How to choose the right RAST connector?

RAST Connectors are common parts in almost any electronic project. It is very important to understand the selection process of connectors and the precautions during the selection process. You definitely don’t want to find that you need to add content and adjust the project to adapt to this change when the project is nearing the end, which will increase the time and expense costs. In order to avoid this situation, the process of selecting the right RAST connector must be careful.

Introduction

With the rise of household appliances, as early as the 1970s, in order to reduce the work intensity of first-line workers and reduce product damage caused by connector misinsertion rates, the overall processing cost was reduced. So, Europe began to gradually introduce a new product, that is RAST connector. At present, RAST connector technology/concept is widely used in traditional superior industries such as automobiles, air conditioning heating and ventilation (HVAC) and household appliances.

Characteristics

RAST connectors are used for a variety of appliance components, such as pressure sensors, relays, pumps and rotary switches in addition, RAST products are specified for connections to printed circuit boards in motor controls and switches. Because the connectors have a standard configuration, OEMs and component suppliers can use standardized designs and have less need for custom-manufactured components.

The selection processes

The mechanical engineer confirms the mechanical characteristics of the connector (temperature, humidity, and corrosion resistance) 2. The ability of the hardware engineer to calculate the overcurrent of the connector 3. Confirm whether multiple connectors are foolproof, preventing different connectors from choosing the same model 4. The hardware confirms that the signal and the power supply go from different connectors. Will there be a situation where the chip inside a suspended module of the connector is damaged? 5. Determine the order of the male pin arrangement 6. Determine the arrangement order of the female connector after software conversion 7 After the conversion is completed, carefully check whether the circuit board and the wiring harness are connected correctly.

Conclusion

Comprehensive consideration: In the process of selecting connectors, various factors are not independent and often interact. Therefore, we must consider comprehensively in the process of RAST connector selection, choose the most suitable connector, the choice is different. This stage will affect the product to varying degrees.
