Autonics BWP20 Safety Light Curtain — Through-Beam Area

Key Features and Performance

Autonics BWP20 safety light curtain projects an infrared detection grid between emitter and receiver units, triggering output when any object breaks one or more beam axes. The 20mm optical pitch — the distance between adjacent beam axes — determines the minimum detectable object size, making BWP20 suitable for detecting hands, workpieces, and packages traversing the sensing area.

Operating range from 0.1 to 5 metres accommodates both compact machine openings and wide conveyor detection zones. The 850nm infrared light source remains invisible to operators, eliminating visual distraction on the production floor. Response time under 7ms ensures rapid detection that keeps pace with high-speed automation cycles.

Axis configurations from 8 to 20 beams create detection heights matching specific machine guarding requirements. The modular approach means Malaysian factories select exactly the detection coverage needed — no oversized or undersized installations.

IP40 protection rating suits indoor manufacturing environments where the light curtain operates within machine enclosures or production area perimeters. Indicator LEDs on both emitter and receiver units confirm alignment status and beam condition during installation and maintenance, reducing commissioning time.

NPN and PNP output options interface directly with PLC safety inputs and relay modules. Mutual interference prevention allows multiple BWP20 units to operate in close proximity without cross-talk — essential for multi-station installations common in Malaysian assembly and packaging lines.

Compact beam profiles maintain detection accuracy across the full operating range without excessive beam spread that would cause false triggers from adjacent objects.

Technical Specifications

Applications in Malaysian Industry

Autonics BWP20 safety light curtain protects personnel and monitors processes across Malaysian manufacturing facilities. Press shops in the Klang Valley install BWP20 to detect operator hand intrusion near press point-of-operation zones. Packaging lines across Malaysia use BWP20 for box and carton detection at conveyor transfer points, triggering downstream equipment based on product presence.

Electronics assembly in Penang deploys BWP20 for component presence verification on automated insertion and placement machines. Palletising stations in Malaysian logistics centres use BWP20 to detect pallet load height and position. These detection and guarding applications support NIMP 2030 workplace safety objectives while maintaining production throughput in Malaysian factories.

Autonics BWP20 vs Alternatives

Autonics BWP20 delivers area detection capability at a fraction of the cost of safety-certified light curtains from Keyence, Sick, and Banner. For applications where Type 4 safety certification is not mandated — parts detection, counting, and non-safety guarding — BWP20 provides equivalent optical performance with faster procurement and lower total cost. The 20mm pitch detects objects larger than a finger, suitable for hand detection in risk-assessed guarding applications. For PLd/SIL2 safety-rated requirements, dedicated safety light curtains are necessary.

Frequently Asked Questions

What is the detection resolution of the Autonics BWP20?

Autonics BWP20 detects objects 20mm or larger in diameter passing through the beam curtain. The 20mm optical pitch means any object breaking at least one beam axis triggers the output — suitable for hand detection, package sensing, and workpiece monitoring.

How far apart can BWP20 emitter and receiver be mounted?

BWP20 operates at emitter-to-receiver distances from 0.1 to 5 metres. Optimal alignment at longer distances requires careful mounting on rigid structures to prevent vibration-induced misalignment. Flextech Industrial provides mounting recommendations for Malaysian factory installations.

Can multiple BWP20 units operate near each other?

BWP20 includes mutual interference prevention coding that allows multiple units to operate in close proximity without cross-talk between adjacent light curtains. This enables multi-point detection on closely spaced workstations common in Malaysian assembly lines.

Is BWP20 suitable for safety-rated machine guarding in Malaysia?

BWP20 provides area detection suitable for non-safety-rated guarding and presence sensing applications. For Malaysian machinery requiring Type 4 safety light curtains compliant with EN 61496, dedicated safety-certified models are required. Contact Our Team for guidance on safety requirements.

What is the response time of the BWP20 light curtain?

BWP20 achieves response times under 7ms from beam interruption to output switching. This speed supports high-cycle-rate machinery and fast conveyor detection applications. Request Pricing from Flextech Industrial for BWP20 configurations matching your detection speed requirements.
