2 Position Wire to Board Terminal Block Horizontal with Board 0.150" (3.81mm) Through Hole ## Engineering Specification ## General Description The **1727010** is a Phoenix Contact **MKDS series PCB terminal block** designed for secure wire-to-board electrical connection in printed circuit board assemblies. It provides a compact screw-clamp termination interface for connecting external conductors to PCB circuitry. The component is suitable for industrial electronics, automation equipment, control modules, power interfaces, instrumentation, and general electronic assemblies requiring reliable field wiring termination. ## Device Identification Manufacturer Part Number: **1727010** Manufacturer: **Phoenix Contact** Product Name: **MKDS 1/ 2-3,81** Product Series: **MKDS** 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 PCB terminal block that allows external wires to connect directly to the printed circuit board. The screw-clamp mechanism provides both mechanical conductor retention and electrical continuity between the field wiring and PCB circuit. This makes the component suitable for applications where wiring must be secure, serviceable, and accessible during installation or maintenance. ## Mechanical Description The terminal block uses a compact housing with side-entry conductor access and through-hole solder pins for stable PCB attachment. Its construction supports organized wire routing and practical access for conductor insertion and screw tightening. The design is suitable for compact board layouts where reliable field wiring connection is required. ## Electrical Description The component is intended for signal and low-voltage power connection applications within the manufacturer’s specified electrical ratings. It provides stable electrical contact when used with compatible conductor sizes, correct wire preparation, and proper screw tightening torque. ## Material and Contact Description The terminal block uses an insulating housing with internal conductive contact elements that transfer current from the inserted conductor to the soldered PCB pins. The screw connection with tension sleeve helps maintain reliable contact pressure and secure conductor retention during normal operating conditions. ## Mounting and Assembly Description The **1727010** is intended for through-hole solder mounting on a printed circuit board. The PCB layout should follow the manufacturer’s recommended hole size, pad pattern, spacing, and soldering guidance. The component should be positioned to allow safe wire insertion, screwdriver access, and adequate clearance from nearby components or enclosure walls. ## Application Suitability The device is suitable for industrial control boards, automation modules, power supply interfaces, relay boards, instrumentation equipment, sensor wiring interfaces, building control systems, communication hardware, and other electronic products requiring secure PCB wire termination. ## Design Considerations The design should account for conductor size compatibility, current requirement, voltage rating, tightening torque, creepage and clearance spacing, solder joint strength, wire routing, and service access. The terminal block should not be used beyond the manufacturer’s specified electrical, mechanical, or environmental limits. ## Hashtags #commonpartslibrary #terminalblock #pcbterminalblock #phoenixcontact #mkds #combicon #wiretoboard #screwterminal #fixedterminalblock #throughholecomponent #soldermount #connector #interconnect #fieldwiring #industrialelectronics #automationequipment #controlsystems #powerinterface #pcbdesign #hardwaredesign #electronicscomponents #electronicparts #engineeringparts #componentlibrary #electronicsengineering
