12 Position Printed Circuit Board Connector

Phoenix Contact 1786271 is a 12-position pluggable terminal block connector for printed circuit boards (PCBs). It is rated for a nominal current of 12 A and a voltage of up to 320 Volts AC. This connector features a 5.08 mm pitch and utilizes a screw connection system, accommodating wire sizes ranging from 12 to 30 AWG (0.2–2.5 mm²). Thanks to its maximum contact force, this connector has a low temperature rise.

Benefits:

• Well-known connection principle allows worldwide use
• Easy PCB replacement thanks to plug-in modules
• Inverted connector with pin contacts for touch-proof device outputs or free-hanging cable/cable connections
• Can be combined with the MSTB 2,5 range
• Low temperature rise, thanks to maximum contact force
