What Tests Need to Go Through Before Delivering a Slip Ring Unit

ByTune Electronics Co.,Ltd | Updated: Aug 07, 2017

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary part to a rotating part. A slip ring can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power, electrical signal and data.


Generally speaking, all slip rings must go through basic electrical performance test which including appearance check, lifespan check, static contact resistance, dynamic contact resistance, insulation resistance, dielectric strength and friction torque tests. These final test data will reflect the quality of materials and a good or bad production process. For common security and industrial applications which just need transfer power &general electrical signals under normal working conditions, such as packaging/wrapping machines, bottling and filling equipments, go through basic electrical performance test is enough to evaluate if a slip ring is qualified.


Testing of real world environments and worst-case scenarios in slip ring applications is just one way to ensure they are ready to endure the unforeseen and to keep product downtime to a minimum. The value of shock and vibration testing, just like the value of any environmental testing, is to verify that a product can function properly for the purpose it was designed. A slip ring assembly can have potentially hundreds of individual parts, which are assembled together to create a working product. Each of these parts has a purpose and without even the simplest part, the whole assembly can fail. This is why the best way to ensure the assembly will work is through product testing.


To ensure the quality of each product, ByTune brings in a full set of testing equipments to test each slip ring including Signal transmitting test, Life test, Vibration test, Low-high temperature test, Large current test, Vacuum test, Two dimensional measuring, Contact resistance test etc.
