Frequently Asked Questions
How many circuits does the Molex 51242022 connector support and what is the contact pitch?
The Molex 51242022 is a 22-circuit wire-to-board connector with a 2.00 mm pitch between adjacent contacts. This combination of 22 positions and 2.00 mm spacing makes it appropriate for multi-wire cable assemblies in consumer electronics, industrial control boards, and appliance motor controllers where space is limited but a high wire count is needed.
What current rating per contact does the 51242022 support, and how does that affect power distribution?
The Molex 51242022 is rated at up to 3 A per contact, which allows distribution of both logic-level signals and moderate power lines such as 5 V or 12 V motor drive references within the same 22-position connector. At 12 V and 3 A, a single contact can carry up to 36 W, enabling simplified wiring for small actuator or relay coil loads alongside sensor signals.
In what way does the 51242022 differ from Molex PicoBlade or ZH connectors of similar pitch?
The Molex 51242022 uses a 2.00 mm pitch that is larger than the 1.25 mm PicoBlade pitch, providing easier hand assembly and higher current handling of 3 A per contact versus approximately 1 A for PicoBlade. With 22 positions and a positive latch, the 51242022 is better suited for harnessing applications in industrial panels or appliances that require robust mechanical retention rather than the ultra-miniature form factor of sub-2 mm pitch connectors.
