Product Description
Angle sensor measures the absolute Angle position of the sensor shaft by sensing the parallel magnetic field strength of the permanent magnet installed at the end of the sensor shaft. The measurement Angle range is 0~359 °, and the maximum full range measurement error is ± 0.1 °. The digital output mode avoids the output signal error introduced by the deviation and temperature drift of the analog output circuit, which is guaranteed
The original measurement accuracy of the sensor. The DC power supply voltage is 6V ~28V, with reverse protection.
Using-is measurement to make the durability of the sensor depends on the sensor bearing. This type of Angle sensor uses high-quality bearings to ensure the long-term and reliable use of the sensor. This feature makes it an alternative contact angle sensor such as conductive
Excellent product for plastic.
This product has a variety of shell models to choose, to meet the different connection, installation and outlet mode.

Measurement performance
The LOGJD485B-type Angle sensor measurement Angle range is from 0 to 359.9 °, and the full range measurement error does not exceed ± 0.2 °. The maximum repetition error was ± 0.1 °. The digital output mode avoids the error introduced by the deviation and temperature drift of the output analog circuit, and guarantees the original measurement accuracy of the sensor. The product adopts effective temperature drift suppression measures to make it in the effective operating temperature range
Inside (-30~ + 85ºC), the maximum temperature drift does not exceed ± 0.003 ° / ºC.
Signal output frequency
The signal acquisition and processing time of LOGJD485B angle sensor is typical of 3ms, and the interval is the signal acquisition and processing time plus the data transmission time. The data transmission time is 50 / port rate, which is the time required to send 5 bytes in the current serial port speed (the port rate). Default port rate 9600 hours, send time is 50 / 9600, about 5.2 ms,
Therefore, the sensor continuously sends the data at an interval of 8.2 ms.
When the query mode is communicated, the transmission interval depends on the query frequency.
There are two modes of communication between the sensor and the data receiver: the data to the sensor, that is, the sensor collects and processes the data, but does not send the data continuously and sends the data from the data receiver to the sensor. By default, the sensor uses a continuous transmission mode. According to the needs of customers can be output according to the query mode, query instructions can be according to the actual situation of the customer
Situation, flexible setting.
RS485 The output port rate is 9600bp s by default, and different port rates can be set according to customer requirements.
working power supply
The LOGJD485B-angle sensor has a wide operating voltage range: 6V~28V. When the power line is connected or disconnected, the spike pulse voltage of 25~60V can be generated, which can easily cause damage to the sensor circuit system. The protection measures of the power input end of the LOGJD485B-type Angle sensor can effectively suppress the interference of this kind of spike pulse and make the sensor circuit system safe and reliable
work. The power supply system has a reverse protection diode, with the reverse protection voltage up to 40V. communicating protocol1. String way Data composition | start bit | data bit | stop bit | unit |

2. Data-frame structure The data frame sent by the LOGJD 485B angle sensor consists of frame head, data and calibration. The frame header and calibration use 16Compound code, data with compressed BCD code. Data verification is different or calibration. BCD code (Binary-Coded Decimal) is also known as a two-in decimal number or two-decimal code. Use 4-bit binary to represent the 10 digits in 1 decimal digit. Is a binary form of digital encoding, with a binary-coded decimal code. The BCD encoding form uses four bits to store a decimal digital number, making it binary and decimal The transition between can on quickly.Compressed BCD, the code is with 1 byte of high 4 bits and low 4 bits respectively for 2 bits decimal digital.The frame structure is as follows: Frame head (1 Byte) | data field (3 Byte) | verification (1 Byte) |

Note: The highest bit of a and BYTE2 is the symbolic bit: 0 is positive and 1 is negative. For the standard measurements, the data are all positive.B, check mode: data field 3 byte different or check value, hexadecimal code representation.
