industrialfast

Overview
The S15535 is a surface-mount two-dimensional position-sensitive detector (PSD) designed for high-accuracy position sensing in compact assemblies. It offers excellent position detectability in a smaller package than conventional models and is compatible with lead-free solder reflow.

Key features

• Surface-mount package (12.8 × 11.6 × 1.5 mm)
• Photosensitive area: 9 × 9 mm
• Peak sensitivity wavelength: 980 nm (typ.)
• Photosensitivity: 0.6 A/W (typ.)
• Spectral response: 380–1100 nm
• Low dark current and fast rise time for accurate measurements
• Compatible with lead-free solder reflow

Typical applications

• Laser beam position monitoring
• Optical alignment and tracking
• Machine vision and robotics
• Industrial position sensing
