High Speed Door Sensors & Controls
Complete safety sensors, opening sensors, activation switches and warning devices for high speed doors, overhead doors and industrial gates in Thailand. All components are selected for Thai factory environments and can be integrated with new or existing doors.
- Photocells, light curtains & safety edges
- Radar sensors & loop detectors
- Push buttons, pull cords & remote controls
- Warning lights & traffic signals
Three Categories of Door Components
Safety sensors to protect people and goods, activation devices to operate the door, and visual/audible indicators to show door status clearly.
High Speed Door Safety Sensors
Devices installed on or around the door opening to prevent closing on people, forklifts or products.
Photocell Safety Sensors
Through-beam or reflective photoelectric sensors installed on the door frame to detect people or forklifts in the opening.
- Sensing range: 5–10 m
- 12–24 V AC/DC supply
- NPN/PNP or relay output
- IP65 housing for dusty environments
Light Curtain – Full Height
Multi-beam light curtain covering the full opening height. Creates an invisible safety wall that stops the door when anything enters.
- Sensing height: 1.8–2.0 m
- Beam spacing: 20–40 mm
- Fast response (<20 ms)
- 24 V DC, IP65, GMP suitable
Safety Edge (Bottom Sensor)
Pressure-sensitive rubber profile on the door bottom. When touching an obstacle, the door stops and reverses immediately.
- For high speed & overhead doors
- Works even if photocells blocked
- 24 V supply, IP65+
- Fast reaction time
High Speed Door Opening Sensors
Sensors to detect people, forklifts and vehicles for automatic door opening and dock protection.
Radar Sensor – Standard
Microwave radar installed above the door to detect approaching people and forklifts.
- Mounting height: 2.2–3.5 m
- Direction detection available
- 12–36 V supply
- Best for internal doors
Radar Sensor – Heavy Duty
Heavy-duty radar for large exterior openings and loading docks, detecting trucks and forklifts at longer range.
- Mounting height: 2–7 m
- Trucks, forklifts & people
- Outdoor & high wind rated
- Multiple outputs available
Inductive Loop Detector
Vehicle detector connected to wire loop buried in floor. Detects forklifts, trucks and cars reliably.
- Loop inductance: 80–300 µH
- Cable length up to ~200 m
- Relay outputs for control
- DIN-rail panel mounting
Easy Loop – Compact
Space-saving single-channel loop detector for limited panel space or smaller gate projects.
- Single-channel compact module
- Adjustable sensitivity
- For small gates & compact panels
- Same reliability as standard
Activation Switches & Remote Control
Different activators depending on traffic pattern, safety rules and user convenience.
3-Button Station
Standard manual control box with Up, Stop and Down buttons for door operation.
- Industrial 22 mm push buttons
- IP65+ for factory use
- AC 250 V / ~3 A rating
- 5–10 million operations life
Pull Cord Switch
Rope-operated switch mounted beside door or conveyor line. Pull to open or stop the door.
- Rope length up to 40–80 m
- Contact: 2NC + 1NO
- ~1 million operations life
- IP67 for harsh environments
Radio Remote Control
Handheld transmitter and receiver for remote operation from forklifts, trucks or operator stations.
- 4-button for multiple functions
- Secure rolling-code radio
- 2 relay outputs (pulse/toggle)
- 12–24 V AC/DC supply
Warning Lights & Traffic Signals
Clear visual and audible signals to keep people and forklifts safe around fast-moving doors.
Signal Tower Light
Stacked LED tower showing door status with three colours and optional buzzer.
- Red / Yellow / Green
- 24V or 220V versions
- 360° high-visibility LED
- Optional buzzer 85–90 dB
Warning Beacon
Compact LED beacon that flashes to warn of door movement or forklift traffic.
- 24V or 220V
- Single color options
- High-brightness LED
- Optional buzzer 85–90 dB
Traffic Signal Light
Compact traffic light module for door status or vehicle access (green = enter, red = stop).
- 100 mm (4″) lens diameter
- AC 85–265 V supply
- High-brightness LED
- Wall or frame mounting
Physical Protection
Guard posts protect door frames, control boxes and wall edges from forklift impact.
Guard Post
Steel tube with reinforced base plate, finished in black with 3M yellow reflective tape for high visibility.
- 3 inch diameter × 800 mm height
- Anchored to concrete floor
- Protects frames & control panels
- Size/color customizable
Purpose:
- Protects door frames from forklift/pallet impact
- Prevents damage to control panels and sensors
- Improves safety in high-traffic zones
- Low maintenance, highly durable
Customization: Size and color can be adjusted based on site layout and traffic pattern.
Component Specification Policy
The specifications shown represent minimum performance levels. Depending on availability and project requirements, OZ Door may supply equivalent or higher-spec European/Japanese components. Safety level, IP rating and electrical performance will always be equal to or better than shown.
Frequently Asked Questions
Can these sensors be installed on existing doors?
Yes. All sensors and control systems can be retrofitted to existing high speed doors and overhead doors, including doors from other brands.
Which safety sensor is best for food factories?
For GMP and food environments, we recommend a full-height IP65 light curtain combined with a safety edge for maximum protection.
Do you provide installation and wiring service?
Yes. OZ Door provides complete installation, wiring, and system testing for all sensors and control systems across Thailand.
Can the sensors connect to factory automation systems?
Yes. The devices support PLC signals, interlock systems, AGV/AMR integration, and can connect to existing factory automation systems.
Need help selecting sensors and controls for your doors?
