E3RA-RP21 Overview

In order for the photoelectric sensor to work reliably, it should be set to -25°C~55°C degrees Celsius. If you want these electronic components to work, you need to apply 10V~30V. A photoelectric sensor should have a response time of 500μs. It is essential that photoelectric sensors operate at a minimum working temperature of -25°C to ensure their reliability. It is possible to operate reliably at a maximum operating temperature of 55°C. You've got to connect the 4 pins to the photoelectric sensor for it to work. It needs a current of 100mA at the output to work. Photoelectric sensors can be damaged by voltages up to 30V in DC circuits. Photoelectric sensors can operate at low voltages, such as 10V. As a convenience, the Radial package includes photoelectric sensors.
