 Application<\/strong><\/p>\n\n\n\n

  The product adopts a standard round tube waterproof structure, which has the advantages of being waterproof, dustproof, and oil-proof, and can work reliably in harsh environments. It is suitable for control fields such as automobiles and industrial automation.<\/p>\n\n\n\n

  Features<\/strong><\/p>\n\n\n\n

  SM39 series gear speed sensor is an advanced speed sensor used for non-contact detection of gear speed. It outputs square wave signals in OC gate mode with strong anti-electromagnetic interference ability. It can be directly connected to TTL, CMOS and other logic circuits after adjusting the pull-up resistor. It can form a speed measurement and control system when matched with a speed meter.<\/p>\n\n\n\n
