Product Description

LoRaWAN Magnetic switch sensor

WxS Ext-021DM

LoRaWAN Magnetic switch sensor

Product Highlights

ü  Non-contact magnetic field working principle is an intrinsically safe security product.

ü  Intrusion behavior judgment, the alarm trigger is stable and reliable, and there is no false alarm.

ü  Cross-threshold report, plus periodic report every 2 hours (the threshold and the periodic report cycle are both user-configurable)

ü  OTA (Over The Air) firmware upgrade, including to upgrade loader and application images

ü  Analog and digital interface for external sensor connectivity and pulse counting (MPI)

ü  Low power consumption, 5 – 10 years of battery operational life with 2 x AA Li-SOCI2 Battery

ü  Optional DC 5V power source

ü  Integrated internal antenna, or optional external SMA/IPEX antenna

ü  Up to 5km reach in NLoS (Non-Line-of-Sight) and up to 18km LoS (Line-of-Sight) environments

ü  IP67 enclosure rating

Installation Guide

Below diagram shows the general installation guide for WxS9800, it can be installed on any flat and solid surface, the lid is contacted with the surface and fixed via 2 self-tapping screws:



Below is the recommendation of the self-tapping screw and its sizes:


Product process description

The magnetic switch is mainly composed of a switch and a magnet. The switch part is connected by a reed switch through a lead wire, and is shaped and packaged. The magnet portion is selected to respond to the magnetic field strength and is encapsulated in a plastic or alloy housing. When the two are separated or close to a certain distance, the switch is opened and closed, thereby sensing the change of the position of the object.
