CRIMPING PROCESS ( RJ 45 Connector )

A crimping tool is a tool designed to crimp or connect a connector to the end of a cable. For example, network cables and phone cables are created using a crimping tool to connect the RJ-45 and RJ-11 connectors to the end of the cable. In the below example picture, this crimper is capable of crimping a RJ-11 (6-Pin) and RJ-45 (8-Pin) connectors and also includes a wire cutter near the handles that can be used to cut phone or CAT5 cable. To use this crimping tool, each wire is first placed into the connector. Once all the wires are in the jack, the connectors with wires are placed into the crimping tool, and the handles are squeezed together. Crimping makes the plastic connector puncture and hold each of the wires, which prevents the wires from falling out and for data to be transmitted from the connector to each of the wires.

TIA/EIA Twisted Pair Categories

CAT3:

ØContains four wire pairs

ØProvides 10 Mbps throughput and 16 MHz bandwidth

ØLimits segment length to 100 m (330 ft)

ØWidely used in VoIP networks

Variable Power Supply ( by PCB layout for Single layer Design )

1.2 ~ 24V @1A, Regulated DC Power Supply Using LM317

This simple low cost

DC power supply circuit provide very stable DC voltage (adjustable) from 1.2V to 24V. The use of LM317T regulator IC simplifies the circuit by reducing the number of required external components. The total parts count is less than 10

The maximum output current is 1A

You may use it to power your electronic projects that require stable DC supply.

FEATURES:

OUTPUT VOLTAGE RANGE: 1.2 TO 24V

0.1% LINE AND LOAD REGULATION

Equation for calculation of output voltage:

Vout =1.25 x ( 1+ VR1/(R3+R4) )

where R3 =470Ω, R4= 56Ω & VR1 adjustable from 0 ~ 10KΩ

Eg.:

VR1=0Ω when it's fully counter clockwise,

Output voltage = 1.25x(1+0/(470+56) = 1.25V

VR1=10K Ω when it's fully clockwise,

Output voltage = 1.25x(1+10,000/(470+56) = 1.25x(1+19) = 25V

PARTS LIST:

IC1: LM317T 3-terminal adjustable linear voltage regulator IC

LED1 3mm or 5mm LED (Any Colour)

D1, D2 1N540x (X=2,..., 8) rectifier diodes   ( if possible purchase 1N5402)

Resistor: (1/4W or 1/6W)

R3 470Ω

R4 56Ω

R5 3.3K

Potentiometer: (B) 10K (linear taper) (output voltage adjustment)

Capacitors:

C1 either 2200 uF, 63V (min 35 V)

C2 100 uF 25V (min) Electrolytic capacitor  

Miscellaneous items:

2 contact screw terminal block x 1 pc.

3 contact screw terminal block x 1 pc.

TO220 Heat Sink (for IC1) x 1 pc.

Single Layer PCB (min size 13 x 7 cm )

Power transformer required: (HT24E15) Primary: ~230V, Secondary: 24V024V @1A
