Component Specifications

Definition
A precision electrical contact component used in Automated Test Equipment (ATE) connectors, designed to establish and maintain secure electrical connections between test instruments and devices under test (DUTs). These components ensure signal integrity, low contact resistance, and durability through repeated mating cycles in high-frequency testing environments.
Working Principle
Works by establishing physical and electrical contact between mating surfaces through spring-loaded or compliant pin/socket designs, ensuring consistent pressure and conductivity. The pin (male) inserts into the socket (female), creating a low-resistance path for electrical signals while maintaining mechanical stability.
Materials
Beryllium copper (BeCu) or phosphor bronze with gold plating (typically 30-50 microinches) over nickel underplating for corrosion resistance and low contact resistance. Insulators made of high-temperature thermoplastics like PEEK or LCP.
Technical Parameters
  • Mating Cycles ≥10,000 cycles
  • Current Rating 1-5A
  • Voltage Rating 250V AC/DC
  • Insertion Force 0.5-2.5N per contact
  • Withdrawal Force 0.3-1.5N per contact
  • Contact Resistance <20 mΩ
  • Operating Temperature -55°C to +125°C
Standards
IEC 60512, MIL-DTL-83513, EIA-364

Frequently Asked Questions

What is the primary function of contact pins/sockets in ATE connectors?

To provide reliable, low-resistance electrical connections between test equipment and devices under test, ensuring accurate signal transmission during automated testing procedures.

Why are gold-plated contacts preferred in ATE applications?

Gold plating provides excellent corrosion resistance, maintains low and stable contact resistance over time, and ensures reliable performance through thousands of mating cycles without oxidation issues.

How do contact pins/sockets maintain consistent electrical performance?

Through precision spring mechanisms or compliant designs that maintain constant contact pressure, compensating for minor misalignments and wear over multiple mating cycles.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
