SPRING PROBES For Board Test ApplicationsBOARD TEST SPRING PROBES Smiths Connectors offers a wide range of spring contact probes to meet your testing requirements and has long been recognized as the worlds largest probe manufacturer. With over 60 different probe series that includes our standard Board Test Fixture Probes as well as our Specialty Test Probes, we provide a full portfolio designed for general purpose test on bare boards, loaded printed circuit boards, surface mount assemblies and other forms of test. MICRO SERIES PROBES SWITCH PROBES The Micro Probe Series range in pitch from 0.20 (0.51 mm) to A Switch Probe is a spring contact probe and receptacle that has 0.030 (0.76 mm) pitch and are typically between half an inch to two individual current paths. One current path is closed, the other is an inch in length. open and after a designated travel the second current path closes. STANDARD PROBES DOUBLE-ENDED PROBES & RECEPTACLES Our standard probes range in pitch from 0.039 (1.00 mm) Double-ended probes feature both a top-side and bottom-side to 0.187 (4.75 mm). Within most series, there are multiple compliant plunger. Double-ended receptacles are available with length and travel options, including more aggressive probes a permanent bottom-side plunger and a replaceable probe on the dimensionally equivalent to the standard probes. top side. They are also available with both a top and bottom-side replaceable probe. ICT PROBES HIGH CURRENT PROBES The ICT probe design features a bifurcated barrel with four We offer two different high current probe designs in four different separate fingers. The barrel is compliant and formed against the pitches. The SH Series features a bias ball, which is the most plunger, thus eliminating any gap between the plunger and barrel. aggressive biasing technique to aid in assuring a low and consistent ICT probes are more accurate and stable in resistance than resistance, cycle after cycle. The SHE Series features a bias spring, standard designs. an effective biasing technique for many applications. LEAD FREE PROBES THERMOCOUPLE PROBES The Lead Free Probe Series is based on our ICT Probe Series. The Thermocouple Probe is an ungrounded, thermally conductive The plunger material, plating and tip geometry have been probe used for the measurement of variations in temperature. We optimized to provide less wear and contamination build-up while offer two Thermocouple Probes: Type T for up to 220F, and Type K using a moderate spring force of 7 to 8 ounces. for up to 350F. ROTATOR PROBES COAXIAL PROBES Ideal for non-clean and lead-free applications, this aggressive Our Coax Probes provide a low noise, controlled impedance signal probe rotates 90 at the rated travel, virtually drilling through path with reliable, easy connect/disconnect options. Our designs contaminants with a low spring force. include a spring-loaded signal probe and a spring-loaded shielding plunger for the ground.
