Micro-Lock Plus Connectors

Molex Micro-Lock Plus Wire-to-Board Connectors provide electrical and mechanical reliability in high-temperature designs that meet automotive and other industry requirements. These connectors are 1.25mm, 1.5mm, and 2mm pitch connectors with positive lock, delivering secure mating retention without sacrificing compactness. The micro-lock plus connectors operate at a temperature range of -40ºC to 105ºC, which can resist harsh environments. These connectors feature robust metal solder tabs and a wide positive latch that delivers an audible click. The 1.25mm version features a dual-contact terminal design. These connectors are used in automotive, power for data centers, and appliances.
