RJ45 is used to connect Ethernet port on your computer. There are two configuration: straight and cross. Straight RJ45 cables should be used to connect between computer and device such as switch or hub, and cross RJ45 cables should be used in computer-to-computer connection. Some hub or switch has the capability to detect the cable type and accept both straight […]

This pin diagram will be useful when viewing these connectors. Sometimes you hold a soldering iron to the back of the connector, and you don’t remember the numbering of the pin. Here is the pin diagram for your reference: The number of each pins are actually stamped on both sides of any D-type connector. Unfortunately, since they are only moldings, […]

Silicon pezoresitive-bridge pressure transducer (SPPT) is very popular in medical, industrial, environmental, and automotive pressure sensor application. The general architecture of SPPT uses a thin micromachined silicon diaphragm incorporates a implanted piezoresitive Wheatson-bridge strain-gauge. The transducer design allows only a small diaphragm deflection sin it has limited elasticity, and this produces only a very small output signal, only about 1% […]

Photovoltaic transducers has been widely used in medical, consumer, scientific instrumentation, and industrial applications. Photovoltaic sensors is a solid-state devices and available for wide range of wavelength response, cover from infrared, visible, and ultraviolet spectrum. This characteristic make this type of transducer applicable in diverse jobs such as colorimetry, chemical spectral analysis, non-contact thermometry, non-invasive blood-gas monitoring, and flame detection.
