Q1: Which crimp terminals are compatible with the 5055650801 housing?
A: This housing is designed to be used with the Molex 505567 series female crimp terminals. Depending on your wire size, you can choose terminals that support 26 to 30 AWG wires. Please ensure the terminals are fully seated until you hear a “click” to engage the internal locking mechanism.
Q2: Does the 1.25mm pitch Micro-Lock PLUS system provide enough security for high-vibration applications?
A: Yes, it does. Unlike standard friction-fit connectors, the 5055650801 features a positive latch holder that provides a secure mechanical lock with an audible click. This ensures the connection remains stable even in environments subject to constant vibration, such as industrial robotics or automotive electronics.
Q3: What is the benefit of the PBT material used in this connector?
A: The housing is made of Polybutylene Terephthalate (PBT), which offers excellent thermal stability and chemical resistance. It allows the connector to operate reliably within a wide temperature range of -40°C to 105°C, making it suitable for demanding industrial and outdoor applications.
