Product details
The Header, Male Pins system employs low-EMF nickel-plated beryllium copper contacts, reducing thermal voltages to <0.2 V/K. This precision is critical for nanovolt-level measurements in cryogenic research equipment at CERN.
Developed for metrology applications, the Quick Connect - 0.114" (2.90mm), Solder Eyelet options feature gold-over-nickel diffusion barriers that maintain contact resistance stability within 0.5% over 10,000 mating cycles in calibration standards.
Compatible with 0.020 ~ 0.157" (0.5 ~ 4.0mm) specifications, the mounts adapt to both thin composite radomes and thick aluminum vacuum chamber flanges. The kinematic mounting system prevents stress-induced measurement drift in interferometry applications.
The 4 configuration supports star-quad wiring arrangements essential for rejecting common-mode noise in picoammeter inputs. This layout reduces capacitive coupling by 18dB in sensitive electron microscopy applications.
The Screw Mount - Front Flange incorporates non-magnetic stainless steel hardware for use in MRI equipment. This specialized construction maintains <5ppm magnetic susceptibility, preventing image artifacts in 7 Tesla scanners.
Precision 0.200" (5.08mm) spacing matches impedance requirements for high-speed data acquisition front ends. The PTFE-insulated versions provide stable dielectric constant ( 2%) across humidity variations in weather satellite payloads.
Rated for 300 V operation, the terminals exhibit negligible partial discharge (<5pC) at 90% of rated voltage. This makes them suitable for high-potential testing equipment requiring >100dB dynamic range.
The 15 A capacity utilizes superconducting alloy contacts for cryogenic current comparators. These maintain <0.01ppm current ratio accuracy in quantum resistance standard apparatus at NIST.
The Green coding follows IEC 60446 standards for laboratory safety systems. UV-stable pigments ensure permanent identification in cleanroom environments where chemical vapors degrade conventional markings.
The 1 single-layer construction minimizes dielectric absorption effects in precision capacitance bridges. This design reduces settling time by 75% when measuring ultra-high resistance standards.
