8 Position Wire to Board Terminal Block Horizontal with Board 0.200" (5.08mm) Through Hole ## Engineering Specification ## General Description The **1726202** is a Phoenix Contact **MKKDSN series PCB terminal block** designed for compact and reliable wire-to-board connection in printed circuit board assemblies. It is intended for applications that require secure field wiring, serviceable conductor termination, and stable electrical connection between external wiring and PCB circuitry. The component is suitable for industrial control systems, automation equipment, power interfaces, instrumentation, building controls, and general electronic hardware assemblies. ## Device Identification Manufacturer Part Number: **1726202** Manufacturer: **Phoenix Contact** Product Name: **MKKDSN 1,5/ 8-5,08** Product Family: **MKKDSN 1,5** Product Line: **COMBICON Terminals** Device Category: **Connector and Interconnect Component** Device Type: **PCB Terminal Block** Connection Type: **Wire-to-Board Terminal Block** Termination Method: **Screw Connection with Tension Sleeve** Mounting Type: **Through-Hole PCB Mount** ## Functional Description The device functions as a fixed printed circuit board terminal block that allows external conductors to be connected directly to PCB circuits. The screw-clamp connection secures the conductor mechanically while maintaining electrical continuity through the terminal body and solder pins. This makes the component suitable for wiring interfaces that require durability, accessibility, and field-service capability. ## Mechanical Description The terminal block uses a compact green housing with a two-row terminal arrangement and side-access conductor entry. Its layout supports dense wiring connection on a printed circuit board while maintaining practical access for conductor insertion and screw tightening. The through-hole solder pins provide mechanical stability and electrical connection to the host PCB. ## Electrical Description The component is intended for low-voltage power and signal connection applications within the manufacturer’s specified current and voltage ratings. It supports conductor connection for typical industrial and control wiring requirements when used with compatible wire sizes, correct strip length, and proper tightening torque. ## Material and Contact Description The terminal block uses an insulating housing with internal conductive contact elements designed to transfer current from the inserted conductor to the PCB solder connection. The screw connection with tension sleeve helps maintain stable contact pressure and reliable conductor retention during normal operating conditions. ## Mounting and Assembly Description The **1726202** is intended for through-hole PCB soldering, including wave-solder assembly processes. The PCB layout should follow the manufacturer’s recommended hole size, pad pattern, spacing, and soldering guidelines. The component should be positioned to allow safe conductor insertion, screwdriver access, and adequate clearance from nearby parts or enclosure walls. ## Application Suitability The device is suitable for industrial control boards, automation modules, relay boards, power supply interfaces, building automation equipment, instrumentation systems, sensor wiring interfaces, signal distribution boards, and other electronic products requiring secure PCB wire termination. ## Design Considerations The design should account for conductor size compatibility, current carrying requirement, voltage rating, creepage and clearance spacing, tightening torque, solder joint strength, wire routing, and user access during installation or maintenance. The terminal block should not be used beyond the manufacturer’s specified electrical, thermal, or mechanical limits. ## Hashtags #commonpartslibrary #terminalblock #pcbterminalblock #phoenixcontact #mkkdsn #mkkdsnterminalblock #combicon #wiretoboard #screwterminal #fixedterminalblock #throughholecomponent #wavesoldering #soldermount #connector #interconnect #fieldwiring #industrialelectronics #automationequipment #controlsystems #powerinterface #pcbdesign #hardwaredesign #electronicscomponents #electronicparts #engineeringparts #componentlibrary #electronicsengineering
