Factors That Influence Wire Gauge Selection

When it comes to the wire gauge selection for your garage door sensors, several essential details come into play. Firstly, the distance between the sensor and opener is significant – the longer the distance, the larger the wire gauge required.

Secondly, the nature of the sensor installation matters. For instance, if the sensor’s installed through walls or along ceilings, a higher gauge wire might be necessary to withstand potential environmental harm.

Lastly, examining the electric current load is crucial. If the sensor requires more power, a larger wire gauge could be needed to handle the increased load.

Comparison of Popular Wire Gauges for Sensors

On the market, 18, 20, and 22-gauge wires are common choices for garage door sensors.

  • 22-gauge wires, smaller in size, tend to be the go-to choice for shorter distances. As examples, sensors located close to the opener or typical residential installations often opt for this size.
  • 20-gauge wires, slightly larger, can be beneficial for intermediate distances. If your garage door opener is further from the sensor or if the installation runs through hard-to-reach areas, you might find this gauge suitable.
  • 18-gauge wires, the largest of the three, are often handy for long-distance or high-power installations.

Remember, while these gauges are the most common, the perfect match for your sensor might fall outside this range. Always consider the specific requirements of your setup before making a decision.
