Area Sensor vs Safety Light Curtain
The terms Area Sensor and Safety Light Curtain can overlap in industrial applications, but they should not automatically be treated as identical technical classifications.
An Area Sensor generally describes a multi-beam photoelectric detection device.
A safety-rated light curtain is normally associated with specific functional-safety requirements and applicable safety standards.
For the DPR-1240-PNP-NC page, DAPPRA should therefore clearly describe the product as:
Industrial Area Sensor / Safety Light Curtain for Machine Protection
The DPR-1240-PNP-NC has obtained SIL 2 Functional Safety Certification according to IEC 61508 through third-party testing and certification. The SIL 2 certification should be considered together with the product's documented safety characteristics and intended machine-protection applications.
