Product Introduction
Our EX-Z Series Ultra-Minute Photoelectric Sensor is ultra-small through-beam photoelectric sensor. Adopting new semiconductor packaging technology without lead soldering, it achieves an ultra-thin 3mm housing. Integrated amplifier design eliminates the need for an external amplifier, saving installation space. Compared with EX-10 series, its volume is reduced by up to 50%. It includes front sensing and side sensing models, supporting NPN/PNP output, and optional bend-resistant cables for flexible wiring.
Key Benefits
▶Ultra-small dimension: Thickness only 3mm, suitable for narrow installation space where only fiber sensors could be placed previously.
▶Built-in amplifier structure: Simplify automation layout, reduce spare parts and assembly work.
▶Clear visible light spot: Easy position calibration during equipment debugging.
