Molex Mini-Fit Jr Female Connector Housing, 4.2mm Pitch, 12 Way - 5557 Series - 39-01-2120
This Molex female connector housing from the Mini-Fit Jr series fixes your wires to PCB (printed circuit boards) or makes wire-to-wire connections. The housing connects to 12 compact connectors in two rows, maximising your electrical capabilities in a small space. Using its crimp termination method, the housing pushes over the connection, insulating it from dust and moisture to reduce the risk of electrical interference. This unit can withstand a current capacity of up to 13A (amps) per circuit, so can be used in high-powered applications.
Features & Benefits
• Compatible with other Mini-Fit series connectors such as Mini-Fit Plus HCS (high-current system) crimp terminals
• Audibly clicks when locked in place for clear mating confirmation
• Tested to confirm burning in the unit will cease after 30 seconds for optimum fire safety
• Fully isolated to minimise interference
• Polarised terminals prevent mismating and misalignment
Applications
• Medical technology
• Commercial vehicle equipment
• Consumer devices
• Industrial controls
Does this housing work in extreme temperatures?
