Connect the plug correctly according to the wiring diagram.\u003cbr\u003e2. The Hall effect switch is a normally open NPN type, and the detection distance of the Hall effect switch must be within 10 mm. The installation diameter of the Hall effect switch is 12 mm and the cable length is 1 m.\u003cbr\u003e3. Strong electromagnetic interference should be avoided. It is better to use shielded cable or twisted pair for the measuring lead.\u003cbr\u003e4. The counter's counting signal and the switch or circuit of the reset signal input should be located as close as possible to the counter's terminal, and the signal line should be as short as possible.\u003cbr\u003e5. Avoid using the same conduit or twisted wiring with others, such as...\u003cbr\u003e6. It is not recommended to use mechanical switches or microswitches, as their lifespan is relatively short and miscounts can easily occur after a long time;\u003cbr\u003eIf you are using mechanical or microswitches, please try to use higher quality ones to avoid confusion. A strong magnetic switch is recommended.\u003cbr\u003e\u003cbr\u003ePackage includes:\u003cbr\u003e1 x LED tachometer\u003cbr\u003e1 x NPN Hall proximity sensor\u003cbr\u003e1 x Magnet\u003c\/span\u003e\u003c\/p\u003e  \u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e  \u003cp\u003e  \u003c\/p\u003e  \u003cp\u003eGuarantee:\u003c\/p\u003e  \u003cp\u003eReturns: Customers have the right to request a return within 60 days of receiving the product.\u003c\/p\u003e  \u003cp\u003e24-hour online expert support: Solve your installation and product problems\u003c\/p\u003e  \u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"viprh","offers":[{"title":"Blue","offer_id":41714097094795,"sku":"I018-A036-Blu","price":14.77,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0605\/2574\/0171\/files\/I018-A036-Set-SKU1.jpg?v=1699863907","url":"https:\/\/viprh.com\/en-gb\/products\/4-digital-led-tachometer-drehzahlmesser-drehzahlmesser-hallschalter-naherung","provider":"viprh","version":"1.0","type":"link"}
