Overview
Smiths Interconnect offers a comprehensive range of spring contact probes designed for various testing requirements, recognized as the world's largest probe manufacturer. The document outlines different types of probes, their specifications, and applications.

Micro Series Probes
The Micro Series Probes have a pitch range from 0.20” (0.51 mm) to 0.030” (0.76 mm) and are typically between half an inch to an inch in length.

Rotator Probes
These probes are ideal for non-clean and lead-free applications, featuring a 90° rotation at rated travel to effectively penetrate contaminants with low spring force.

Standard Probes
Standard probes range in pitch from 0.039” (1.00 mm) to 0.187” (4.75 mm) with multiple length and travel options, including aggressive probes dimensionally equivalent to standard ones.

High Current Probes
Available in two designs across four pitches, the SH series uses a bias ball for low resistance, while the SHE series uses a bias spring.

Double-Ended Probes & Receptacles
These feature compliant plungers on both sides, with options for permanent or replaceable probes.

Switch Probes
Switch Probes have two current paths, one closed and one open, with the second path closing after a designated travel.

Lead Free Probes
Based on the ICT Probe Series, these probes are optimized for less wear and contamination with a moderate spring force.

Thermocouple Probes
Ungrounded, thermally conductive probes for temperature measurement, available in Type T (up to 220°F) and Type K (up to 350°F).

ICT Probes
Featuring a bifurcated barrel for improved accuracy and stability in resistance.

Coaxial Probes
Provide a low noise, controlled impedance signal path with easy connect/disconnect options.
