The SICK LFP0200-A5NMC is a Type 4 (Category 4 according to IEC 61496-1/2) safety light curtain designed for safeguarding access points on machinery with lower risk applications. It provides a cost-effective solution for protecting personnel by creating an invisible infrared detection field. When this field is interrupted, the device sends a stop signal to the machine's safety relay or controller (PLC), halting hazardous motion.
Key Features
High Safety Integrity: Meets Type 4 / Category 4 standards, providing a high level of performance and safety for applications requiring Performance Level e (PL e) according to ISO 13849-1 or SIL 3 according to IEC 62061.
Cost-Optimized: Part of the "Inexpensive Protection" series, offering essential safety light curtain functionality at a competitive price point for simpler applications.
Compact and Slim Design: The narrow housing allows for easy integration into machinery with limited space.
Simple Setup: Features integrated alignment LEDs on both the transmitter and receiver, making installation and commissioning quick and straightforward.
Fixed Blanking Function: Allows for the permanent masking of one or two beams to accommodate for fixed obstructions within the protective field (e.g., a machine column) without compromising the safety of the overall system.
Daisy-Chaining: Multiple LFP200 systems can be connected in series ("daisy-chained") from a single power supply, simplifying wiring and reducing installation costs.
