Safety edges are essential for any electric gate or barrier to prevent trapping points and collisions. They are sensitive strips that detect obstructions or pressure and stop the operation to avoid harm. When the safety edge encounters an obstacle, it signals the control panel to stop and reverse the motor. Safety edges can be easily installed by screwing the aluminium profile to the gate or post and clicking the rubber profile into place. They can be cut to any length and are available in different depths, ranging from 15mm to 85mm. When ordering an electric safety edge, it is important to ensure that it complies with EU and UK legislation and safety standards.

Safety edge requirements
Safety edges are essential in preventing accidents and injuries in public, industrial, and automated settings. They are sensitive strips attached to moving machinery or equipment such as automatic gates, doors, and platforms. Safety edges are also known as safety bump strips or safety ribs and are designed to detect any obstructions or pressure, immediately stopping the operation to avoid harm.
Safety edges are "contact" devices that operate when touched using pressure-sensitive sensors. When the rubber of the safety edge comes into contact with an obstacle, it instantly triggers an automatic stop. The safety edge prevents damage and injuries that could occur if the gate or machinery was allowed to continue operating.
There are different types of safety edges available, including electrical systems that work according to the "normally open" principle, and opto-electronic safety edges that require a special signal processing module. Haake safety edges, for example, work according to the "normally closed" principle, which is a fail-safe method that does not require a separate safety module.
When ordering an electric safety edge, it is important to consider the specific requirements and applications. Custom-made safety edges can be manufactured according to individual needs, ensuring compliance with relevant standards and directives. It is also crucial to conduct a full risk assessment to identify potential hazards and determine the appropriate size and positioning of the safety edge to maximize safety and minimize risks.
The installation process for safety edges varies depending on the specific product and application. Some safety edges are designed for easy installation, requiring no glue and offering flexibility in mounting options. It is recommended to consult with professionals or technical teams to ensure proper installation and compliance with legislation and safety standards.

Safety edge types
Safety edges are essential in preventing accidents and injuries in public, industrial, and automated settings. They are typically attached to moving machinery or equipment such as automatic gates, doors, and platforms. Safety edges are also referred to as safety bump strips or safety ribs. They are designed to detect any obstructions or pressure and immediately stop the operation to avoid harm.
There are various types of safety edges available, each with its own unique characteristics and applications. Here are some of the most common types:
Taught Wire Safety Edges
Taught wire safety edges are large rubber edges suitable for fast-closing gaps. They offer good mechanical protection and can detect pressure from three directions. A wire runs the full length of the edge under tension, and when pressed, it triggers a micro-switch inside. These safety edges are often used on the leading edge of sliding gates.
Hinge Strip Safety Edges
Hinge strip safety edges are another type of mechanical safety edge commonly used. They are typically made of rubber and provide a soft buffer against potential hazards. Hinge strip edges are activated by pressure or touch and are easy to install.
ASO Sentir Safety Edges
ASO Sentir Safety Edges, such as the GF25.30, GF25.45, and GF35.55 models, are pressure-sensitive contact safety edges. They are designed to be applied to gates to ensure the safety of closing edges and prevent potential hazards such as crushing and shearing damage.
HSC Safety Edges
HSC safety edges from Haake feature a patented contact chain with electrically conductive contact rollers. These safety edges are used for machine safety, particularly in access technology such as industrial gates. They are touch-sensitive and can detect contact with a person or object, triggering an immediate response to prevent injuries.
Infrared Transmission Safety Edges
Infrared transmission safety edges are a version of battery photobeam systems. They are often used on sliding gates, with the receiver fixed near the motor. Infrared transmission is reliable, easy to install, and cost-effective, but it requires alignment.
Radio Wireless Safety Edges
Radio wireless safety edges are becoming more common due to their long range and lack of alignment needs. However, they may conflict with safety radio signals and remote controls, so separate channels are necessary. These safety edges are often used in automatic gate applications.

Safety edge installation
Safety edges are important safety devices that can be installed on automated gates and doors to prevent crushing, impact, and shearing points. They are designed with a rubber profile that compresses to provide protection for people and objects from crushing. When the safety edge comes into contact with an obstacle, it signals the control panel to stop and reverse the motor, preventing damage and injuries.
Before installing a safety edge, it is important to conduct a full risk assessment to identify potential hazards and determine the appropriate safety equipment needed. The size and positioning of the safety edge are crucial to ensure maximum protection. It is recommended to combine safety edges with photocells to enhance safety and avoid all potential hazards.
The installation process for safety edges involves fixing the aluminium profile to the gate or post using screws or rivets. The recommended distance between fixing holes is 300mm. When fitting the aluminium strip, ensure it is not twisted and is flush with the surface. For CoverLine safety edges, fold the edge over and fit it to the aluminium strip. For SlimLine, StandardLine, and ClickLine safety edges, click the edge into the aluminium rail over the full length.
It is important to ensure that the safety edge is functioning properly after installation. If the safety edge activates in error, troubleshoot by checking for issues such as protruding screws, bunched-up cables, or a twisted safety edge. Regular maintenance and inspections are necessary to ensure the safety edge remains in good condition and complies with safety standards.
When connecting multiple safety edges in series, follow the guidelines provided by the manufacturer. Ensure proper sealing against moisture ingress to prevent water damage and fluctuations in resistance. Additionally, use a maximum of four edges wired in series to maintain the operating tolerance of the circuit.

Safety edge maintenance
Safety edges are essential for any gate to ensure safety by preventing trapping points and collisions. They are rubber profiles with a contact strip in the middle that triggers an automatic stop when the strip detects any contact. They are easy to install and can be fixed by screwing the aluminium profile to the gate or post. The rubber profile clicks into place once the mounting tracks have been positioned.
To be the most effective, the safety edge should match the size of the space. A full risk assessment should be conducted to highlight any potential areas for crushing, trapping or shearing, and to ensure that appropriate safety equipment is fitted. Safety edges should be checked regularly to ensure they are working properly and show no signs of wear and tear.
Safety edges can be used in conjunction with other safety solutions, such as photocells and BEA lasers. In fact, it is recommended to use a combination of safety edges and photocells to improve safety and avoid all potential hazards.
Safety edges are also available in different sizes, with larger safety edges being safer than smaller ones. The smaller depth safety edges, such as 15mm, are ideal for trapping fingers and small trapping points.
If you have an automated door or gate system, you may need to install safety edges to comply with EU and UK legislation.
