The HTM Sensors H12 Photoelectric Sensors provides subminiature, high-precision object detection tailored for space-constrained industrial automation fields like semiconductor and electronics manufacturing. These miniature rectangular sensors are engineered with an IP67 environmental rating and integrated metal mounting sleeves to withstand heavy machine vibrations and harsh environments.
The series features two primary variations:
Background Suppression (BGS) Models: These diffuse sensors use precise triangulation to detect flat, non-bright target surfaces over a 10–120 mm operating range. They completely ignore highly reflective or complex backgrounds regardless of target color or finish variations.
Thru-Beam Transmitter and Receiver Models: This configuration splits the emitter and receiver into separate housings to create an uninterrupted optical barrier over a 1-meter operating range. It functions at a rapid 800 Hz switching frequency, making it ideal for high-speed counting and reliable edge positioning of opaque or vibrating objects.
