ACI A/LLS-BB : Light Level Sensor (Resistive Output), NEMA 3R Enclosure
The A/LLS light level sensor is used for applications such as turning on or off indoor or outdoor lighting based upon the amount of available light. The sensor can be mounted in a NEMA 3R rated enclosure. In darkness, the sensor has a resistance in excess of 1M ohms, versus a resistance of less than 1.5K ohms in bright light. Typically the 0-500 is used for outdoor parking lot lighting/signage applications and the 0-100 is used for indoor lighting.
Applications
- Indoor/Outdoor Lighting Control Systems
- Building Automation Systems
