Autonics light curtain BWP20-16P

Through-beam type, sensing distance: 0.1 to 5m, PNP open collector

The BWP20-16P is a slim plastic single-beam safety light curtain that is used to protect people against potential dangers caused by machines in hazardous areas. This product works based on the through-beam working principle which contains an emitter and a receiver in separate housings. This technology is depending on the infrared LED light source which provides accurate detection.

As a quick report, BWP20-16P from Autonics comes with the following features:

• Sensing type: Through-beam type (direct beam)
• Sensing distance: 0.1 to 5m
• Light source: Infrared LED (850nm modulated)
• Optical axis pitch: 20mm
• Number of optical axes: 16
• Power supply: 12-24VDC ±10% (ripple P-P: max. 10%)
• Control output: PNP open collector
• Operation mode: Light ON/Dark ON (set by switch)

Sensing type

This product works based on the through-beam working principle which contains an emitter and a receiver in separate housings. The emitter emits light beams toward the receiver. The device will detect the object when the light beam is interrupted.

Sensing distance

This model is able to detect the objects from 0.1 to 5 meters among the active area.

Optical axis

The number of optical axes which are emitted from the transmitter is 16 axes. The other feature of the optical axis which is called optical axis pitch is equal to 20 mm.

Control output 

The output of the BWP20-16P is PNP open collector.

Operation mode

The operation mode for this model of light curtain is based on Light ON/Dark ON.

Other features

• The maximum response time for this model is 6 ms.
• The light source is infrared LED (850 nm modulated).
• The sensing head is 300 mm and the total length is 350 mm.

Industries/applications

• End-of-line packaging
• OEM machine builders
• Automotive, integrators, and powertrain manufacturing
• Tire manufacturing
