Overview
The M20-7892846 is a female socket header from the Harwin M20 series, designed for through-hole mounting. It features a 2x14 pin configuration with a 2.54 mm pitch and a 5.08 mm row spacing. The connector utilizes a push-pull locking mechanism and accepts mating pins with a stack height of 9.94 mm, 10.64 mm, or 11.04 mm. Rated for 3 A current and 1000 V voltage, it employs phosphor bronze contacts with gold plating on the mating interface and tin plating on the tail. The housing is constructed from black polyamide (PA6T) nylon, rated UL94 V-0, and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Push-pull locking system ensures secure mechanical retention during mating cycles.
- Gold-plated contact interface provides reliable electrical conductivity and corrosion resistance.
- High-voltage rating supports demanding industrial and telecommunications applications.
Applications
- General purpose electronic interconnects
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify that the specific suffix matches the required contact plating and housing material specifications. Confirm that the mating header stack height aligns with the supported options of 9.94 mm, 10.64 mm, or 11.04 mm. Ensure the design accommodates the through-hole termination style and the physical footprint defined by the 2.54 mm pitch.
Selection Notes
Select this component when high-voltage isolation and robust mechanical locking are required in a compact form factor. The PA6T insulation offers superior thermal stability compared to standard nylons. Verify compatibility with existing PCB layouts regarding the 2x14 pin arrangement and ensure adequate clearance for the push-pull actuation mechanism.
Part Context
This part belongs to the M20 series, a family of connectors known for their modular design and push-pull locking feature. The series offers various configurations including headers, receptacles, and wire housings. The M20-7892846 specifically addresses the need for high-density, high-reliability connections in space-constrained environments requiring frequent maintenance or vibration resistance.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
