The TE Connectivity / Entrelec M6/12.FF 1SNA400753R1000 is a robust 6 mm² stud connection feed-through DIN rail terminal block designed for reliable electrical connections in industrial control panels, machinery and demanding electrical systems. Part of the established Entrelec SNA stud terminal block range, it is particularly suited to applications where ring lug connections and resistance to vibration are important.
The M6/12.FF features two 8-32 UNC-2A studs and is supplied with nuts for secure ring lug termination. Stud connections provide strong mechanical retention, making this terminal block well suited to high-vibration environments and industrial equipment where dependable conductor connections are essential. A removable partition also enables jumpering when required.
With a rated cross-section of 6 mm², an IEC rated current of 41 A and rated voltage of 800 V, the M6/12.FF provides dependable electrical performance in a compact DIN rail format. Its 12.5 mm spacing and compatibility with G32 and TH35 DIN rails allow straightforward integration into industrial control and distribution assemblies.
Stud terminal blocks provide a mechanically secure electrical connection by fastening ring lugs directly onto threaded studs. This connection method is particularly valuable in applications exposed to vibration, where strong conductor retention and dependable electrical contact are required over long periods of operation.
The M6/12.FF combines this proven stud connection technology with an 800 V, 41 A IEC rating and compact DIN rail construction. Its removable partition allows adjacent terminals to be jumpered when required, while compatibility with several common DIN rail profiles makes it versatile for industrial panel building, machinery and electrical distribution systems.
