Cable choice.
An important element of assessment is the length of the cable. Each meter of the cable causes a voltage drop proportional to the value of the current that runs through it, if cosf = 1 we have: V = IxR.
V = voltage drop, I = current, R = resistance of the cable. In the case of inductive loads (solenoid valves, motors, etc.) or with variable currents, the higher current peak must be considered to avoid even temporary loss of power, which could hinder the proper functioning of the equipment. The longer is the cable, the greater the voltage drop, the IEC allows maximum values drop from 3% to 5% of rated voltage. Greater values are admitted only for the current peaks (e.g.: engines starting), if they do not create functioning problems. To minimize the voltage drop the cable section should be increased. Here are some tables that can help to easily calculate the minimum theoretical cable section. See tables 3 and 4 on the page http://www.shield.net/files/catalogue/support/2.2.pdf
For example, an average continuous current 1 A with section 0,34 mm2 and cable length 10 m generates a voltage drop of 1,3 V, which is approximately 5% of 24 V.

The Spider Box is a modular solution: simple connections or complex bonded junctions according to client’s design can be wired and over-moulded with an efficient cost/quality rate. #Assembly with shielded or unshielded #cables. Up to 20 cables connections with multiple wires can be linked together. Electronics: standard circuit or built-in custom electronic circuits design are available. Hybrid versions with M8 and M12 connectors + direct cable junctions are also available. It’s the solution to reduce the design and cables assembling time in your project.
Some of the main advantages:
– Even a not skilled worker can assemble the machinery electrical parts.
– Easy maintenance for the machinery electrical parts.
– It reduces the stock part numbers.
– Possibility to built-in sophisticated electronic components as well.
