IP code. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical ...
Water Resistant mark. Water Resistant is a common mark stamped on the back of wrist watches to indicate how well a watch is sealed against the ingress of water. It is usually accompanied by an indication of the static test pressure that a sample of newly manufactured watches were exposed to in a leakage test. The test pressure can be indicated ...
Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. Water-resistant and waterproof often refer to resistance ...
D-subminiature. Normal density of DA, DB, DC, DD, and DE sized connectors. The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Normal density.
Classification. There are three general types of rugged phone: Outdoor sports; Military; Stylish; Functional requirements. The following IP code ratings for ingress protection (IP), as defined by the International Electrotechnical Commission (IEC) standard 60529 (equivalent to European standard EN 60529), are typically used for certifying various toughened and ruggedised smartphones.
IEC 60309-2 connectors come in IP44 (splash-proof), IP67 (waterproof) and IP66/IP67 (jet-proof/waterproof) variants. In all cases, the rating applies when detached or mated, but not during the mating process. The more common IP44 variant features a spring-loaded hinged cap over the socket.
Internetwork Packet Exchange. Internetwork Packet Exchange ( IPX) is the network layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems ' IDP. It also has the ability to act as a transport layer protocol. The IPX/SPX protocol suite was very popular through the late 1980s and mid-1990s because it was used by ...
IPX is a network-layer protocol (layer 3 of the OSI model ), while SPX is a transport-layer protocol (layer 4 of the OSI model). The SPX layer sits on top of the IPX layer and provides connection-oriented services between two nodes on the network. SPX is used primarily by client–server applications. IPX and SPX both provide connection ...
