Visible light receiver
Visible light receiver The amplitude-modulated optical signal receiver uses a phototransistor Q1 installed in a parabolic mirror (in order to expand the range). Any NPN phototransistor can be used. The output of the follower Q2 driver amplifier Q3.Q3 is sent to the volume control resistor R7 and the audio amplifier U1, and the 9-12V power supply is applied to the receiver.
The Through-Wall Terminal Block adopts screw connection wire technology, the insulation material is PA66, and the connector adopts high-quality high conductivity metal material.Through wall type Terminal Blocks can be installed side by side on the panel with thickness of 1mm to 10 mm, which can automatically compensate and adjust the distance of panel thickness to form a terminal strip with any number of poles, and can be used to increase air gap and creepage distance. Without any tools, the through wall terminal block can be firmly installed in the rectangular reserved hole on the panel, which is extremely convenient for installation.
Through-wall terminal block, structure design feature is easy connection and high contact strengths. These connectors are available in all types of wires with the size from 0.5mm2to 95mm2, and designed in accordance with IEC60947,UL1059,UL486E and CSAC22.2No.158.
