Key Features
- 24-position dual-row female contact array at 2.00 mm pitch with phosphor bronze contacts for high resilience and reliable spring force retention over 500+ mating cycles
- Tin (Sn) over nickel (Ni) contact finish balances cost-efficiency with corrosion resistance, suitable for industrial and consumer PCB wiring harness applications
- Compact body dimensions of 0.197" x 0.618" x 0.21" enable dense connector population on space-constrained boards without sacrificing extraction force
Applications
The M20-7920242R is widely used in industrial automation wiring harnesses, robotics joint controllers, and consumer electronics sub-assemblies where a 24-way 2.00 mm pitch female connector provides reliable board-to-cable mating. Its phosphor bronze contacts and tin-nickel finish suit designs requiring hundreds of mating cycles in environments with moderate humidity and temperature variation. The connector is also found in medical device sub-assemblies and test jigs where consistent contact force maintains low resistance over repeated connections.

Frequently Asked Questions
What contact material and finish does the M20-7920242R use, and how does that affect corrosion resistance?
The M20-7920242R uses phosphor bronze contacts plated with tin (Sn) over a nickel (Ni) barrier. Nickel acts as a diffusion barrier preventing tin migration into the base metal, while tin provides a low-cost solderable and corrosion-resistant surface rated for industrial environments up to 85°C and 85% relative humidity.
How does the 24-position dual-row layout of the M20-7920242R fit into a 2.00 mm pitch wiring harness?
The dual-row configuration places 12 contacts per row at 2.00 mm pitch, yielding a connector body measuring 0.618" in length. This footprint is compatible with standard 2.00 mm pitch male headers on PCBs or wire-to-board connectors, allowing 24-wire harnesses to terminate in a single housing and reducing assembly time compared to using two 12-pin single-row connectors.
For a robotics joint controller that disconnects the arm module during maintenance, is the M20-7920242R rated for enough mating cycles?
Harwin M20 series connectors are rated for a minimum of 500 mating cycles with tin-plated contacts. A robotics joint module disconnected 5 times per week for two years of maintenance accumulates approximately 520 cycles, which falls at the rating boundary. For higher frequency replacement or maintenance schedules exceeding 1000 cycles, Harwin's gold-plated M20 variants or the M80 series at 2.00 mm pitch are better alternatives.
