E3FA-LP21 Overview

It is recommended to set the temperature of a photoelectric sensor to -25°C~55°C in order to ensure reliable operation. It's important that 10V~30V is applied to the circuit or system for these components to work. For photoelectric sensors, 500μs is considered an ideal response time. Reliability is ensured by working at a minimum temperature of -25°C. It is possible to operate the system reliably at temperatures up to 55°C. For the photoelectric sensor to work properly, 4 pins must be connected in order to make it work. Photoelectric sensors need 100mA at their outputs to work. A photoelectric sensor can withstand a voltage of 30V in a DC circuit without being damaged. The photoelectric sensor can operate at an extremely low voltage, such as 0 volts. As a convenience, here are some photoelectric sensors included in the 100 package.
