The Omron E3Z-LS66-UL is a distance-settable compact photoelectric sensor designed for high-speed, high-precision object detection in tight industrial setups. It features a red LED (670 nm) light source and a variable incident threshold, offering flexible detection from 40 mm (minimum) to 200 mm (maximum) based on the fiber guide sensor (FGS) settings. This makes it ideal for conveyor-based part detection, label sensing, or position control tasks where fine adjustment is required.
The sensor operates on a 12 to 24 VDC power supply (, Class 2), and consumes a maximum of 30 mA. It supports an NPN open collector output with a load power supply voltage of up to 26.4 VDC and a maximum load current of 100 mA. A fast response time of just 1 ms ensures compatibility with fast-moving applications in packaging, sorting, and electronics assembly lines.
The E3Z-LS66-UL features a 5-turn endless sensitivity adjuster for accurate tuning, along with clear status feedback through a dual-indicator system—an orange operation indicator and a green stability indicator. Its electrical design includes short-circuit protection, reverse polarity protection, and built-in mutual interference prevention for stable operation when multiple sensors are used side by side.
Built for industrial durability, the sensor operates in ambient temperatures from −25°C to 55°C and in relative humidity from 35% to 85%. It handles ambient light up to 10,000 lx (sunlight) and 3,000 lx (incandescent lamp). With vibration resistance (10 to 55 Hz, 1.5 mm double amplitude) and shock resistance (500 m/s²), the E3Z-LS66-UL performs reliably in rugged environments.
The compact housing is sealed to IP67 (IEC 60529), protecting it against dust and water spray. Its M8 4-pin connector allows for quick and secure connections in control panels or field wiring. The Omron E3Z-LS66-UL is a versatile, space-saving sensor solution suitable for a wide range of automation and detection tasks.
