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 C13 Locking (A-Lock)

IEC 60320 C13 Locking (A-Lock)

General Information:

The IEC 60320 C13 is a grounded 3 Wire connector rated up to 250V and 15 Amps. The C13 mates with a C14 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. Most people know the C13 as 'the thing that plugs into my computer' because it is the standard connector used to power most desktop computers. In a desktop computer application, the most common cable is the NEMA 5-15P to C13, which connects your standard North American wall outlet to a desktop computer. The A-Lock feature can be used on any standard C14 inlet, it can be disconnected by pulling back on the red tabs on the side of connector head.

What does the IEC 60320 C13 Auto Lock Connect to?



IEC 60320 C14 Plug		IEC 60320 C14 InletThe IEC 60320 C13 Auto Lock is a universal locking connector. This means that it can be connected to any standard IEC 60320 C14 Plug or Inlet.
