Item Type: Safety Light Curtain Model: BEM0420-C-60NB Material: ABS+aluminum alloy Application: Suitable for stamping machinery, shearing machinery, production line Working Voltage: 10-30V Number of Beams: 4 beams Beam Spacing: Approx. 20mm / 0.8in Protection Height: Approx. 60mm / 2.4in Detection Distance: Approx. 0.3-2m / 1-6.6ft Protection Level: IP65 Protection Mode: Short circuit protection, over current protection, reverse connection protection Working Mode: Programming synchronous scanning Output Mode: NPN NC Intelligent Design: Automatically lock to a safe state in the event of a failure Features: Anti interference Package List 2 x Light Curtain 2 x Adapter Line 1 x Accessory Kit (4 x Bolts, 4 x Nuts, 4 x Washers, 4 x Backing Rings) 1 x Manual 1. A safe distance of 300mm must be maintained between the sensor and the hazardous area2. Cannot be used for electronically controlled machines without immediate stop3. When installing, you must consider whether there are other reflectors that can malfunction 1[Far Infrared Design] Using high quality infrared lamp beads and light panel, far infrared design, strong anti light ability, can be used as a signal response quickly and accurately, greatly reducing the occurrence of accidents. 2[Stable Performance] With IP65 protection level, with short circuit, over current and reverse connection protection, back slider grooves design, good seismic performance. 3[Durable Material] Infrared light curtain sensor adopts aluminum alloy shell, with strong structure, good sealing, durable and stable, and can be used for a long time. 4[Waterproof And Sensitive] This safety light curtain is dustproof, waterproof and oilproof, to prevent foreign matter from intruding into the grating, and it is still sensitive in harsh working environments. 5[Self Check Design] Intelligent technology is adopted to protect the circuit safety self check design. If a failure occurs during work, it will be locked to a safe state to avoid accidents.
