Non Contact Angle Sensor, CAN/TTL, 0~30°/0~360°

Good Sensor Online Store offers high-precision angle sensors. The SUCH-520A angle sensor integrates MEMS technology, features low power consumption, and employs magnetic induction technology with non-contact measurement of the shaft. Through MCU processing, it enables programmable intelligent control with multiple segments of different slope settings, achieving output of the sensor's absolute angle position within the 0–360° range. The accuracy is 0.05°, and the signal output options include: RS232, TTL, RS485, CAN, 0-5V, 0.5-4.5V, 0-10V, 4-20mA, and 0-20mA.

Feature

• Non-contact angle sensors operate based on magnetic induction or optical principles, enabling angle detection without physical contact. This eliminates friction and wear, ensuring long-term measurement stability and accuracy.
• Angle sensors feature vibration resistance, dust resistance, and high-temperature tolerance, enabling stable operation in complex environments such as automotive engine compartments, industrial machinery, or outdoor equipment, with reliability far surpassing traditional potentiometers.
• Thanks to their non-contact design, contactless angle sensors can achieve a lifespan of millions of cycles with minimal maintenance, making them ideal for applications such as automotive electronic control systems, robot joint detection, and industrial automation.

Angle Sensor Filter Circuit

The angle sensor is processed by an MCU program and features an integrated design with a voltage transmitter. The measurement angle range can be set within the 0–360° range according to user requirements. It outputs industrial standard 4–20 mA and 0–20 mA current signals. It is particularly suitable for angle position detection and applications requiring connection to a programmable logic controller (PLC).

The MK520A non-contact angle sensor's signal output stage includes reverse protection diodes with a reverse breakdown voltage of 40V (default), which can be increased to 100V upon customer request. This effectively prevents damage to the signal output stage caused by accidental connection of the signal line to the power supply (VCC) positive terminal. In industrial environments, the sensor's signal output stage may be exposed to higher transient voltages. To better protect the sensor, measures such as transient voltage suppression (TVS) can be added. During use, occasional overcurrent damage to the sensor may occur due to improper wiring or wire wear and leakage. Installing a self-resetting fuse inside the sensor maximizes protection against damage from sudden high currents.

When the load resistance Vcc=12V is 250Ω, the noise peak-to-peak value reaches 20mV without filtering. By using the filtering circuit and parameters shown in the figure, the signal noise peak-to-peak value is reduced to a maximum of 2mV. The larger the values of the filtering resistors and capacitors, the better the filtering effect, but the signal response speed decreases. Select appropriate filtering circuit parameters based on actual application conditions.
