Safety sensor P51022H

*NO/NC

*AC/DC 12-24 V

*Receiving Range: 12 Meters

*IP 54

*External LED flash lamp signal (AC/DC 12V-24 V)

*Internal Rotation system: 0~180

 

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.

Safety sensor - P51033H

*NO/NC *AC/DC 12-24 V *Receiving Range: 12 Meters *IP 54 *External LED flash lamp signal (AC/DC 12V-24 V) *The P51033H safety sensor included the LED flash light   The P51033H is a safety sensor, specifically a photoelectric sensor (also known as a photo eye) commonly used in automatic gate and door systems. What it Does 🚧 This sensor functions as an obstruction detection device. It consists of two parts: an emitter and a receiver. The emitter sends out an infrared light beam, and the receiver detects it. If an object (like a person, pet, or vehicle) interrupts this beam, the sensor sends a signal to the gate or door's control board, causing it to stop or reverse its movement, preventing potential injury or damage.   Key Specifications ⚙️ Here are some of the technical details for the P51033H:
  • Working Voltage: 12~24VAC/DC
  • Working Current (24VDC):
    • Emitter:
    • Receiver:
  • Photocell Wavelength: (infrared)
  • Angle of Opposite Emission:
  • Receiver Range: (this range can be reduced by about in adverse weather conditions like fog, rain, or dust)
  • Working Temperature:
  • Relay Contact Loading Capacity:
  • Waterproof Grade: IP54
  • Size:
  • Outputs: NO/NC (Normally Open/Normally Closed) contacts
  Installation Considerations 🛠️ For optimal performance, the P51033H should be installed:
  • Height: More than above the ground to prevent false reflections.
  • Distance between Emitter and Receiver: More than meters to ensure proper operation.
  • Sunlight: The receiver should be installed away from direct sunlight or other strong light sources () to maintain stable operation.
  • Multiple Sensors: If multiple photocells are installed on the same line, receivers can be placed at both ends and emitters in the middle, back-to-back, to prevent interference.
  • Firm Installation: Install the photocell firmly to avoid signal bias between the emitter and receiver, which could lead to malfunctions.
  Safety Importance 🛡️ Safety sensors like the P51033H are crucial for automated systems like gates and doors. They provide a vital layer of protection, ensuring that the system stops or reverses if an obstacle is detected, thereby preventing accidents, injuries, and property damage.

Safety sensor - Nice Era-EPM

The Nice Era-EPM is a photoelectric safety sensor commonly used in automation systems for gates, garage doors, barriers, and similar installations. It's also often referred to as a photocell or beam sensor. Here's a breakdown of what it is and its key features: Purpose: Its primary function is to enhance safety by detecting obstacles in the path of a moving gate or door. It consists of a transmitter (TX) and a receiver (RX) that are installed facing each other. The transmitter emits an infrared beam, and if this beam is interrupted by an object, the receiver signals the control unit to stop or reverse the automation system, preventing accidents, injuries, or damage to vehicles. Key Features and Specifications:
  • Photoelectric Technology: It uses an infrared beam to detect obstructions.
  • Transmitter (TX) and Receiver (RX): Comes as a pair, with one unit transmitting the beam and the other receiving it.
  • Relay Output: It's a relay photocell, meaning it sends a signal to the control unit via a relay output.
  • Range: Typically has a useful range of 15 meters, which can be extended up to 30 meters in some configurations (e.g., by cutting a "+10m" electrical bridge). However, range can be reduced in adverse weather conditions like fog, rain, or dust.
  • Anti-Glare Circuitry: Designed with an anti-glare circuit to minimize interference from sunlight, ensuring reliable performance in various lighting conditions.
  • Durable Construction: Features an ABS body that is resistant to weather conditions, making it suitable for outdoor use (IP44 protection rating).
  • Easy Installation: Known for its simplified assembly and installation procedure. Some versions (like those with Nice BlueBUS technology) require only two wires for connection to compatible control units, simplifying wiring.
  • Wide Angle of Reception: Generally has a 10° (or 8° with a reduction cone) angle of reception, which helps in compensating for minor alignment issues.
  • Compatibility: While it's a Nice-branded product, it's often described as a "universal photocell" compatible with most gate and garage door automation systems, especially those that accept standard relay inputs. Some models also feature Nice BlueBUS technology for seamless integration with Nice control units that support it.
  • Safety Compliance: It is a Type D presence detector according to EN 12453 standard, which means it detects obstacles on the optical axis. When connected to a control unit with a "phototest" function, it can achieve Category 2 safety against malfunctions according to EN 954-1.
Installation: The Nice Era-EPM sensors are typically surface-mounted on two solid, parallel walls, facing each other to create the safety beam. Proper alignment between the transmitter and receiver is crucial for optimal operation. In essence, the Nice Era-EPM is a robust and reliable safety device designed to make automated gate and door systems safer by actively detecting obstacles in their path of operation.

Safety sensor FT2008

*NO/NC *AC/DC 12-24 V *Receiving Range: 15 Meters *IP 44
A gate opener safety sensor is a device designed to detect objects or people in the path of an automatic gate and prevent it from closing or hitting them, ensuring safety and preventing damage or injury.
These sensors can be photoelectric, pressure sensors, magnetic sensors, or loop detectors and are crucial for preventing accidents and ensuring smooth gate operation. 

Types of Gate Opener Safety Sensors:

  • Photoelectric Sensors:
    These sensors use an infrared beam to detect objects. When the beam is broken by an object, the gate opener is signaled to stop or reverse. 
  • Pressure Sensors:
    These sensors are typically located along the edge of the gate and detect pressure when the gate comes into contact with an object. 
  • Magnetic Sensors:
    These sensors use a magnetic field to detect the presence of vehicles or objects near the gate. 
  • Loop Detectors:
    These sensors use a wire loop buried in the ground near the gate. When a vehicle or object passes over the loop, it triggers the gate to stop or reverse. 
How They Work:
  1. Detection: The sensor detects the presence of an object or person in the gate's path. 
  2. Signal: The sensor sends a signal to the gate operator. 
  3. Action: The gate operator responds by stopping, reversing, or remaining open, depending on the sensor type and programmed settings. 
Importance of Safety Sensors:
  • Prevent Accidents: They protect people and vehicles from being hit by the gate. 
  • Prevent Damage: They help avoid damage to the gate, vehicles, or property. 
  • Ensure Reliable Operation: They contribute to the smooth and safe operation of the gate.
