The HT15-G Photoelectric Speed Sensor is an advanced rotational speed detection device based on the photoelectric effect. It features a slotless design to eliminate issues caused by light-slot blockage and employs area light source technology for enhanced anti- interference performance. With a dual-row bearing structure, the sensor offers improved bearing reliability, while multiple sealing mechanisms ensure a high IP protection rating. It supports flexible channel configuration with electrical isolation between channels, and offers a variety of pulse count options to meet different application needs. Designed for contact-based speed measurement, the HT15-G provides multiple connection interfaces, and its use of low-temperature-resistant rubber tubing makes it ideal for operation in extremely cold environments.
