety relay family, designed to monitor emergency stop (E-STOP) circuits, protective devices, and safety contacts in industrial machinery and automated systems. This single-function safety module provides forced-guided relay contacts compliant with international safety standards (EN ISO 13849, IEC 62061), making it ideal for applications requiring Category 3 or 4 safety architectures per EN 954-1.
Featuring a manual reset function, the 3RG4041-6KD00 ensures that after an emergency stop activation or safety circuit interruption, the system cannot restart automatically—requiring deliberate human intervention to restore operation. This critical safety behavior prevents unexpected machine restarts, protecting personnel during maintenance, jam clearing, or fault conditions.
