Offering a wide range of standard spring contact probes to meet your testing requirements and has long been recognized as the world’s largest probe manufacturer. With over 60 different probe series ranging from 0.02" (0.51 mm) to 0.187" (4.75 mm) pitch with multiple length, travel, ICT, lead free and rotator options, we provide a full portfolio designed for general purpose test on bare boards, loaded printed circuit boards and surface mount assemblies.
Spring probes are designed to optimize performance in high reliability, multicycle applications. Spring probes are compliant which makes them ideal for blind mate applications as they selfcorrect for x, y, z, rotational and angular misalignment of the target.
In-house capabilities encompass design, development, manufacturing and testing. Providing operational excellence tailored to volume manufacturing requirements, global sourcing, world class engineering talent and rapid prototyping.
The SH Series features a bias ball, which is the most aggressive biasing technique to aid in assuring a low and consistent resistance, cycle after cycle. The SHE Series features a bias spring, an effective biasing technique for many applications.
Standard probe series for 0.039" (1.00 mm) pitch includes multiple length, travel, ICT, lead free and rotator options. ICT probe designs feature a bifurcated barrel with four separate fingers. The barrel is compliant and formed against the plunger, thus eliminating any gap between the plunger and barrel. ICT probes are more accurate and stable in resistance than standard designs.
Standard probe series for 0.050" (1.27 mm) pitch includes multiple length, travel, ICT, lead free and rotator options. ICT probe designs feature a bifurcated barrel with four separate fingers. The barrel is compliant and formed against the plunger, thus eliminating any gap between the plunger and barrel. ICT probes are more accurate and stable in resistance than standard designs.
Standard probe series for 0.075" (1.91 mm) pitch includes multiple length, travel, ICT, lead free and rotator options. ICT probe designs feature a bifurcated barrel with four separate fingers. The barrel is compliant and formed against the plunger, thus eliminating any gap between the plunger and barrel. ICT probes are more accurate and stable in resistance than standard designs.
Standard probe series for 0.100" (2.54 mm) pitch includes multiple length, travel, ICT, lead free and rotator options. ICT probe designs feature a bifurcated barrel with four separate fingers. The barrel is compliant and formed against the plunger, thus eliminating any gap between the plunger and barrel. ICT probes are more accurate and stable in resistance than standard designs.
Standard probe series for 0.125 (3.18) pitch includes multiple length and travel options. Smiths Interconnect offers a wide range of Spring Contact Probes to meet your testing needs and has been recognized as a world leading provider for over 40 years.
Standard probe series for 0.156" (3.96 mm) and 0.187" (4.75 mm) pitches includes multiple length and travel options. Smiths Interconnect offers a wide range of Spring Contact Probes to meet your testing needs and has been recognized as a world leading provider for over 40 years.
Standard probe series for 0.187" (4.75 mm) and 0.300" (7.62 mm) pitches includes multiple length and travel options. Smiths Interconnect offers a wide range of Spring Contact Probes to meet your testing needs and has been recognized as a world leading provider for over 40 years.
The Micro Probe Series ranges in pitch from 0.20" (0.51 mm) to 0.030" (0.76 mm) and are typically between 0.50" to 1.00" in length. Smiths Interconnect offers a wide range of Spring Contact Probes to meet your testing needs and has been recognized as a world leading provider for over 40 years.
Smiths Interconnect offers the industry's most extensive line of high reliability coaxial probes. Our coaxial probes provide a low noise, controlled impedance signal path with reliable and easy connect/disconnect options.
Offering two types of wireless receptacles, the R-100, R-075 and R-50C receptacles house a replaceable probe on the top end and have a permanent probe on the bottom end. These receptacles are designed for mixed center PCB test. The R-100/SS and R-SS/SS receptacles have replaceable probes on both sides and are designed for more general purpose wireless connections.
Double-ended probes feature both a top-side and bottom-side compliant plunger. Double-ended receptacles are available with a permanent bottom-side plunger and a replaceable probe on the top side. They are also available with both a top and bottom-side replaceable probe.
Switch Probe is a spring contact probe and receptacle combination that is normally open, and after a designated travel the switch probe closes. The most common use for switch probes is in the cable harness testing industry. The switch probe is used to verify the correct location of a terminal in a connector while checking the retention force as well. Switch probes also verify the presence of nonconductive components such as caps for connectors or devices on a circuit board. Smiths Interconnect offers three standard sizes of switch probes.
Thermocouple probe is an ungrounded, thermally conductive probe used for the measurement of variations in temperature.The thermocouple probe's unique design ensures that the wires are internally fixed. This is done to prevent the two thermocouple wires from becoming dislodged from the plunger head cavity. This result is increased durability, which extends the service life of the probe.
Interface probes for all major test equipment manufacturers. We also provide a variety of interface pins for use in test fixtures.
Smiths Interconnect is a leading provider of technically differentiated electronic components, subsystems, microwave and radio frequency products that connect, protect and control critical applications in the commercial aviation, defense, space, medical, rail, semiconductor test, wireless telecommunications, and industrial markets.
