M20 and M22 Connectors

Harwin M20 and M22 Connectors are 2mm (M22) and 2.54mm (M20) pitch connectors that conform to current conventions for Pin Header and Socket systems. The M20 Series feature 0.64mm² male pins while the M22 series have 0.5mm² male pins. The M20 and M22 sockets feature dual beam contacts with better spring capability than tuning fork contacts. These features offer higher durability, improved repeatable retention, and an improved connection to offer a more reliable connector.
