Sensor Cable - Accessories GM 207-7 Application Field and Working Principle

GM 207-7 is an industrial accessory for use with various sensors such as proximity sensors and solid state switches. It is a piece of cable designed to provide an electrical connection from a sensor to a digital device or switch. The GM 207-7 is designed to carry up to 250 mA and a voltage up to 60V DC. It is UL approved and under UL 20276.

Common application fields of the GM 207-7 include: robotics, machine vision, automated control systems, and other automated devices. The cable is featured with a white plastic core, with integral test lead wires. It can also be used for electrical wiring requirements in hazardous, explosive, or moist environments, as its rubber sheathing is resistant to long exposure to sunlight, ozone, chemical agents and elevated temperatures.

The GM 207-7 has three conductors, usually marked by a red, blue, and yellow color. Red is ground, while blue and yellow are used as positive and negative conductors. The conductors have stranded, silver-plated copper wires to reduce electrical resistance and provide better connection. The ground conductor is easily identifiable, and the polarity of the other conductors is clearly labeled.

The GM 207-7 has a UL 94V-2 flame retardant rating, allowing it to be used in applications where the cable might be exposed to high heat or flame. It is also rated for exposure to water and oil, making it suitable for a variety of applications. The GM 207-7 can also be used in vibration-prone environments, as its construction includes a reinforced jacket for added flexibility and strain relief.

When using the GM 207-7, it is important to be aware of the working principles. In operation, a current is run through the red ground cable, which is then transferred to the other two wires—blue and yellow—which are both positive and negative conductors. The GM 207-7 also contains an impedance matched current-limiting system. This ensures that the cable can carry up to 250 mA of current without overheating.

In conclusion, GM 207-7 is a practical and reliable solution for connecting sensors to digital devices or switching applications. Its quality construction can withstand harsh conditions, and the flame-retardant jacket provides protection from damaging heat and flame. Furthermore, the GM 207-7 is UL approved, and its impedance-matched current-limiting system enables it to carry up to 250 mA of current without overheating. Therefore, it is an ideal cable for industrial automation applications.
