Product Description of RPM Sensor 0513-5210

The RPM Sensor 0513-5210 Turbo Charger Sensor delivers accurate rotational speed measurement in demanding engine environments. It fits directly into a threaded M12 × 1.25 mm mounting port, so installation stays simple and secure. Because turbochargers spin at extremely high speed, even small errors in detection can lead to severe mechanical damage. Therefore, this sensor continuously monitors turbine rotation and sends clear signals to the ECU, controller, or monitoring panel.

Moreover, the sensor detects 1 to 31 vanes and generates one impulse per vane count, which allows precise RPM calculation across many turbo models. Engineers can quickly connect it to digital control systems since it provides TTL/CMOS output. At the same time, the 0.5–4.5 V analog signal supports gauges, PLC modules, and protection relays. As a result, the device suits generator engines, marine engines, heavy trucks, and industrial turbocharged equipment.

The rugged IP67 protection rating shields internal electronics from dust, oil mist, and water splash. Consequently, the unit performs reliably inside engine rooms and outdoor installations.

Built for Harsh Operating Conditions

The 0513-5210 sensor operates from 9–30 V DC, so it works with 12 V and 24 V vehicle electrical systems without additional converters. In addition, the -40°C to +85°C operating range ensures dependable performance in cold starts and high-temperature engine compartments. The long 148 mm body length positions the sensing tip at the correct turbine clearance, improving signal stability and reducing false readings.

Because the housing uses durable industrial materials, vibration and continuous operation do not affect measurement accuracy. Furthermore, the sealed connector design minimizes wiring faults and maintenance time. Operators can therefore rely on consistent turbine speed feedback, enabling overspeed protection, preventive maintenance, and safer engine operation. Manufacturers in China produce this sensor using standardized industrial processes, which helps maintain stable quality while keeping costs competitive.
