    FAQ

    Q: I am a whole seller, I want to buy your parking sensor, do you have it for aftermarket?

    +
    A: Yes, Coligen make parking sensor for both OE& aftermarket, 90% is for OE and 10% for aftermarket, both with OE quality.

    Q: My customers want a cost down solution, can you offer us a good solution with cheap price?

    +
    A: Yes, Coligen have NON-ECU parking sensor system, which supports maximum 8 parking sensors( FPAS4+RPAS4).

    Q: Can your parking sensor be used for both PV&CV application?

    +
    A: Yes, PV(12V)& CV(24V), we will use adopt the right power management IC. And we will use the right bracket for different application. But need customer to provide the bumper data so that it can achieve the best performance.

    Q: If your parking sensor can be used for APA application?

    +
    A: Yes, we have the new generation AK2 sensor. Which have longer detection range and better performance, especially for APA and L2~L3 application.

    Q: My customer always request urgent delivery, how long it will take upon my order and down payment?

    +
    A: Coligen have 10 automatic production lines with huge capacity, normally it will take around 25~30 days. But there is some lead time materials which will take longer time, please send us your forecast or place order in advance.
