Frenquently Asked Questions
Technical FAQs
Q1: What wire gauge fits M2051R-N feed through IDC?
A: Designed for AWG22~26 discrete single conductors, standard 2.54mm pitch.
Q2: What are the differences in Application: With vs Without Polarizing Tabs?
Answers are below:
①With Polarizing Tabs
Features integrated polarization tabs that ensure correct mating orientation.
Prevents incorrect insertion and reduces the risk of miswiring or connection errors.
Recommended for applications where reliable, error-free assembly is critical.
Available with integrated polarization tabs to prevent incorrect mating and ensure proper connector orientation during assembly
②Without Polarizing Tabs
Standard connector design without polarization features.
Offers greater mating flexibility but requires proper alignment during installation.
Suitable for applications where connector orientation is clearly identified and the risk of mis-mating is low.
Non-polarized versions are also available for applications where keying is not required.
Note: Electrical & IDC crimp performance are identical for both versions.
Q3: Can this IDC mate with PCB header directly?A: Indirect PCB connection only, pair with M2545 vertical and M2545R right angle PCB header for wire-to-board assembly.
Q4: Is matching protective cover available?A: Compatible with M2053 series cover to shield pins from dust, moisture and debris.
Q5: Material & flammability grade of insulator housing?A: UL94V-2 flame retardant nylon; tin-plated copper alloy contacts, RoHS compliant.
Q6: Can it realize middle-of-cable feed-through daisy chain wiring?A: Yes, feed-through structure allows continuous in-line wiring without cutting finished harness.
Q7: What are the advantages of a 90° IDC Closed End connector?
A: Key benefits include:
Higher mechanical reliability due to internal cable termination and reduced stress on IDC contacts.
Compact cable routing, requiring cable exit space on only one side.
Improved signal integrity with minimal cable stubs and reduced signal reflections.
Simplified assembly, as the cable is terminated at a single location.
Typical applications: Point-to-point cable assemblies, control systems, power distribution modules, and industrial equipment.
Q8: Which connector type should I choose, closed end IDC or Feed through IDC?
A: Selection depends on your application requirements:
| Application | Recommended Connector |
|---|
| Point-to-point connections | 90° IDC Closed End |
| Space-constrained designs | 90° IDC Closed End |
| High-vibration environments | 90° IDC Closed End |
| Daisy-chain wiring | 180° IDC Feed through |
| Multi-board systems | 180° IDC Feed through |
| Bus or distributed I/O architectures | 180° IDC Feed through |
| Cost-sensitive cable assemblies | 180° IDC Feed through |
Order FAQs
Q1: Available pin counts for M2051R-N series?
A: Standard range from 2P to 24P, customized pin positions negotiable upon bulk order.
Q2: What’s your MOQ for regular stock items?A: Small MOQ for in-stock specs; customized color/spec needs higher minimum order quantity.
Q3: Lead time for sample & mass production?A: Samples ship within 1~3 working days; bulk orders around 7~15 working days based on quantity.
Q4: Can we customize housing color or contact plating?A: Custom black/other housing color, gold plating contacts available for large-volume orders.
Q5: Are free samples available for customer test?A: Free small quantity samples offered, buyer covers international courier freight.
