Connector Header: Voltage Rating 250V AC/DC

Component Specifications

Definition

A connector header is an electromechanical component designed to establish secure electrical connections between the compensation circuit board and external devices or subsystems. It consists of multiple conductive pins arranged in a specific pattern, housed within an insulating body that provides mechanical support and electrical isolation. This component enables reliable signal transmission, power distribution, and data communication while maintaining circuit integrity in compensation systems.

Working Principle

The connector header operates by providing multiple conductive pathways through precisely aligned pins that mate with corresponding sockets or cables. When engaged, these pins establish low-resistance electrical contacts, allowing current flow and signal transmission between the compensation circuit board and connected components. The insulating housing prevents short circuits and maintains proper pin alignment, while polarization features ensure correct mating orientation.

Materials

Pins: Phosphor bronze or brass with gold/nickel plating (0.4-0.8 um thickness); Housing: High-temperature thermoplastic (PBT, PPS, or LCP) with UL94 V-0 flame rating; Contacts: Beryllium copper springs with tin or selective gold plating

Frequently Asked Questions

What is the difference between male and female connector headers?

Male connector headers have exposed pins that insert into female headers with corresponding sockets. For compensation circuit boards, male headers are typically mounted on the board to connect with female cable connectors or other board connectors.

How do I select the right connector header for my compensation circuit board?

Consider pin count, pitch spacing, current rating, operating temperature, mounting type, and environmental requirements. Match the header specifications to your circuit's electrical needs and mechanical constraints.

Can connector headers be used in high-vibration environments?

Yes, with proper locking mechanisms or retention features. Look for headers with positive locking clips, friction locks, or screw mounting options for vibration-resistant applications in industrial settings.
