The P51022H is a safety sensor, specifically a photoelectric sensor, commonly used in automated gate and garage door opener systems.
Functionality
Like most photoelectric safety sensors, the P51022H works by:
- Transmitting an infrared light beam: One part of the sensor (the emitter) sends out an invisible light beam.
- Receiving the beam: The other part of the sensor (the receiver) is designed to detect this beam.
- Obstruction detection: If something breaks the infrared beam while the gate or door is closing, the receiver instantly signals the opener to stop or reverse its movement. This prevents the door or gate from closing on people, pets, or objects, thus enhancing safety and preventing damage.
Applications
The P51022H is primarily used in:
- Automated gate openers: For both single swing and sliding gates, ensuring they don't close on anything in their path.
- Garage door openers: A mandatory safety feature in most modern residential garage doors, preventing accidents.
Key Characteristics
Based on available information for similar safety sensors:
- Type: Photoelectric sensor (often referred to as "photo eyes" or "safety beams").
- Components: Typically comes as a kit including a sending sensor (emitter) and a receiving sensor.
- Installation Height: These sensors are usually installed a few inches (e.g., 6 inches) above the ground to effectively detect obstacles, including small children or pets.
- Voltage: Similar sensors often operate on 12-24V AC/DC.
It's worth noting that this specific model, P51022H, is listed as an accessory for gate opener systems, and there might be an alternative model, P51033H, which is also a photoelectric safety sensor with an integrated flashlight.
