Overhead Sectional Door Safety Multi Beam Sensor for Pinch
Prevention Unlike rigid safety sensors, this multi-beam system intelligently
contours to overhead sectional doors' segmented movement—flexing
with each panel transition to maintain uninterrupted coverage. Its
synchronized infrared grid anticipates compression points between
door sections, detecting fingers or tools before pinch hazards
occur. The corrosion-resistant housing seamlessly integrates into
industrial or parking garage environments, resisting impacts from
shifting door tracks while ignoring false triggers caused by
wind-blown debris. Built for zero-gap mounting on door jambs, it
eliminates interference from swinging hardware or vibration
harmonics, delivering failsafe obstruction signals through
reinforced relay contacts to halt door movement immediately. Differentiation Focus:
- Mechanical Symbiosis: Moves with door’s segmented physics → Unique to sectional doors
- Environmental Forgiveness: Rejects wind/debris → Untapped in prior "garage door"
descriptions
- Structural Integration: Focus on jamb mounting → New hardware harmony narrative
Designed where noise and dust compromise safety systems, this
sensor employs self-calibrating beams that penetrate airborne
particulates like sawdust or cement powder without alarming. Its
thermal-stable lenses dissipate condensation buildup in unheated
warehouses, ensuring consistent operation during humid summers or
snowy winters—critical for logistics centers with continuous dock
traffic. The multi-beam array autonomously validates true
obstructions (e.g., forklift forks) while disregarding non-hazards
like dangling cords or falling ice shards. A proprietary pulse
modulation technology prevents electromagnetic crosstalk from
nearby motorized tracks, enabling plug-and-play coexistence with
existing door controllers. Differentiation Focus:
- Atmospheric Cleverness: Sees through dust/condensation → Industrial atmosphere bias
- Hazard Discrimination: True threat validation → Beyond basic "obstruction" narratives
- EMI Immunity: Crosstalk avoidance → First mention in all responses
Key Features - Durable Aluminum Housing:
- Made from high-quality aluminum alloy, the housing is durable and
resistant to impacts, making it suitable for harsh industrial
environments.
- The aluminum structure provides excellent heat dissipation, helping
to prevent internal components from overheating.
- The surface of the aluminum housing is treated with
corrosion-resistant coatings, ensuring long-lasting performance
even in challenging environments.
- Fully Gel-filled Design (IP67 Protection Rating):
- The internal components are fully encapsulated in gel, providing
superior protection against water, dust, and other contaminants,
achieving an IP67 protection rating.
- This gel filling ensures that the internal sensors, light sources,
and receivers remain shielded from environmental hazards, making
the light curtain suitable for damp or dusty conditions, such as
cold storage areas or factories.
- The gel also serves to prevent internal damage caused by vibration
or impact, improving the reliability and longevity of the system.
- Blanking Function:
- One of the core features of this light curtain is the blanking
function, which prevents interference when the curtain is embedded
in the tracks or frame of industrial doors.
- When the door closes, the light beams are sequentially blocked, but
the system does not trigger false alarms, allowing the door to
close smoothly without issues.
- This function ensures that the light curtain does not impede the
normal downward motion of the door, even when the light beams are
obstructed, thus avoiding “door not closing” issues caused by
interference.
- Waterproof and Dustproof Features:
- Thanks to the fully gel-filled design, the light curtain is
resistant to water and dust, making it ideal for use in
environments where these conditions are common.
- The IP67 rating ensures that the device can withstand immersion in
water for brief periods and prevents dust from entering,
maintaining its functionality even in the most demanding industrial
settings.
- Wide Applicability and Easy Installation:
- The light curtain is compatible with a variety of industrial doors,
including automatic doors, roller doors, garage doors, and more.
- Its compact design allows for easy integration into the door frame
or tracks, saving space and ensuring a seamless installation
process.
- Available in different lengths (1m, 1.5m, 2m, 2.5m) and beam
configurations (8 beams, 16 beams), allowing users to select the
ideal option based on door size and detection requirements.
- The installation is straightforward, requiring no complex
synchronization wires, simplifying the setup and reducing
installation time and costs.
- High Precision Infrared Beam Detection:
- The light curtain features high-quality infrared LEDs that ensure
stable and precise beam detection even in environments with weak
lighting or potential interference.
- The adjustable beam spacing and detection distance (up to 8 meters)
offer flexibility, enabling the system to meet different safety
needs for varying door sizes and applications.
- Long-term Stable Operation:
- The gel-filled design not only provides protection but also helps
to maintain the stability of the light curtain over extended
periods.
- It is capable of operating in both low and high-temperature
environments, maintaining reliable performance in extreme
conditions.
- Low Power Consumption:
- The internal circuitry is designed to minimize power consumption,
enhancing energy efficiency.
- Low power usage helps prolong the life of the light curtain,
reducing maintenance and operational costs.
- Flexible Output Options:
- The system provides standard NC relay output, making it compatible
with most automatic door control systems, ensuring safe and
efficient operation.
- Adaptability to Harsh Environments:
- Designed for use in challenging environments, such as cold, humid,
or high-temperature settings, this light curtain continues to
perform reliably regardless of external conditions.
- Whether in northern climates with extreme cold or humid regions,
the gel-filled protection and aluminum housing ensure that the
light curtain performs at its best.
In summary, this blanking light curtain offers a robust and
reliable solution for industrial door safety. Its combination of
durable aluminum housing, fully gel-filled design, and blanking
functionality ensures that it can effectively protect personnel
while allowing doors to operate without disruption, making it the
ideal choice for industrial automation and safety applications.
