Therefore, this relay plays the role of a memory circuit. It is also known as bistable, keep impulse or lockup relay. \u003c\/p\u003e\n\u003cp\u003eA latching relay helps to reduce power dissipation in the application circuit because the coil does not need to be energized all the time. But a non-latching relay needs to be energized all the time. Therefore, a non-latching relay consumes more power compared to a latching relay.\u003c\/p\u003e\n\u003cp\u003eThe latching relay has noiseless switching for maximum comfort in household applications. Non-latching relay hums when they are operating.\u003c\/p\u003e\n\u003cp\u003eThe magnetic latching relay features low power, steady performance, long service life, and low-temperature rise. It is perfect for applications requiring low power and high stability.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eLatching or Non Latching Relay?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIt depends. The decision between latching relay vs. normal relay should be made based on the application’s requirements. For example, if power consumption is an issue and noise levels must remain low, latching relays are the way to go.\u003c\/p\u003e\n\u003cp\u003eHowever, for situations where a short time delay is needed, non-latching relays might be more economical. That’s because these relays generally cost less.\u003c\/p\u003e\n\u003cp\u003eUltimately, it is up to the designer to decide if a latching or non-latching relay is needed, and how to implement in the system. Depending on the application, there may be more than one type of relay that could work. Therefore, careful consideration must be given when making the choice.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cimg alt=\"Magnetic Latching Relay and Arduino Connection Diagram\" title=\"Magnetic Latching Relay Connection Diagram\" src=\"https:\/\/image.dfrobot.com\/image\/cache3\/data\/DFR0996\/Connection%20Diagram.png\" original=\"https:\/\/image.dfrobot.com\/image\/cache3\/data\/DFR0996\/Connection Diagram.png\"\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cb\u003eConnection Diagram of Magnetic Latching Relay and Arduino\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch4\u003eFEATURES\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eLow power consumption, 2.6mw-3.65mw\u003c\/li\u003e\n\u003cli\u003eNoiseless\u003c\/li\u003e\n\u003cli\u003eTrigger Pulse Width: 2ms\u003c\/li\u003e\n\u003cli\u003eHolding function\u003c\/li\u003e\n\u003cli\u003e3.3V \u0026amp; 5V supported Arduino \/ ESP32 \/ Raspberry Pi \/ LattePanda\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eAPPLICATIONS\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eRemaking home appliances\u003c\/li\u003e\n\u003cli\u003eLighting controls\u003c\/li\u003e\n\u003cli\u003eSmart electricity meters\u003c\/li\u003e\n\u003cli\u003eSmart lighting\u003c\/li\u003e\n\u003cli\u003eSmart sockets\u003c\/li\u003e\n\u003cli\u003eSmart switches\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eSPECIFICATION\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eSignal Level: 3.3V, 5V\u003c\/li\u003e\n\u003cli\u003ePower Voltage: 3.3V-5V DC\u003c\/li\u003e\n\u003cli\u003eTrigger Pulse Width: 2ms\u003c\/li\u003e\n\u003cli\u003eStatic Current: 0.73mA - 0.8mA(@3.3V-5V）\u003c\/li\u003e\n\u003cli\u003eCoil Operating Current: 137mA(3.3V), 93mA(5V)\u003c\/li\u003e\n\u003cli\u003eContact Resistance: ≤100mΩ (1A 6V DC)\u003c\/li\u003e\n\u003cli\u003eContact Material: AgSnO2\u003c\/li\u003e\n\u003cli\u003eContact Load: 10A 36V AC (Resistive), 15A 36V AC (Incandescent lamp)\u003c\/li\u003e\n\u003cli\u003eMax Switching Voltage: 36V AC\/30V DC\u003c\/li\u003e\n\u003cli\u003eMax Switching Current: 10A\u003c\/li\u003e\n\u003cli\u003eMax Switching Power: 36VA\/300W\u003c\/li\u003e\n\u003cli\u003eCoil Rated Power: 0.4W\u003c\/li\u003e\n\u003cli\u003eRelay Action Time(@Rated Voltage): ≤8ms\u003c\/li\u003e\n\u003cli\u003eRelay Reset Time(@Rated Voltage): ≤5ms\u003c\/li\u003e\n\u003cli\u003eOperating Humidity Range: 5%-85%RH\u003c\/li\u003e\n\u003cli\u003eOperating Temperature Range: -40℃-85℃\u003c\/li\u003e\n\u003cli\u003eProduct Dimension(Package Not Included): 42×32mm\/1.65×1.26”\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eDOCUMENTS\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/SKU_DFR0996_Magnetic_Latching_Relay\" target=\"_blank\"\u003eProduct wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch4\u003eSHIPPING LIST\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eMagnetic Latching Relay ×1\u003c\/li\u003e\n\u003cli\u003e3Pin Gravity Wire ×2\u003c\/li\u003e\n\u003c\/div\u003e","brand":"DFROBOT","offers":[{"title":"Default Title","offer_id":41099608031343,"sku":"RR-4B-DFR-DFR0996","price":11.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0011\/6464\/0314\/files\/DFR0996_9da344d9-1652-4e5a-bb54-8c8253037c44.jpg?v=1726876278","url":"https:\/\/rapidroboticsaustralia.com.au\/products\/dfr0996-gravity-magnetic-latching-relay-for-esp32-arduino","provider":"Rapid Robotics Australia","version":"1.0","type":"link"}
