The unit covers a 40x40 degree detection field, making it suitable for perimeter security applications where adversarial masking attempts are a concern. Anti-masking technology alerts the system when the sensor lens is blocked, sprayed, or covered, maintaining detection integrity in monitored zones. Licensed security installers and low-voltage technicians are the primary trade professionals who install and commission this sensor.\u003c\/p\u003e\n\u003cp\u003eThis sensor is intended for outdoor perimeter and access-point protection in residential and commercial security systems. The pier-mount configuration suits gate posts, fence posts, and structural columns where a fixed detection field must be maintained. The 40x40 degree coverage pattern provides a focused zone appropriate for narrow corridors, entry lanes, and defined approach paths. It is supplied as a single unit per package and integrates with compatible wireless security receiver systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40x40 degree outdoor detection pattern for focused perimeter coverage\u003c\/li\u003e\n  \u003cli\u003eAnti-masking detection alerts the system when the lens is obstructed or tampered with\u003c\/li\u003e\n  \u003cli\u003ePier-mount form factor suited for posts, columns, and structural supports\u003c\/li\u003e\n  \u003cli\u003eWireless PIR technology eliminates the need for detection-circuit wiring runs\u003c\/li\u003e\n  \u003cli\u003eOutdoor-rated construction for exterior installation environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install wireless PIR sensor for outdoor perimeter security systems accepting compatible wireless PIR inputs.

Before mounting, confirm the pier or post structure is plumb and provides a stable, vibration-free surface to prevent nuisance triggers. Power down or disarm the associated wireless receiver panel before enrolling the device to avoid false alarm events during commissioning. Do not aim the sensor directly into areas of high thermal contrast such as HVAC exhaust vents or direct sun exposure, as these conditions can affect PIR performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Pattern\u003c\/strong\u003e: 40x40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Wireless Passive Infrared (PIR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-Masking\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Pier Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Outdoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OPTEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HX-40AM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTEX","offers":[{"title":"Default Title","offer_id":51685916868914,"sku":"HX-40AM","price":667.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72302dad909707524e01b992372419c7.jpg?v=1788220613","url":"https:\/\/voomisupply.com\/products\/optex-hx-40am-wireless-pir-sensor-anti-masking-pier-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
