Protection Height Calculation

For DPR Series Area Sensors, protection height is calculated as:

Protection Height = (Beam Quantity − 1) × Optical Axis Pitch

For DPR-1640-NPN-NC:

(16 − 1) × 40 mm = 600 mm

NPN NC Signal Logic

The DPR-1640-NPN-NC uses an NPN output with NC (Normally Closed) signal logic.

Detection Condition	Output Status
Normal beam condition	Output follows NC signal logic.
Beam interruption	Output changes according to NC switching state.
