Multiple Conductor cables have a wide range of applications, and one type of cable is the 89901 E4X500 type. These cables are often used in instrumentation, telecom, and power control applications. This article will discuss its application field and the working principle.

Application Field

The 89901 E4X500 cables are generally used in applications that require flexibility and protection of the conductors from external influences such as temperature, dynamic movement, and physical forces. These cables are made up of 4 conductors with each conductor having a cross-sectional area of 0.50mm2. The cables provide electrical resistance up to 16 Ohms/km. In addition, these cables offer a low transfer impedance, good flexibility, and are UL and CSA listed.

The 89901 E4X500 cables are used in a wide variety of applications including instrumentation, telecom, and power control. These cables are especially suited for applications where multiple twisted pair are needed and where there is a need of noise protection.

In instrumentation applications, these cables are commonly used for signal transmission and control in process plant instrumentation. In telecom applications, these cables are used for telephone circuits and intercoms. In power control applications, these cables are used for remote control systems and energy management systems.

Working Principle

The 89901 E4X500 cables are made up of four twisted pairs of stranded conductors in a sheath. The conductors are composed of finely stranded tinned copper and are insulated with a polyester-themed or crinkle paper covering. The covering helps to reduce the effects of vibration, noise, and other environmental influences.

These cables also have an outer jacket for additional protection. The outer jacket is made of polyethylene or PVC and provides protection from physical damage, moisture, and temperature variations. This outer jacket also helps to reduce the noise from the cable by dampening the electrical signals.

The four twisted pairs of conductors provide good shielding from electrical noise interference. The shielding is provided by a layer of aluminum foil placed between the conductors and ground. The aluminum foil also acts as a shield against disturbances generated by other cables.

The 89901 E4X500 cables also provide good contact resistance. This is due to the surface finish of the connectors. The insulation on the conductors is also designed to provide good low-impedance and current-carrying characteristics.

In addition, these cables have a high crush resistance, high temperature resistance, and good mechanical properties. This makes them ideal for use in harsh environments, where cables must withstand vibration, temperature fluctuations, and heavy usage.

Conclusion

The 89901 E4X500 cables are excellent for a wide range of applications where flexibility and protection from external influences are needed. These cables provide excellent electrical properties, excellent noise shielding, and good contact resistance. The outer jacket and shielding also provide protection from physical damage and environmental influences. This makes them an ideal choice for applications where multiple twisted pairs are required and where noise protection is necessary.
