The SICK GLL70 Series Fiber-Optic Sensor is part of a versatile line of amplifiers suitable for flexible integration of fiber-optic cabling for tight installation spaces. The OLED display supports four languages and a user-friendly navigation experience for parameterization directly at the sensor, with integrated optical feedback. The high transmitting power and continuous threshold adaptation ensures reliable detection with minimal need for maintenance. NPN and PNP digital outputs are available as standard within a single device. The GLL70 Series features a 50µs response time, supporting high detection ranges (dependent on fiber-optic cable used, see Documentation Tab).
