1250940000

The 1250940000 by Weidmüller 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 Bolt/Screw Clamp - Wire Entry 90° to Panel 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 Bolt/Screw Clamp - Wire Entry 90° to Panel 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 0.319" (8.10mm) 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 ~ 0.157" (1.0 ~ 4.0mm) 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 1 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 2 Piece 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.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 30 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.Supporting 10-30 AWG ranges, these terminals accommodate both 40AWG microcoax for timing signals and 8AWG power distribution cables. The dual-material strain relief prevents cold flow in superconducting magnet feeder systems.The Black 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.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.
