Component Specifications

Definition
A precision electrical connector designed specifically for instrumentation modules such as Digital Multimeters (DMMs) and oscilloscopes, facilitating the transmission of measurement signals, control commands, and power between the instrument and external devices, test fixtures, or data acquisition systems. These connectors ensure reliable signal integrity with minimal noise interference in industrial measurement applications.
Working Principle
Operates by providing a secure mechanical and electrical interface that maintains consistent contact resistance and impedance matching. The connector establishes multiple conductive pathways (pins/sockets) that carry analog/digital signals, power, and ground connections while preventing signal degradation through proper shielding and contact design.
Materials
Contacts: Beryllium copper or phosphor bronze with gold plating (0.5-2.0μm); Housing: High-temperature thermoplastic (PBT, PPS, or LCP) with UL94 V-0 rating; Insulators: Glass-filled nylon; Shielding: Nickel-plated steel or aluminum; Seals: Silicone rubber (for environmental protection).
Technical Parameters
  • IP Rating IP67 (when mated)
  • Impedance 50Ω or 75Ω (RF versions)
  • Mating Cycles ≥500 cycles
  • Current Rating 5A per contact
  • Voltage Rating 250V AC/DC
  • Contact Resistance <20mΩ
  • Insulation Resistance >1000MΩ
  • Operating Temperature -40°C to +85°C
Standards
IEC 61076-2, MIL-DTL-38999, ISO 9001

Frequently Asked Questions

What types of signals can I/O connectors for instrumentation modules handle?

These connectors can handle analog measurement signals (voltage, current), digital communication protocols (GPIB, USB, Ethernet), trigger signals, and power supply connections, with specific versions optimized for high-frequency or high-voltage applications.

How do I ensure proper mating and unmating of these connectors?

Always follow the manufacturer's orientation guides, apply even pressure during mating, and use the appropriate extraction tool if provided. Avoid twisting or forcing the connection, and regularly inspect contacts for contamination or damage.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
