Device Identification
Manufacturer Part Number: 1726040
Manufacturer: Phoenix Contact
Product Series: MKKDSN
Device Category: Connector and Interconnect Component
Device Type: PCB Terminal Block
Connection Type: Wire-to-Board Terminal Block
Mounting Type: Through-Hole PCB Mount
Termination Method: Screw Connection
Functional Description
The device functions as a fixed printed circuit board terminal block that allows external conductors to be connected directly to a PCB. The screw-clamp mechanism secures the wire mechanically and electrically, providing a stable connection for signal or power circuits. The terminal block is intended for applications where field wiring must be removable, serviceable, and mechanically secure.
Mechanical Description
The component uses a compact green housing suitable for PCB-mounted assemblies. It is designed for side-entry conductor connection and horizontal board installation. The terminal block construction supports organized wire routing and convenient access for installation, maintenance, and service work.
Electrical Description
The terminal block is intended for low-voltage power and signal applications within the manufacturer’s specified current and voltage ratings. It provides reliable conductor contact when properly installed with compatible wire sizes and appropriate tightening torque.
Material and Contact Description
The connector housing is typically made from insulating material suitable for electrical safety and PCB assembly use. The internal conductive elements provide the electrical path between the inserted wire and the soldered PCB connection. Proper conductor preparation and screw tightening are required to maintain stable electrical performance.
Mounting and Assembly Description
The component is intended for through-hole solder mounting on a printed circuit board. Proper PCB hole sizing, pad layout, soldering process control, and mechanical clearance should be followed according to the manufacturer’s recommended design and assembly guidance. The terminal block should be mounted in a position that allows safe wire insertion and screw access.
Application Suitability
The 1726040 is suitable for industrial control boards, automation equipment, interface modules, power supply circuits, instrumentation, building control systems, relay boards, sensor wiring interfaces, and other electronic products requiring secure PCB wire termination.
Design Considerations
The design should account for wire gauge compatibility, current rating, voltage rating, tightening torque, creepage and clearance requirements, solder joint strength, and accessibility for field wiring. The terminal block should not be used beyond the manufacturer’s specified electrical, thermal, and mechanical limits.
