Motorline MF40BAT Wireless Gate Safety Photocells – Battery Powered Infrared Gate Safety Sensor

Motorline MF40BAT Gate Safety Sensor | Wireless Safety Photocells

Motorline MF40BAT wireless gate safety sensor with infrared photocells and photo-electric beams. Battery-powered safety photocells for automatic gates up to 20m.

Advanced Gate Safety Sensor for Automatic Gates and Doors

The Motorline MF40BAT Safety Photocells are advanced infrared gate safety sensors designed to protect people, vehicles, and property in automatic gate and door systems. Using a photo-electric beam transmitter and receiver, these safety photocells detect obstacles across the gate opening and immediately stop or reverse gate movement when the beam is interrupted.

The MF40BAT model is specifically designed for installations where running cables is difficult or impossible. Its battery-powered transmitter and wireless operation allow installers to deploy reliable gate safety protection without trenching or wiring.

With a detection range of up to 20 metres, adjustable sensor alignment, and durable outdoor construction, the MF40BAT is ideal for residential driveways, commercial properties, car parks, and industrial gate automation systems across Australia.

Why Install Safety Photocells on Automatic Gates?

Safety photocells are an essential component of modern gate automation systems. These infrared photo-electric beams create an invisible safety barrier across the gate entrance.

When a person, vehicle, or object interrupts the beam:

• The gate motor immediately stops.

• The gate may reverse direction depending on the control board settings.

• Potential injury or property damage is prevented.

This makes gate safety sensors mandatory for many automated gate installations and recommended for residential and commercial properties.

 

Benefits of the Motorline MF40BAT Infrared Photocells

Wireless Installation – No Cabling Required

The battery-powered transmitter eliminates the need to run wires across the driveway, saving installation time and cost.

Reliable Gate Safety Protection

The infrared beam instantly detects obstacles, ensuring gates stop or reverse before contact occurs.

Flexible Installation

Adjustable alignment (180° horizontal rotation) allows installers to easily position the sensors even on uneven surfaces or complex gate layouts.

Solar Compatible Operation

Rechargeable battery versions can connect to a solar panel for maintenance-free operation, ideal for remote gates and rural properties.

Suitable for Australian Outdoor Conditions

With IP54 weather protection and wide temperature tolerance, the MF40BAT works reliably in Australian residential, commercial, and industrial environments.

 

Typical Applications

The Motorline MF40BAT safety photocells are commonly used with:

• Automatic sliding gates

• Swing gate automation systems

• Boom gates and car park barriers

• Industrial access gates

• Smart home gate systems

• Commercial driveway gates

How Infrared Gate Safety Sensors Work

Infrared safety photocells operate using two components:

1. Transmitter (TX)
Emits an invisible infrared beam across the gate entrance.

2. Receiver (RX)
Receives the beam and monitors the signal continuously.

When the beam is interrupted by a vehicle, person, or object, the receiver triggers a signal to the gate controller to stop or reverse gate movement. This simple yet reliable technology is why photo-electric safety beams are widely used in gate automation systems worldwide.

FAQ – Gate Safety Photocells

What is a gate safety sensor?

A gate safety sensor is a device that uses infrared photo-electric beams to detect obstacles in the path of an automatic gate. If the beam is interrupted, the gate stops or reverses to prevent accidents.

What are safety photocells used for?

Safety photocells protect people, vehicles, pets, and property by monitoring the gate opening and preventing the gate from closing when an obstruction is present.

Are safety photocells required for automatic gates in Australia?

Many modern gate automation systems strongly recommend or require safety photocells to meet safety standards and reduce liability risks.

What is the difference between reflective sensors and photo-electric beams?

• Reflective safety sensors use a mirror reflector on the opposite side.

• Photoelectric beam sensors (like MF40BAT) use a transmitter-receiver pair for greater reliability and longer range.

How far can the Motorline MF40BAT safety photocells detect obstacles?

The MF40BAT provides obstacle detection from approximately 1 metre up to 20 metres, depending on installation conditions.

Can the MF40BAT operate without power cables?

Yes. The transmitter runs on batteries and can optionally be powered by a solar panel and rechargeable battery, making it ideal for wireless installations.

Where should gate safety photocells be installed?

They are typically mounted on both sides of the gate opening at a height of 400–600 mm, creating a safety beam across the driveway.
