Product Description
The Hirose DF51-20DS-2C is a female crimp connector housing engineered for precise wire-to-board connections, making it ideal for integration in office automation, industrial machinery, robotics, amusement, and medical equipment. Its dual-row, 20-way configuration allows signal distribution in a compact footprint, facilitating high-density designs in printed circuit board assemblies.
With a 2 mm pitch and straight orientation, the DF51-20DS-2C supports flexible cable mounting and ensures compatibility with a wide range of wire gauges (22 to 30 AWG). The positive locking mechanism delivers clear tactile feedback while physically securing the connector, minimizing risks of incomplete mating and accidental disconnects in vibration-prone environments.
The connector housing is made from polyamide, offering robust mechanical strength while maintaining a light weight. The side-locking design further enhances reliability, while visual and mechanical polarization prevents reverse or incorrect mating with other connectors, safeguarding system integrity.
This model is compatible with DF51 series connectors and common crimping tools, enabling simple and efficient assembly. It is suitable for potting up to 3 mm, supporting additional environmental protection or insulation as needed. Gold and tin plating options (not included in this housing) can be applied to contacts for extended durability and improved conductivity, depending on the terminal selection.
Typical industrial use cases for the DF51-20DS-2C include automation equipment wiring, PCB interconnections in manufacturing controls, industrial robots, and devices requiring reliable wire harness solutions. The compact dimensions of 31 mm length by 10.7 mm width support low-profile designs and dense component placement, especially where space constraints exist.
The connector is not supplied with contacts; these must be specified separately based on application requirements. Explore Hirose's range of connector housings for advanced electronic integration in the Electronics & Electricals category on EnvMart.
