It is very common in blogs and websites to incorrectly name a specific connector only by the name of the manufacturer. To minimize confusion, it is best to describe a connector using: the manufacturer's name, exact connector series, and optionally the pitch, such as "JST-XH" or "JST-XH-2.50mm" or "2.50mm JST XH-series" or other variations.
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
A freehub is a type of bicycle hub that incorporates a ratcheting mechanism. A set of sprockets (called a " cassette ") is mounted onto a splined shaft of the freehub to engage the chain . The ratcheting mechanism is a part of the hub, in contrast to a freewheel , an older technology, which contains both the sprockets and a ratcheting mechanism ...
DK Bicycles introduced the Dual Drive hub back in the early 2000s which is a BMX Left/Right drive flip flop hub with the smaller sized metric (30 mm x 1 mm) BMX threads for 13T-15T freewheels, but also includes two threaded adapters, one left and one right, threaded inside to match the smaller metric threads and threaded on the outside with ...
Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
This connector is present on newer heavy duty commercial trucks and trailers following the ISO standard and is intended to replace the combination of connectors according to standards ISO 1185 and ISO 3731. The 15-pin connector is not designed to replace the ISO 7638 connector. [18] #
The power connector on the 3½-inch floppy drive, informally known as "the Berg connector", is 2.50 mm pitch (distance from center to center of pins). The power cable from the ATX power supply consists of 20 AWG wire to a 4-pin female connector. [ 1 ]
The ignition coils for these can be combined into a single casing (a coil pack) and located away from the spark plugs; however it is increasingly common for coil-on-plug systems to be used, whereby the individual ignition coils are small units attached directly to the top of each spark plug. An advantage of coil-on-plug systems is that in the ...
