Garage doors are essential, for keeping our homes secure and convenient. Garage door sensors are now a part of improving the safety and operation of these doors. In this guide we’ll take a dive into the realm of garage door contact sensors covering their functions, operational mechanisms, problem solving advice and all the essential details you should be aware of. Let’s begin!

What is a Garage Door Contact Sensor?

Garage door contact sensors, commonly referred to as garage door sensors serve as safety measures, on automated garage doors. These sensors are specifically created to recognize any objects or obstacles in the way of the garage door when it is, in the process of closing. Their primary function is to avert accidents and injuries by ensuring that the door does not shut on individuals, animals or items.

The Purpose of Garage Door Contact Sensors

Garage door contact sensors serve a role, in improving safety by acting as a safe measure to stop the garage door from closing if there is an obstruction. This feature is especially vital for families with children or pets who might accidentally come near the closing garage door.

Homeowners find reassurance in knowing that contact sensors minimize the chances of accidents or harm from a closing garage door. Furthermore these sensors offer added protection, for vehicles and valuable items reducing the risk of damage.

How Do Garage Door Contact Sensors Work?

Garage door contact sensors operate by using technology to identify obstacles in the way of the garage door as it closes. These sensors are made up of two parts; the transmitting unit and the receiving unit. Let’s delve into the fundamentals of contact sensor technology and why having a clear line of sight is crucial.

The Basics of Contact Sensor Technology

Contact sensors work by using a beam of light that is interrupted. One unit sends out the beam and another unit receives it. As the garage door closes, a constant beam of travels, between these units. If something blocks or disrupts this beam the sensors notice it. Make the door stop closing and go up.

The Importance of Line of Sight

To ensure that garage door contact sensors work correctly it’s crucial to keep a path, between the sending and receiving units. Position the sensors to allow the light beam to pass through unimpeded without any obstacles or misalignments that could cause the sensors to malfunction.

The Evolution of Garage Door Contact Sensors

Contact sensors, for garage doors have evolved greatly over time. Initially garage doors had to be opened and closed manually which was quite a task. The introduction of electric garage door openers in the 1920s marked an improvement in the convenience and safety of operating garage doors.

It wasn’t until the 1990s that safety standards required contact sensors to be incorporated into all electric garage door openers. This legal requirement was an advancement in ensuring accidents and injuries, from closing garage doors were minimized.
