Lot of 10: Siemens 3TX7144-4E5 14-Pin Relay Sockets
Ensure your industrial control panels are secure and organized with this Lot of 10 Siemens 3TX7144-4E5 Relay Sockets. These high-quality sockets are designed for 14-pin miniature relays (typically 4PDT), providing a reliable interface between your control wiring and the relay logic.
Featuring Elevator Terminals and a Touch-Safe design, these sockets prioritize both ease of installation and operator safety, making them a staple for professional electrical engineering and maintenance.
Key Features
Touch-Safe Design: Engineered to prevent accidental finger contact with live terminals, enhancing safety during maintenance and inspection.
Elevator Terminals: Utilizing a “cage” or elevator-style clamping mechanism, these terminals provide superior wire retention and prevent “bird-nesting” of stranded wires.
14-Pin Configuration: Standardized footprint compatible with most 14-pin miniature plug-in relays (4-pole double-throw).
DIN Rail Mountable: Designed for quick snapping onto standard 35mm DIN rails, but also supports screw mounting for traditional panels.
Industrial Durability: Built to Siemens’ rigorous standards for high-vibration and high-temperature industrial environments.

Installation Benefits
The Elevator Terminals are particularly beneficial for high-density wiring. Unlike standard pressure plates that can twist or damage fine wire strands, the elevator clamp rises and falls vertically to apply even pressure across the entire wire surface, ensuring a low-resistance connection that won’t vibrate loose over time.
