Heavy Duty Connectors consist of 5 parts. 1) Cable Gland 2) Hoods 3) Male or Female inserts 4) Crimp Contacts and 5) Housings. These Rectangular Connectors are available in 12 styles, from the HA series to the HQ series as shown below. The series differ in the number of pin combinations and the power and voltage combinations. Voltage ranges from 50 to 1000 volts and current carrying capacity is from 5A to 100A. Contacts are available as screw terminals, spring terminals or crimp terminals. Heavy Duty Connectors (or Rectangular Connectors) are extensively used in equipment that requires electrical and signal connections, such as construction machinery, textile machinery, package printing machinery, machinery, electrical locomotives and petrochemical electrical equipment. These are internationally recognised standard connectors covered by DIN VDE 0627, DIN VDE 0110, DIN EN 61984 and DIN EN 6198 specifications.
