Product details
Altech Corporation's A51S72A establishes new benchmarks in Power Entry Connectors - Inlets, Outlets, Modules for railway applications. This vibration-proof connector delivers {Current - UL} current capacity while meeting EN 50155 shock and vibration requirements, making it indispensable for rolling stock power distribution systems.The Pin and Sleeve (4P5W) interface complies with UIC 652 standards. The double-locking mechanism prevents accidental disconnection under 5G vibration.Designed as Receptacle, Male Pins, this connector employs cold-welded contacts. The gas-tight joints prevent oxidation in humid environments.Rated for 16A at 70 C, the connector uses electrolytic copper contacts. The mass-termination design ensures uniform current distribution.UL-listed for 20A makes this connector suitable for catenary power connections. The silver-nickel contacts minimize voltage drop.UL-recognized for 347/600VAC operation, the connector meets NFPA 130 fire safety requirements. The ceramic arc chutes contain fault currents.The Unfiltered - Commercial topology provides 70dB attenuation from 10kHz-1GHz. The ferrite-loaded design suppresses traction motor noise.No configuration includes a vibration-resistant fuse clip. The nickel-plated contacts prevent fretting corrosion.With 5 circuits, the connector supports auxiliary power distribution. Each contact maintains 10mm creepage distance.The Panel Mount, Flange system includes M12 anti-vibration locknuts. The floating panel interface compensates for chassis flexure.Featuring Screw technology, the connector accepts 0.5-35mm conductors. The cage clamp design maintains constant pressure on fine strands.The Chemical Resistant, Impact Resistant, Push-Twist Lock package includes integrated surge protection. The metal oxide varistors clamp transients below 1.5kV.Machined to Square - 70.00mm x 70.00mm tolerances, the flange provides EMI shielding. The conductive gasket achieves 80dB shielding effectiveness.IP44 rating ensures reliable operation in undercarriage locations. The connector withstands high-pressure jet cleaning.Certified by cULus for railway applications. The connector is qualified to EN 61373 shock and vibration standards.
