Shanghai Jingpu Electromechanical GMX60 multi turn encoder has passed the CE certification of TUV Rheinland in Germany-Intelligent Manufacturing Network

On February 15th, Shanghai Jingpu Electromechanical's GMX60 series passed the CE certification of TUV Rheinland in Germany (a large product safety and quality certification organization in Germany, a German government inspection agency with a 145 year reputation in Germany and Europe as the current provider of testing technology and certification services)

TUV conducts rigorous testing on its certified products to ensure higher safety. The sample selected by Shanghai Jingpu Electromechanical is the SSI multi circle value encoder GMX60 R12/12E10 SGB with a wide range of applications, simple operation, and applicability to various PLCs, as well as the matching control digital instrument GP1312.

There are a total of 6 tests in TUV's testing experiments, including the important EMC basic standard series (IEC61000 series)

Electrostatic discharge immunity test

according toEMCElectromagnetic compatibility standards
Experimental purpose: To simulate the discharge of operators or objects in contact with the equipment and the discharge of people or objects to adjacent objects, in order to examine the ability of the tested equipment to resist electrostatic discharge interference. The former is directly coupled through a conductor and belongs to direct discharge. The latter is through spatial radiation coupling and belongs to indirect radiation effects.
Automated site: corresponding to the electrostatic discharge associated with a large amount of dust particles on site.

Radio frequency electromagnetic field radiation immunity test

Implementation of the experiment

After 80% amplitude modulation of the signal with a 1kHz sine wave, sweep frequency measurement is carried out in the frequency range of 80-1000MHz, with a sweep step size of 1% of the previous frequency. This part is controlled by computer and software.
The scanning dwell time at each frequency point should not be shorter than the time required for the operation and response of the tested equipment, generally set to one second. If there are special requirements for the product, the dwell time can be extended.
The test equipment should be tested under the horizontal and vertical polarization of the transmitting antenna.
Automated site: Corresponding to the electromagnetic wave emission interference of various metals in different frequency bands, including metal wire ends and sharp angle electromagnetic wave emission interference.

Voltage sag, short interruption, and voltage variation immunity test

According to EMC electromagnetic compatibility standards

Objective of the test

Simulate the power grid caused by faults in the power supply grid or substation equipment, sudden large changes in load, or continuous changes in load
Test the immunity of the tested equipment to transient voltage drops and short-term interruptions.
The EUT test level and duration are selected according to standard or product technical requirements, and after combination, arranged in order of delivery and tested sequentially. The number of tests for each combination state is specified as 3 seconds, and the interval between two tests is 10 seconds
The sudden change in power supply voltage during the experiment occurs at the zero crossing point of the voltage and at the critical phase specified in the product technical conditions. For three-phase power supply equipment, tests are generally conducted phase by phase.

According to our promise of an effective transmission distance of 100 meters for our product, TUV testing agency is required to conduct a 100 meter cable test on the sample during testing, which requires higher output signal requirements for the encoder. This test includes testing the electromagnetic field radiation interference of the product in the frequency range of 80-1000MHz and 1.4-2.7GHz. Whether the signal is stable and the data is accurate, the digital display instrument is clear at a glance, which can be seen on the spot in the laboratory. If any indicator is not qualified, the experiment will be closed on the spot.

The GMX60 series products are a multi turn encoder series developed in 2018 by professional engineers with advanced research and development technology, based on the original GAX60 series. The preferred products in this series are the GMX60 R12/12E10 SGB and GMX60 R12/12E10 RMLB. The former is characterized by SSI signal remote transmission stability technology, while the latter is characterized by intelligent Easypro technology with four signal outputs: 4-20mA, RS485, Modbus, speed, etc.

The GMX60 series is an upgraded version of the GAX60 series. Whether it is the processing of internal components (using high-quality raw materials, working at high and low temperatures, resistant to vibration and impact) or the higher requirements for processing technology (waterproof type, sealing), it is superior to the GAX60 series. Only when the product itself requires high specifications can it provide higher quality multi turn encoders to serve users.

The high requirements of the GMX60 series can be seen from the testing instruments, as shown in the following picture:

Why does GEMPLE need to obtain TUV certification?

Making products requires standards so that customers can use them with confidence. Standards need to be verified, and verification must be fair and transparent. T ü V Rheinland Group is an independent, impartial, and professional organization. We choose TUV for fairness, safety, and higher transparency, as well as a high level of trust and confidence in our product performance and quality.

We strictly follow the standard requirements to increase users' trust in our products, achieve reliable technology, reliable quality, high quality and service, and provide high-performance cost-effectiveness. Only by doing our products well can users truly reduce costs in the era of economic downturn.

Does the price of the product increase after obtaining German TUV certification?

With the approval of CE certification, customers can use this series of products with more confidence. In order to allow more customers to experience this series of products, Shanghai Jingpu Electromechanical Co., Ltd. has decided to test two products:
