How are receiving headers classified

　　At present, there are two main categories of connectors on the market from the packaging method: Pressure model and glue-filling type, from the two packaging processes, the pressure model equipment investment is larger, the price of the rubber cake is more expensive, so the overall price is more expensive, of course, its anti-interference ability is strong, the receiving Angle is large (circular 360 degree reception), the investment in glue-filling equipment is small, and now most of the domestic factories are glue-filling products, the advantage is cheap, The disadvantage is that the ability to resist light interference is poor, and the reception is small (270 degree reception).

　　The pressure model is divided into two types of plastic sealing and iron shell, which mainly depends on customer needs. The iron shell (dual external shielding) has a certain shielding effect against light and power interference, and the receiving performance is relatively stable; Of course, if the product design is OK, the receiving distance with plastic sealing under the same conditions is slightly farther.

　　Glue filling type is also divided into two types of plastic sealing and iron shell, in the choice of receiving head, whether to take iron shell, which should be determined according to the design, in general, the use of plastic sealing in toy products, used in household appliances with iron shell more. Of course, there will be some differences in the price with or without the iron shell.
