According to different structure series and plug connector models, single, multiple, and thin wire cross-sections can be connected, with or without core wire terminal sleeves, with an area of 0. It is the only new-generation connector in the world that has passed the North American NEMA 250-1991 Typ 4x specification. The reason is that the RockStar housing only has inteal threads, so that the usual threaded connections are not needed when the wires pass.
Weidmüller heavy-duty connectors are carefully packed in small plastic bags in strict accordance with the China Female Header order quantity, which reduces storage costs, and there is no longer a supply of ultra-large packaging units. In other words: they must not fail in operation. IP69k type enclosure is also available in XXL type. However, this alone is not unusual, because the heavy-duty connector technology has been recognized as a mature technology in the market.
Therefore, Weidmüller has conducted research and analysis on heavy-duty connectors. Since all the bent irons and bolts of the interlocking system on the RockStar standard housing are also made of stainless steel, there is no need for a housing originally designed for corrosive environments.
Two of the advantages of the connector are unique features that RockStar shows: First, this connector is the only one in the world that has passed the North American regulation NEMA 250-1991Typ 4x verification. The advantages are: the connector equipped with this contact system has a large contact surface, small heat generation, small size and large design current. The advantage of this is that the customer does not need to record many order numbers and warehouse positions, but only one order number and one warehouse position
Compatible, so you need to use level conversion circuit to connect with TTL circuit. 2. 5. The inteational standard of RS-485 does not stipulate the standard of RS485 interface connector, so you can use terminal blocks or DB-9, DB-25 connectors. Because the RS-485 interface has good anti-noise interference, long transmission distance and multi-station capability, the above advantages make it the preferred serial interface. What are the characteristics of RS-485 compared to RS-232-C interface? Answer: Since the RS-232 interface standard appeared earlier, it is inevitable that there are shortcomings, mainly as follows: (1) The signal level of the interface is high, which is easy to damage the chip of the interface circuit, and because the level is different from TTL level.2Kbps.
The RS-485 interface allows the connection of up to 128 transceivers on the bus, that is, the RS-485 has multiple Machine communication capability, so that users can use a single RS-485 interface to easily establish a device network. (2) The transmission rate is low.5PF/M, and the terminal load resistance is 100 ohms. The Boss RS-485 interface is a de facto industry standard. This length data is mainly limited by the influence of signal distortion and noise.
When the data signal rate drops below 90Kbit/S, assuming the maximum allowable signal loss is 6dBV, the cable length is limited to 1200M. Now due to the new UART chip 16C550, the baud rate reaches 115. The condition is that RS-422 must be able to support multi-machine communication.NO.51mm), the bypass capacitance between the lines is 52. Among them, about 99% of users work in the range of 10-20% symbol distortion, so the maximum distance in actual use will be far more than 50 feet.
Can the Waterproof Connectors Manufacturers be shorted as RS-485 A, and the Z-B of RS-422 can be shorted as RS-485 B? Answer: Not necessarily. The highest data transmission rate of RS-485 is 10Mbps. The main difference is: RS-422 has 4 signal lines: two sending (Y, Z) and two receiving (A, B). RS-485 has 2 signal lines: A and B for both sending and receiving
