It detects vehicles and pedestrians within a defined detection zone and sends presence or pulse signals through relay outputs to the connected operator or controller.\u003c\/p\u003e\n\u003cp\u003eUnlike buried induction loops, the MRD-1P does not require saw-cutting, trenching, loop wire, or pavement work. Unlike a through-beam photo eye setup, it does not require a transmitter and receiver mounted across the lane from each other. The radar beam projects forward from the sensor face, allowing it to monitor a programmed zone from one side of the lane when installed and aimed correctly.\u003c\/p\u003e\n\u003cp\u003eThe MRD-1P is commonly used for barrier arm presence detection, vehicle approach detection, pulse-on-entry, pulse-on-exit, and keep-arm-up applications. The Presence output can be used to help prevent an arm from lowering or to reverse it when an obstruction is detected, while the Pulse output can be configured for entry or exit signaling.\u003c\/p\u003e\n\u003cp\u003eDetection distance is adjustable from 1 to 30 feet, and the sensor ignores objects beyond the programmed range. A 3-digit onboard display and pushbutton menu provide access to settings such as detection distance, pulse mode, pulse time, presence hold time, fail safe \/ fail secure behavior, threshold, transmit power, and off delay.\u003c\/p\u003e\n\u003cp\u003eThe MRD-1P is an access control and presence detection sensor. It is not a universal substitute for required monitored gate photo eyes, monitored edges, or other code-required entrapment protection devices unless the operator manufacturer, system design, and applicable code allow that use.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-sided radar presence sensor for access control lanes\u003c\/li\u003e\n\u003cli\u003eEMX model MRD-1P\u003c\/li\u003e\n\u003cli\u003eEMX part number EMX-1200-1\u003c\/li\u003e\n\u003cli\u003eDetects vehicles and pedestrians within a defined zone\u003c\/li\u003e\n\u003cli\u003e61 GHz radar detection technology\u003c\/li\u003e\n\u003cli\u003eAdjustable detection range from 1 ft. to 30 ft.\u003c\/li\u003e\n\u003cli\u003eDoes not require buried loop wire or pavement saw-cutting\u003c\/li\u003e\n\u003cli\u003eDoes not require equipment on the opposite side of the lane\u003c\/li\u003e\n\u003cli\u003eUseful alternative to traditional loops or opposing photo eyes in approved presence-detection applications\u003c\/li\u003e\n\u003cli\u003ePresence output for obstruction detection, keep-arm-up, or reverse input functions\u003c\/li\u003e\n\u003cli\u003ePulse output configurable for pulse-on-entry or pulse-on-exit\u003c\/li\u003e\n\u003cli\u003eDual relay output design for presence and pulse signaling\u003c\/li\u003e\n\u003cli\u003e3-digit display for setup and programming\u003c\/li\u003e\n\u003cli\u003ePushbutton configuration menu\u003c\/li\u003e\n\u003cli\u003eAdjustable presence hold time, pulse time, threshold, transmit power, and off delay\u003c\/li\u003e\n\u003cli\u003eFail open or fail closed configuration\u003c\/li\u003e\n\u003cli\u003eMicrowave beam is not affected by rain, snow, ice, fog, or sunlight\u003c\/li\u003e\n\u003cli\u003eDetachable screw terminal block for wiring\u003c\/li\u003e\n\u003cli\u003eBall and socket mounting bracket for aiming the detection zone\u003c\/li\u003e\n\u003cli\u003e1\/2 in.

Its single-sided design can reduce the need for buried loops or opposing photo eye-style lane detection in approved applications, while the adjustable range, relay outputs, 3-digit programming display, NEMA 4X enclosure, and 61 GHz radar sensing make it useful for many vehicle and pedestrian detection layouts. Required monitored safety devices must still be selected according to the operator, site layout, and applicable code.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ca class=\"elite-button\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/MRD-1P_specs.pdf\" target=\"_blank\"\u003eCut Sheet\u003c\/a\u003e\n\u003ca class=\"elite-button\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/MRD-1P_manual.pdf\" target=\"_blank\"\u003eInstallation \/ User Manual\u003c\/a\u003e\n\u003c\/div\u003e","brand":"EMX","offers":[{"title":"Default Title","offer_id":49195817271604,"sku":"EMX-1200-1","price":444.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0141\/9617\/8998\/files\/MRD-1Pfrontview.jpg?v=1784583986","url":"https:\/\/elitegates.net\/products\/emx-mrd-1p-radar-presence-vehicle-sensor","provider":"Elite Gates","version":"1.0","type":"link"}
