Application Range
The product adopts a standard waterproof cylindrical structure, with advantages such as waterproof, dustproof, and oil-proof, and can reliably operate in harsh environments. It is suitable for automotive and industrial automation control fields.
Functional Characteristics
The SM39 series gear speed sensor is an advanced speed sensor used for non-contact detection of gear speed. It outputs a square wave signal in a strong anti-electromagnetic interference OC gate mode. After adjustment with a pull-up resistor, it can be directly connected to TTL, CMOS, and other logic circuits. When used with a speed measuring instrument, it can constitute a speed measurement and control system.
