If you’re looking for a reliable and efficient way to control lighting fixtures, 2 wire photocell sensors are the way to go. These sensors are widely used in outdoor lighting applications and offer several benefits. In this article, we’ll discuss the basics of 2 wire photocell sensor wiring diagram and everything you need to know to get started.
What is a 2 Wire Photocell Sensor?
A 2 wire photocell sensor is an electronic component that detects and measures light levels. It is commonly used in lighting systems to automatically switch lights on and off based on the ambient light level. A photocell sensor contains a photocell, which is a device that converts light energy into an electrical signal. The sensor is wired to the lighting circuit to control the lighting fixtures.
2 wire photocell sensors are also known as photoelectric sensors or light sensors. They are designed to provide energy-efficient lighting solutions for outdoor applications.
How Does a 2 Wire Photocell Sensor Work?
When the light levels fall below a certain threshold, the photocell sensor sends a signal to the lighting circuit to switch on the lights. Conversely, when the light levels rise above a certain threshold, the sensor sends a signal to turn off the lights. This process is automatic and does not require any manual intervention.
The sensor is wired to the lighting circuit using two wires – a hot wire and a neutral wire. These wires are connected to the corresponding terminals on the sensor. When the circuit is complete, the sensor can detect the ambient light level and switch the lights accordingly.
Benefits of Using 2 Wire Photocell Sensors
There are several benefits of using 2 wire photocell sensors in outdoor lighting applications. Some of these benefits include:
| Benefits | Description |
|---|---|
| Energy Efficiency | 2 wire photocell sensors can save energy by automatically switching off lights when there is sufficient natural light. |
| Increased Lifespan of Lighting Fixtures | By reducing the amount of time that lights are on, 2 wire photocell sensors can increase the lifespan of lighting fixtures. |
| Convenience | With automatic switching, you don’t have to manually turn lights on and off, saving you time and effort. |
| Cost Savings | 2 wire photocell sensors can save on electricity costs by reducing the amount of time lighting fixtures are on. |

Wiring Requirements
Before you begin wiring your 2 wire photocell sensor, it’s important to understand the wiring requirements. The following requirements must be met:
- The incoming hot wire must be connected to the hot terminal on the sensor.
- The outgoing hot wire must be connected to the load terminal on the sensor.
- The neutral wire must be connected to the neutral terminal on the sensor.
Step-by-Step Wiring Guide
Follow these steps to wire your 2 wire photocell sensor:
- Turn off the power to the lighting circuit by switching off the circuit breaker or removing the fuse.
- Locate the wires that connect the lighting fixtures to the power source.
- Disconnect the wires from the power source.
- Connect the incoming hot wire from the power source to the hot terminal on the sensor.
- Connect the outgoing hot wire from the sensor to the wires that lead to the lighting fixtures.
- Connect the neutral wire from the power source to the neutral terminal on the sensor.
- Turn on the power to the lighting circuit.
Frequently Asked Questions
Here are some commonly asked questions about 2 wire photocell sensors:
Q: What is the maximum load that a 2 wire photocell sensor can handle?
A: The maximum load varies depending on the model of the sensor. Generally, a 2 wire photocell sensor can handle loads up to 1000 watts.
Q: Can 2 wire photocell sensors be used with LED lighting fixtures?
A: Yes, 2 wire photocell sensors can be used with LED lighting fixtures. However, it’s important to ensure that the sensor is compatible with LED lighting to avoid any issues with flickering or compatibility.
Q: How do I troubleshoot a 2 wire photocell sensor that’s not working?
A: Check the wiring connections to ensure that they’re secure and properly connected. If the wiring is correct, check the photocell to ensure that it’s functioning properly. If the photocell is faulty, it may need to be replaced.
Q: Can a 2 wire photocell sensor be used with a dimmer switch?
A: No, a 2 wire photocell sensor cannot be used with a dimmer switch. The sensor is designed to switch the lights on and off automatically based on the ambient light level and cannot be used in conjunction with a dimmer switch.
Q: Can 2 wire photocell sensors be used indoors?
A: Yes, 2 wire photocell sensors can be used indoors. However, they are most commonly used in outdoor lighting applications.
