RD-H indirect speed sensor

The RD-H AC220V speed sensor is a new type of speed sensor that uses a magnetic sensitive resistor as the sensing element. The core component uses a magnetic sensitive resistor as the detection element, and then undergoes a brand new signal processing circuit to reduce noise and improve functionality. Compared with the output waveforms of other types of gear speed sensors, the measured speed has small errors and good consistency in linear characteristics The sensing object is a magnetic material or a magnetic conductive material, such as magnetic steel, iron, and electrical steel. When a magnetic or magnetic material with protrusions (or indentations) on the object being measured rotates, the sensor outputs a pulse signal related to the rotation frequency to achieve the purpose of speed measurement or displacement detection.

The speed sensor RD-H AC220V has the following characteristics:

High sensitivity, high reliability, long lifespan, long triggering distance

Signal triggered by iron (soft) magnetic material

Capable of achieving long-distance transportation with strong resistance to electromagnetic forces

Good impact resistance and earthquake resistance

Parameter Description

Note: 1. Gear size parameters: gear outer diameter: 99.3mm; number of teeth: 60; Modulus: 1.57 (The above dimensions are just one example, modulus can range from 0.5 to 2.)

2. When installing the sensor, make the connection between the red LED at the tail and the root of the lead wire perpendicular to the gear plane.

3. The sensor leads are: brown is the power cord; Black is the ground wire; Blue represents the signal output line.

Due to its convenient installation and good universality, it has been widely used in various domains. Especially in low-speed or ultra-low speed non-contact detection, there are characteristics that other sensors cannot achieve

50-5000Hz. (, detection distance is only 0.5mm; proximity switch cannot detect small mold teeth); In non-contact detection at medium and high speeds, it can directly replace Hall switches.

Precautions for using magnetic switches
(1) Voltage and current should be avoided from exceeding the usage range
(2) It is strictly prohibited to directly connect magnetic switches to the power supply. They must be used in series with the load (such as relays, etc.)
(3) To connect the magnetic switch, it is necessary to confirm the working power supply used. When using a DC power supply, the red wire of the magnetic switch should be connected to the positive side of the power supply.
(4) Please avoid using magnetic switch cylinders in environments with strong magnetic fields and high currents. If you want to use them, please add shielding devices
Choose cylinder accessories: Select cylinder accessories according to the requirements of action and connection

feature
High resolution, long distance, wide practical range, wide frequency response, and high reliability. Equipped with an amplification and shaping circuit, the output is a square wave signal with stable amplitude, which can achieve long-distance transmission.

appearance

The sensor housing is made of stainless steel material.

The waterproof structure is simple, with strong pressure resistance and reliable sealing, and no waterproof adhesive is used.

Product Application

Due to the stainless steel material used for the sensor housing, the sensor is sturdy and durable, and is mainly used in poor testing environments with severe vibrations (such as engines, etc.). Used for measuring speed, cycle, and velocity.
