Product catalog summary

Document Overview

This technical document provides detailed specifications, configurations, and recommendations for a series of electrical contact probes and sockets with various pitch lengths and tip types. It includes data on mechanical properties, materials, plating, current ratings, and suitable applications for each series.

1. Series and Pitch Lengths

The document categorizes probe and socket series by pitch length, ranging from 4.75mm down to 0.45mm. Each pitch length corresponds to a specific series code (e.g., SW for 4.75mm, SG for 2.54mm, SE for 2.54mm 24.5mm length, etc.) and is detailed on specific pages.

2. Tip Types and Applications

  • Flat and Inverse Cone Tips (S〇-3 series): Flat tips prevent damage to electrical pads and are suitable for surface contact; inverse cone tips are designed for receiving contact tips.
  • 3 Edge Chisel Tips (S〇-4 series): Ideal for through-hole PCB applications.
  • Crown Tips (S〇-5 series): Suitable for multipoint contacts and contact-mounted part leads.
  • Round Tips (S〇-1 series): Designed for flexible PCBs with minimal pad damage.
  • Needle Tips (S〇-2 series): Suitable for PCB pads.

3. Mechanical Specifications

Each series specifies spring force, stroke (used and full stroke), and initial compression values. For example:

  • At 4.75mm pitch: Initial stroke 7.7mm, used stroke 12mm, spring force ranges from 60g to 405g.
  • At 2.54mm pitch: Initial stroke 2.9mm, used stroke 4.3mm, spring force varies by model (EA to ED) from 20g to 40g.
  • Smaller pitches (down to 0.45mm) have correspondingly smaller strokes and spring forces, reflecting finer mechanical tolerances.

4. Materials and Plating

Materials primarily include Beryllium Copper (BeCu) and SK steel, with plating options such as Nickel (Ni), Gold (Au), and Rhodium (Rh). The choice of material and plating depends on the series and intended application, balancing conductivity, durability, and corrosion resistance.

5. Electrical Ratings

Current ratings vary by pitch size, for example:

  • 4.75mm pitch: 5A
  • 2.54mm pitch: 4A
  • 1.27mm pitch: 3A
  • 0.5mm pitch: 1A
  • 0.45mm pitch: 0.5A

This indicates that larger pitch probes can handle higher currents.

6. Probe and Socket Line-ups

The document details probe and socket configurations, including barrel, spring, and receptacle components, with specific material and plating combinations. It also covers variations such as wire crimping types, lead wire lengths (100mm and 300mm), and soldering types.

7. Reference Hole Diameters

Each pitch and series specifies a reference hole diameter for mounting or insertion, ranging from approximately 3.55mm for larger pitches down to 0.39mm for the smallest pitches.

8. Additional Features and Variants

  • Back taper and U-bend types for soldering and wrapping applications.
  • Clip and wire crimping types for lead wire connections.
  • Bias probes, relay pins, and double-headed probes for specialized applications.
  • Flange enlargement (trumpet-shaped) designs for certain pitch sizes.

Critical Information and Best Practices

  • Select tip types based on PCB type and contact requirements to minimize damage and ensure reliable connections.
  • Match spring force and stroke specifications to application needs to maintain contact integrity without excessive wear.
  • Choose appropriate materials and plating to balance electrical performance and mechanical durability.
  • Observe current ratings relative to pitch size to prevent overheating or failure.
  • Use specified reference hole diameters for proper mechanical fit and electrical contact.

Summary

This document serves as a comprehensive guide for selecting and specifying electrical contact probes and sockets across a wide range of pitch sizes and applications. It provides essential mechanical, electrical, and material data to ensure optimal performance and reliability in PCB testing, connection, and assembly processes.
