About Rectangular Headers

Rectangular headers are fundamental interconnect components that bridge PCBs to cables, peripherals, or other boards. Their standardized footprints simplify prototyping and mass production, while variations in pin count, orientation, and pitch accommodate diverse layout requirements across electronics.

Quality headers like the MTA-100 series prevent signal degradation and physical failure in vibrating environments. Selecting the correct header type ensures long-term system integrity, reduces maintenance costs, and avoids compatibility issues in upgrades or repairs.

Frequently Asked Questions

Q: What wire gauge is compatible with this header?
A: Compatible wire gauges vary; consult the datasheet for specific current ratings based on your application requirements.

Q: Is this header RoHS compliant?
A: Yes, TE Connectivity designs this series to meet RoHS environmental standards.

Q: Can I use this for high-vibration environments?
A: The friction-lock mechanism provides secure mating suitable for moderate vibration. For extreme conditions, consider supplemental retention.

Q: What’s the difference between shrouded and unshrouded headers?
A: Shrouding (like this header’s 1-wall design) prevents pin damage and incorrect mating alignment during assembly.

Q: Does PCX provide samples before bulk orders?
A: Yes – contact our support team to request samples of this connector.

Q: Are mating connectors included?
A: This is a standalone header; compatible MTA-100 housings (e.g., 1-480699-0) are sold separately.
