Hikvision Wireless External Magnetic Contact | DS-PDMCX-E-WB
The Hikvision DS-PDMCX-E-WB is a wireless opening detector made for outdoor use, with a robust plastic housing that is IP66 weather resistant and UV stable. It detects openings with a gap of up to 76 mm and communicates over Tri-X two-way 433 MHz wireless with AES-128 encryption and up to 1 km range in free space.
Key Features
Built for Outdoor Openings: The IP66 housing is UV stable and operates from -20 °C to 60 °C, so the contact can be fitted on outdoor doors and gates. Front and rear tamper protection reports attempts to open or remove it.

Large Detection Gap: The maximum detection gap is 76 mm, larger than the 52 mm of the slim indoor contact DS-PDMCS-EG2-WB. The sensor and magnetic stick are both 146 mm long.
Alarm Input: The detector has an alarm input that supports normally closed, normally open and impulse count modes. Signal strength and environment temperature indicators help during installation.

Secure Wireless and Long Battery Life: Tri-X two-way RF with AES-128 encryption and frequency hopping keeps the link secure, with up to 1 km range in free space. One CR123A battery gives a standard battery life of 5 years.
Easy Enrollment: It can be enrolled by power-up, remote ID or QR code and configured fully through the app.
