The TE Connectivity HD4/9.F4 1SNA295391R2000 is a robust M4 stud feed-through terminal block designed for secure electrical connections in industrial and railway control systems. Part of the established Entrelec SNA HD terminal block range, it combines a durable stud connection with compact DIN rail mounting for dependable conductor termination in demanding electrical installations.
The HD4/9.F4 uses a M4 × 11.5 mm stud connection supplied with a self-locking nut, spring washer and washer. This bolted connection method provides a secure mechanical and electrical interface for conductors fitted with suitable cable lugs, making the terminal particularly useful where vibration resistance, reliable contact pressure and long-term connection integrity are important.
With a rated cross-section of 4 mm², rated current of 32 A and rated voltage of 500 V AC/DC, the 1SNA295391R2000 provides reliable feed-through connectivity for industrial and transportation electrical systems. Its 9.5 mm spacing, beige polyamide housing and compatibility with TH35 DIN rails make it suitable for compact, organised terminal assemblies.
Stud terminal blocks use a threaded connection to clamp cable lugs securely against the conductive terminal assembly. This provides strong mechanical retention and reliable electrical contact, making stud technology particularly suitable for industrial and transportation applications where connections may be exposed to vibration and demanding operating conditions.
The HD4/9.F4 combines this robust connection method with a compact DIN rail format. Its M4 stud, self-locking hardware and 1.2 N·m tightening torque provide a repeatable termination method, while the SNA HD construction makes it suitable for professional panel builders, railway equipment manufacturers, machine builders and industrial automation engineers.
