Overview
The M20-7851742 is a through-hole female socket header from the Harwin M20 series, featuring a 34-position configuration with a 0.100-inch (2.54mm) pitch. Designed for board-to-board or cable applications, it utilizes square contact shapes and gold plating for reliable signal transmission. The connector supports a rated current of 3A per contact and operates within a temperature range of -40°C to 105°C. Constructed with PA6T insulation and brass contacts, it offers UL94 V-0 flammability rating and push-pull locking for secure mating.
Feature Summary
- Push-pull locking mechanism ensures secure connection retention during vibration
- Gold-plated square contacts provide durable low-resistance electrical pathways
- PA6T insulation material delivers high thermal stability and flame resistance
Applications
- Industrial control panel interconnections
- Consumer electronics internal circuit boards
- Automotive electronic module connections
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions maintain contact integrity. Validate mechanical dimensions against PCB footprint requirements to prevent assembly misalignment.
Selection Notes
Select this component when high-density 34-position connectivity is required in space-constrained designs. The through-hole mounting style provides robust mechanical anchoring compared to surface-mount alternatives. Gold plating is suitable for environments requiring corrosion resistance and frequent mating cycles.
Part Context
Part of the M20 series rectangular connectors, designed for general-purpose electronic interconnects. The series emphasizes reliability in harsh environments through standardized dimensional tolerances and material specifications. This specific model represents a mid-range position count option within the broader family.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other M20 series variants only if pin count and pitch match exactly.
