16 AWG Flexible Heated-Bed Wire Pair – 50cm with Terminals

Pair of flexible 16 AWG wires, one red and one black, prepared for connecting a heated bed to a 3D printer controller board. Each conductor is approximately 50cm long and has a pre-insulated pin terminal fitted to one end for connection to a compatible terminal block.

The wires use stranded tinned-copper conductors with flexible silicone insulation. This configuration is used in our 3DSteel and P3Steel printers, but it can also be used in other machines when the length, wire size, termination and electrical requirements are suitable.

Main features

• Quantity: 2 separate wires.
• Colours: 1 red and 1 black.
• Wire gauge: 16 AWG.
• Approximate nominal cross-sectional area: 1.31mm².
• Length of each wire: approximately 50cm.
• Conductor: stranded tinned copper.
• Insulation: flexible silicone.
• Indicated stranded-conductor diameter: approximately 1.53mm.
• Indicated outside diameter: approximately 3mm.
• One end of each wire has a pre-insulated pin terminal.
• The opposite end is supplied without a bed-specific connector.

Compatibility

• Used in HTA3D 3DSteel and P3Steel printers.
• Suitable for RAMPS electronics with compatible terminal blocks.
• Can be used with certain SKR boards and other controllers when their terminals accept the pin and wire size.
• Can be adapted to other DC heated-bed 3D printers after checking their electrical requirements.

Compatibility with a particular board or printer may be partial. Check heated-bed voltage, power and current, required cable length, controller-output capacity and terminal dimensions. A physically matching connection does not guarantee that the controller can safely drive the load directly.

Heated-bed connection

The pin terminals are intended for the controller side when its terminal blocks are compatible. The opposite end must be terminated according to the bed design, using soldering, a crimp terminal or a dedicated connector as appropriate.

Heated beds can draw substantial current. If the load exceeds the controller output rating, a correctly sized external MOSFET module may be required. This must be determined from the actual specifications of the heated bed and controller board.

Installation recommendations

• Completely disconnect power before working on the circuit.
• Check heated-bed polarity and rated voltage.
• Make sure that the terminals are fully inserted and firmly secured.
• Provide strain relief so that bed movement does not pull directly on the electrical connections.
• Avoid tight bends and continuous rubbing against the machine frame.
• Perform an initial test and check the temperature of the wires, terminals and connectors.
• Periodically check terminal tightness as part of printer maintenance.
