EX-Z Series Ultra-minute Photoelectric Sensor Panasonic EX-Z series ultra-minute photoelectric sensors with built in amplifier. The compact size allows installation of sensors in a narrow space where only a conventional fiber sensor head could be installed before. The built-in amplifier also saves on installation space. Sensing Capability A slit is provided on the front side of the main sensor body allowing the sensor to detect a 0.3 mm diameter object without using an optional slit. High-brightness 4-element red LED provides strong light emission over a long period of time. With the spotlight clearly visible, the sensing position can be easily confirmed. Features and Benefits Front sensing or side sensing type IP67 rated 3 sensing range models: 50mm, 200mm or 500mm
