ELK Products ELK-319DG Wireless Door/Window Contact Sensor
The ELK-319DG is a two-piece magnetic contact sensor built for perimeter door and window monitoring on ELK security panels. It pairs a 3.39" L x 1.34" W x 0.79" D sensor body with a compact 2.36" L x 0.83" W x 0.8" magnet, giving installers a low-profile surface-mount option where a recessed contact isn't practical. The industrial gray housing is sized to blend into door and window frames rather than stand out as a visible security add-on. Model ELK-319DG runs on two CR2032 3VDC lithium coin cells, keeping the sensor wireless and eliminating a home-run wiring pull back to the panel — a meaningful time saver on retrofit jobs where fishing wire through an existing frame isn't an option.
Compatibility
The ELK-319DG is built as a wireless contact sensor for ELK security and access control installations. Confirm receiver/panel compatibility with your specific ELK control system before specifying this sensor on a job, since exact panel-to-sensor pairing isn't listed in the available documentation for this SKU.
Installation Notes
Operating range is rated -40°F to 140°F (-40°C to 60°C), which covers unconditioned spaces — attached garages, unheated stairwells, exterior-facing frames — where a standard indoor-rated contact would be a poor fit. The 3VDC coin-cell pair means no external power run is required, but budget battery replacement into your service schedule since coin cells are a maintenance item, not a one-time install cost. Mounting is magnet-to-sensor gap dependent; keep the door/window gap within the sensor's rated sense distance for reliable trip detection, and verify alignment after the door or frame is hung.
This ELK-319DG unit is NDAA-compliant, relevant for installers bidding on federal, municipal, or other government-funded projects that require sourcing verification. Pair it with the broader ELK Products catalog when you're specifying a full perimeter package, and check the access control category if you're building out a panel-based system around it. For planning sensor placement across a multi-door install, the access control planning guide covers zoning and coverage tradeoffs worth reviewing before ordering in bulk.
