【It is a semiconductor device which makes silicon material and controls current.】It is applied to effect clipping circuit etc. It is one of the fundamental components of semiconductor. In digital circuit, transistor is basically used as amplifier, also, it can be used as a non-contact switch electronic switch.The transistor was once designed for high speed switching applications and it provides useful current gain over a wide range of collector current, low saturation voltage.

【There are NPN transistor output type and PNP transistor output type.】NPN transistor output type is used for connecting the load between + (plus) of power supply and sensor output in the circuit to be connected. PNP transistor output type is used to connect a load between the sensor output and the power supply - (minus) in the circuit to be connected.The input device to be connected is minus It becomes common type.

【This transistor is a stapler in many scenes with its own actuators. 】A lot of about 600 pieces, A1015, C1815, S8050, S8550, and S8512, which also can not contain the relatively high frequency of the transistor it is full of sensation. We have 15 different models to choose from! Feel free to use it to meet your basic needs.

【The packaging is elaborate and beautiful, packed in one compact plastic storage box.】It is holding various bipolar triode properly.Because it is partitioned, no worry that so many through-hole transistors are scattering apart so much, please use with confidence.

【Somewhere in the wiring of the sensor output line is widely used in Europe from the safety point of view】because the load does not operate even if it is short-circuited to 0 V. The input specifications and circuits of the connected equipment Please select according to the safety requirements of.
