IEC 60309 includes “plugs, socket-outlets and couplers for industrial purposes”. The IEC 60309 standard puts an emphasis on safety through a unique arrangement of pins and earth/ground to ensure that only compatible devices are able to mate. Further, this standard may optionally include a pilot contact that plugs in last when connecting and first when disconnecting to reduce the likelihood or arcing, which may cause damage to the individual or device. The pin and sleeve design of this standard provides some degree of weatherproofing, indicated by its IP (Ingress Protection) marking. Most common are the IP44 and IP66, which provide splash-proof protection and watertight protection, respectively. Overall, this standard is common in open-air conditions where high power draw is required and protection from individuals, dust, water and chemicals is desired.

IEC 60309 320P6 IP44 Splashproof Plug

General Information:

IEC 60309 includes “plugs, socket-outlets and couplers for industrial purposes”. The IEC 60309 standard puts an emphasis on safety through a unique arrangement of pins and earth/ground to ensure that only compatible devices are able to mate. The pin and sleeve design of this standard provides some degree of weatherproofing, indicated by its IP (Ingress Protection) marking.  

IP44 is known as the "Splashproof" Rating, which breaks down to sealing against solids no smaller than 1.0mm and spraying water at the connection from any angle. Overall, this standard is common in open-air conditions where high power draw is required and protection from individuals, dust, water and chemicals is desired. The IP code, as defined by standard IEC 60529, classifies the degrees of protection provided against the intrusion of solids and liquids.

IEC 60320 C19 A-Lock

IEC 60320 C19 A-Lock

General Information:

The IEC 60320 C19 is a grounded 3 Wire connector rated up to 250V and 20 Amps. The C19 mates with a C20 inlet, and is commonly used in a jumper cable scenario in IT Installations providing power from a PDU to a server, router, switch or other computing device. The C19 is typically used in high powered blade server chassis, large network routers, and other IT equipment that draws more power than a standard C13 can accommodate. The A-Lock feature can be used on any standard C2 inlet, it can be disconnected bu pulling back on the red tabs on the side of connector head.

What does the IEC 60320 C19 Auto Lock Connect to?




IEC 60320 C20 Plug		IEC 60320 C20 InletThe IEC 60320 type C19 connector is designed to connect to the IEC 320 C20 plug and Inlet. THE C20 Plug is commonly found on power cords used in the data center industry. The C20 Inlet can be found on a variety of high powered IT Equipment ranging from switches to Un-Interrupted Power Supply systems.
