The Gagalor C-40-4 NC Wired Door Alarm Magnetic Contact Sensor Double-Sided Adhesive is a versatile security component designed to provide reliable protection against unwanted intrusion. This sensor is equipped with a magnetic contact that can be used to monitor the opening and closing of doors or windows.
The sensor comes with a wired design that allows for easy integration with existing wired alarm systems. It utilizes a Normally Closed (NC) circuit, which means that the alarm is not activated when the door or window is closed and the magnetic contacts are in contact. Once the door or window is opened, the magnetic contacts are separated, completing the circuit and triggering the alarm.
The sensor also features double-sided adhesive tape, making it simple and convenient to install. The adhesive is strong enough to securely attach the sensor to a wide range of surfaces, including doors, windows, and walls. The sensor's compact size, measuring 3.5 x 2.5 inches, ensures that it can be installed discreetly, allowing it to blend seamlessly into its surroundings.
This magnetic contact sensor is built with high-quality components that are designed to ensure long-lasting performance. It features a weather-resistant design that can withstand various environmental conditions, making it ideal for both indoor and outdoor use. The sensor's operating temperature range is between -4 F to 158 F (-20 C to 70 C), and it can detect a door or window opening as small as 0.1 inches (2.54 mm).
The Gagalor C-40-4 NC Wired Door Alarm Magnetic Contact Sensor Double-Sided Adhesive is a reliable and cost-effective solution for enhancing the security of any property. Its easy installation, versatile design, and durable construction make it a must-have for anyone looking to protect their home or business from intruders.
