The 8.5 amp, 516 series, connectors are available in five circuit sizes 20, 38, 56, 90 and 120. The 56 circuit version of the EDAC 516 connector series with EMI/RFI shielding device and metal cover ~ types plug and receptacle are as shown below with either actuating screw or locknut. The superbly engineered, 8.5 Amp tuning fork type hermaphroditic contact is available with crimp; solder eye; pcb or wire wrap tail.
At the heart of the 516 series design is the gold-plated hermaphroditic contact with four gas-tight, mating surfaces with a long wiping length for self-cleaning as shown below (this helps to alleviate the chance of any increased electrical resistance).
In addition to the excellent heat dissipation characteristics of the contact, the inherent ‘spring’ design also ensures that if contact pressure from two surfaces is reduced for any reason, the pressure on the other two surfaces is proportionally increased. This is very relevant when the connector is used in high shock/vibration applications like Off-Shore wind turbines.
This exceptional contact design has a forty-plus year pedigree of outstanding reliability and performance in numerous safety and mission-critical applications including oil and gas processing, off-shore alternative energy production and railway signalling. EDAC Series 516 are even incorporated into sensor devices installed in the CERN European nuclear physics project.
