Micro-One Wire-to-Board Connectors with ISL

Molex Micro-One Wire-to-Board Connectors with Integrated Independent Secondary Lock (ISL) ensure proper terminal insertion and prevent accidental back-outs. These features allow the Micro-One Wire-to-Board Connectors to achieve secure electrical contact and improved mating retention in high-vibration applications. The series features a 2mm pitch low-profile design and high-reliability UL/CSA-certified connectors. Molex Micro-One with ISL offers 250V maximum voltage, 4A maximum current, and 30 cycles minimum durability.
