German RSF Elektronik encoder RSF Elektronik model RSF Elektronik price

RSF Elektronik encoders belong to the detection and transmission link in closed-loop control. They are used to detect the rotor magnetic field position of servo motors, provide accurate motor speed and position signals, and then the magnetic encoder outputs signals to the drive for analysis, comparison, and logical judgment, finally driving the servo motor. In fact, a magnetic encoder is a sensor that constantly provides accurate signals to the drive to facilitate its accurate analysis and judgment.

RSF Elektronik encoder advantages

Encoder advantages: small size, high precision, inherently high resolution, non-contact and wear-free; the same type can detect angular displacement and, with the help of mechanical conversion devices, linear displacement; multi-turn absolute optical encoders can detect linear displacement over a considerable range (such as 25-bit multi-turn). Long service life, flexible installation, rich interface options, reasonable price. Mature technology, widely applied domestically and internationally for many years. Advantages of static magnetic grid absolute encoders: moderate size, direct measurement of linear displacement, absolute digital coding, theoretically unlimited range; non-contact and wear-free, resistant to harsh environments, usable underwater at 1000 meters; rich interface options, diverse measurement methods; acceptable price.

RSF Elektronik encoder application areas

Compared with traditional optical and grating encoders, magneto-electric encoders offer better resistance to vibration, corrosion, pollution, interference, and wider temperature ranges, making them suitable for applications where traditional optical encoders cannot adapt. Magnetic encoders are specifically designed for extremely harsh environments, which generally require wide temperature characteristics, the ability to withstand strong vibration and impact, and high protection ratings. In addition, we have reliable signal output circuits and simple installation methods, which can greatly reduce losses from downtime. They are typically used in metallurgy, papermaking, and woodworking machinery. High-performance magnetic encoders are widely used in industrial control, mechanical manufacturing, ships, textiles, printing, aviation, aerospace, radar, communications, military industry, and other fields.

RSF Elektronik encoder wiring method

A rotary encoder is a photoelectric rotary measuring device that directly converts the measured angular displacement into digital signals (high-speed pulse signals). Encoders are classified by signal principle into incremental encoders and absolute encoders. We commonly use incremental encoders, which can input the output pulse signals of the rotary encoder directly into the PLC, using the PLC's high-speed counter to count the pulse signals to obtain measurement results. Different models of rotary encoders have different numbers of output pulse phases; some rotary encoders output A, B, and Z three-phase pulses, some only have A and B two-phase pulses, and the simplest has only A phase. The encoder has 5 lead wires, of which 3 are pulse output wires, 1 is the COM terminal wire, and 1 is the power supply wire (OC gate output type). The encoder's power supply can be an external power source or directly use the PLC's DC24V power supply. The power supply "-" terminal must be connected to the encoder's COM terminal, and "+" to the encoder's power terminal. The encoder's COM terminal is connected to the PLC input COM terminal, A, B, and Z two-phase pulse output lines are directly connected to the PLC's input terminals, A and B are pulses with a phase difference of 90 degrees, and the Z phase signal has only one pulse per encoder revolution, usually used as a zero reference; pay attention to the PLC input response time when connecting. The rotary encoder also has a shielded wire, which must be grounded during use to improve anti-interference performance.
