It is designed to stop hazardous motion when an operator or object enters the field, meeting the requirements of IEC 61496 for electro-sensitive protective equipment (ESPE). The 'B0945P25' in the order code indicates a 945 mm protected height and 25 mm resolution, which means it detects fingers or hand-sized intrusions (finger-protection class) reaching toward a hazard zone. This is the type of part you specify into a guarding circuit on a press, robot cell, or assembly line where personnel access must be monitored without physical barriers.
The 25 mm resolution is the key selection parameter: it determines the smallest object the curtain detects. At 25 mm, it catches fingers (typically >14 mm) and hands, making it suitable for point-of-operation guarding where an operator reaches into the machine. The 945 mm protected height covers a vertical zone that spans typical torso-to-knee access on a standing operator. The bulk package means the unit ships as a single-piece assembly — emitter, receiver, and cabling — not as separate modules. For installation, the emitter and receiver mount on opposing sides of the guarded opening, aligned optically; the control output connects to a safety PLC or safety relay that initiates the stop command.
