650nm 5mW Dot Laser Diode Module for Photoelectric Switch Sensor

This D6mm Red 650nm 5mW Dot Laser Diode Module is a ultra-compact core component tailored for photoelectric switch sensors, integrating D6mm miniaturized housing, 650nm red laser’s high visibility, and 5mW stable dot output. It emits a sharp red dot to act as the light source for photoelectric sensing, enabling accurate object detection, position triggering, and proximity sensing—ideal for industrial automation,security, consumer electronics, and smart home photoelectric switch systems.

Core Technical Advantages for Photoelectric Switch Sensors

– D6mm Ultra-Mini Housing Design: With a diameter of only 6mm and length ≤12mm, this red dot laser diode module fits into the narrow installation spaces of compact photoelectric switch sensors (e.g., micro limit switches, small-size proximity sensors). The mini form factor eliminates spatial constraints, supporting dense arrangements in multi-sensor systems.

– 650nm Red Laser High Visibility: The 650nm wavelength is highly visible to photodiode receivers, ensuring strong signal contrast between the laser dot and ambient light. It resists interference from sunlight and indoor lighting, avoiding false triggers of the photoelectric switch—critical for reliable detection in bright industrial or outdoor environments.

– 5mW Stable Dot Output: Delivers CW mode output, projecting a uniform red dot (size ≤2mm@1m) and narrow beam divergence . The stable dot ensures consistent light intensity at the detection point, maintaining photoelectric switch triggering accuracy.
