The 1861251 by Phoenix Contact represents a breakthrough in Terminal Blocks - Panel Mount for high-energy physics experiments. Engineered for CERN-grade reliability, these terminal blocks withstand extreme radiation levels while maintaining signal integrity in particle detector readout systems.The Header, Male Pins system uses radiation-hardened tungsten-rhenium alloys that resist embrittlement up to 10^16 neutrons/cm . This durability ensures stable operation in ATLAS pixel detector service panels exposed to LHC beam conditions.Designed for cryogenic tracking systems, the Quick Connect - 0.187" (4.75mm), Solder Eyelet options feature ceramic-insulated silver-palladium contacts that maintain <1m resistance at 1.9K. This performance is essential for silicon strip detector interconnects in CMS upgrades.Available in 4.199" (106.66mm) configurations, these terminals enable high-density routing in trigger electronics crates. The 4mm pitch version supports 1024-channel readout ASICs while maintaining 100V isolation in hadron calorimeter front-end boards.Compatible with 0.039 ~ 0.197" (1.0 ~ 5.0mm) specifications from 1mm to 10mm, the mounts adapt to both thin carbon fiber supports and heavy lead-tungsten shielding blocks. The non-magnetic titanium hardware prevents field distortions in spectrometer regions.The 12 matrix matches silicon pixel module geometries. This layout simplifies detector module replacement in ALICE inner tracking system maintenance procedures without requiring complete system rewiring.The Screw Mount - Front Flange incorporates non-outgassing adhesives that meet CERN's ultra-high vacuum standards. The stainless steel hardware reserves magnetic permeability <1.01 for use in solenoidal magnetic fields up to 4T.Precision 0.300" (7.62mm) spacing prevents discharge in liquid argon time projection chambers. The radiation-resistant PEEK insulation maintains dielectric properties after 500kGy ionizing dose exposure in neutrino detector electronics.Rated for 300 V operation, the terminals withstand 2kV pulses from photomultiplier tube arrays. This ruggedness is critical for handling signal transients in Cherenkov detector trigger systems.The 20 A capacity handles 100A quench protection currents in superconducting dipole magnets. The explosive-welded copper-aluminum interfaces maintain <10 contact resistance during fast discharge events.The Green coding uses radiation-stable inorganic pigments that withstand 10MGy total ionizing dose. The markings remain legible throughout the 20-year operational life of LHCb vertex locator subsystems.Incorporating Threaded Mating Lock, this series implements Faraday cage shielding for sensitive front-end electronics. The continuous EMI protection reduces noise pickup below 0.1mV in muon spectrometer drift tube readout chains.The 1 single-plane construction minimizes material budget in particle tracking systems. This design contributes <0.1% X radiation length per layer in forward calorimeter signal transmission paths.
