1899155

The 1899155 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 PCB Pins - Straight 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 1.572" (39.92mm) 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.The 4 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 - Rear 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 0.200" (5.08mm) 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 10 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 Sealing Gasket, 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.
