Doerr Motorline MF30 Relay Photocells

The Doerr Motorline MF30 relay photocells are essential safety components designed for automated gate and door systems. These infrared sensors provide reliable obstacle detection, ensuring that gates or doors stop or reverse their movement immediately upon detecting a person, vehicle, or object in the path. Engineered for durability and consistent performance, these sensors are a critical addition to any automated access control setup, significantly reducing the risk of accidents and property damage.

Advantages

The primary benefit of the Doerr Motorline MF30 system is its robust relay-based technology, which ensures compatibility with a wide range of gate automation controllers. The infrared beam provides a precise detection zone, offering high reliability even in varying environmental conditions. Its compact design allows for discreet installation on gate pillars or walls, while the weather-resistant housing ensures long-term operation without frequent maintenance. By integrating these sensors, users gain peace of mind knowing their automated systems are equipped with a proactive safety mechanism.

Suitable for

• Residential sliding and swing gate automation
• Commercial access control systems
• Garage door safety monitoring
• Industrial gate entry points

This product may not be suitable for environments with extreme physical impact risks where heavy-duty industrial bumpers are required, as the photocells are designed for detection rather than physical impact absorption. Additionally, they are not intended for use in systems that do not support standard relay-based safety inputs.

Key specifications

• Technology: Infrared beam detection
• Output type: Relay contact
• Compatibility: Universal automated gate and door controllers
• Installation: Surface-mounted
• Safety function: Obstacle detection with stop or reverse trigger

To install the Doerr Motorline MF30, mount the transmitter and receiver units directly opposite each other on the gate pillars or walls, ensuring they are perfectly aligned to maintain a clear infrared path. Connect the relay outputs to the safety input terminals of your gate control board according to the manufacturer's wiring diagram. Once connected, power on the system and verify the alignment by checking the status indicator on the receiver unit, ensuring the beam is uninterrupted during normal operation.

What to consider before purchase

• Ensure your gate control board has a dedicated safety input for relay-based photocells.
• Verify the distance between the mounting points does not exceed the manufacturer's specified range.
• Check the available space on your gate pillars for secure mounting.

For optimal performance, regularly clean the lenses of the transmitter and receiver with a soft, dry cloth to prevent dust or debris from obstructing the infrared beam. Periodically test the safety function by interrupting the beam while the gate is in motion to ensure the system reacts correctly by stopping or reversing.
