What Is a Concrete Nail Clip? Clip Numbers and Selection Criteria — A concrete nail clip is a fastener made of a plastic body that grips the cable and a steel nail, fixing surface-mounted cable to concrete without drilling. What Are HDMI Splitters, Extenders and Converters? Types and Selection Criteria — Video and audio connection accessories distribute an HDMI signal to several displays, carry it further or convert it to interfaces such as VGA, DisplayPort and USB-C. What Is a Transparent-Cover MCB Enclosure? Types and Selection Criteria — A transparent-cover MCB enclosure is a plastic distribution box that houses modular devices such as circuit breakers and RCDs so they can be seen without opening the cover. What Is Galvanized Spiral Conduit with Pull Wire? Types and Selection — Galvanized spiral conduit with pull wire is an uncoated, flexible galvanized steel cable protection conduit with a cable-pulling wire placed inside during manufacture. What Is a Stainless Steel Cable Gland? Types and Selection Criteria — A stainless steel cable gland is a corrosion-resistant metal gland that clamps the cable with its seal and closes a panel or machine entry tightly. What Is a Mini Spring Connection Terminal Block? Push-in and Spring Types, Selection Criteria — A mini spring connection terminal block clamps the conductor by spring force instead of a screw and takes up little rail space thanks to its small housing. What Is a Cable Gland Flat Washer? Sizes and Selection Criteria — A cable gland flat washer is a flat seal fitted on the threaded neck of a cable gland that forms a flat sealing surface between the gland body and the enclosure. What Is a Fan Filter? Types and Selection Criteria — A fan filter is a grilled frame fitted in front of a panel fan or air opening to trap dust; a filter fan combines the fan, filter and grille in one housing. What Are RJ45, F and BNC Connectors? Types and Selection Criteria — RJ45, F and BNC connectors terminate the ends of network (Ethernet) and coaxial (satellite, TV, camera) cables to connect them to devices, wall outlets or patch panels. What Is an Adhesive Cable Clip? Types and Selection Criteria — An adhesive clip is a plastic base fixed to a flat surface with adhesive tape on its back, holding a cable bundle with a cable tie passed through it. What Is a Fused Terminal Block? Types and Selection Criteria — A fused terminal block is a DIN rail terminal block that protects its circuit with a glass fuse fitted in its housing and isolates the line when the fuse is removed. What Is a Panel Earth Terminal Block? Types and Selection Criteria — A panel earth terminal block is a multi-way terminal that gathers a panel's protective (PE) conductors at a common point on a drilled bar and connects them to the main protective conductor. What Is PVC-Coated Galvanized Spiral Conduit with Pull Wire? Types and Selection — PVC-coated galvanized spiral conduit with pull wire is a cable protection conduit with a ready cable-pulling wire inside a PVC-sheathed, flexible galvanized steel body. What Is a DIN Rail Socket? Types and Selection Criteria — A DIN rail socket is a modular socket that clips onto the 35 mm DIN rail inside a panel, like a circuit breaker, to supply devices during maintenance. What Is a Cable Gland O-Ring? Sizes and Selection Criteria — A cable gland O-ring is a round-section ring seal fitted on the threaded neck of a cable gland to close the gap between the body and the enclosure wall. What Is an Earthing Terminal? Types and Selection Criteria — An earthing terminal is a non-insulated connection end crimped onto a protective conductor to connect it to the earthing screw or stud on an equipment housing. What Is a Cable Carrying Organizer? Types and Selection Criteria — A cable carrying organizer is a handled frame without a rotating drum, on which an extension cable is wound by hand so it can be carried and stored without tangling. What Is a Galvanized Spiral Conduit? Types and Selection Criteria — A galvanized spiral conduit is an unsheathed flexible metal conduit made by helically winding galvanized steel strip that protects cables against crushing and impact. What Is an Axial Cooling Fan? Types and Selection Criteria — An axial cooling fan is a compact fan that moves air along its shaft axis to remove heat from enclosed spaces such as panels, drives and power supplies. What Is a DIN Rail? Panel Mounting Rail Types and Selection Criteria — A DIN rail (panel mounting rail) is a carrier profile onto which modular devices such as circuit breakers, residual current devices, contactors and terminal blocks snap inside a panel. What Is a Long-Thread Cable Gland? Sizes and Selection Criteria — A long-thread sealed cable gland is a plastic cable gland whose entry thread is longer than a standard gland's, sealing the cable with its insert in thick-walled housings. What Is an Automatic Cable Reel? Types and Selection Criteria — An automatic cable reel is a fixed-mounted power transfer reel, supplied with its cable, that pays out the cable as it is pulled and winds it back by its own mechanism when released. What Is a CEE Adapter? Types and Selection Criteria — A CEE adapter is a transition piece, plug at one end and socket at the other, that connects a plug of a different current, contact count or type to a CEE (IEC 60309) socket. What Is a Junction Box? Types and Selection Criteria — A junction box is a covered connection box that encloses conductor joints and line branch points in an electrical installation.
