10V~30V E3RA Series Single-Turn Retroreflective Connector Radial 4-Pin -25°C~55°C
E3RA-RN21 Overview
For reliable performance, the temperature of the photoelectric sensor should be set to -25°C~55°C. In order for these electronic components to work, they should be given 10V~30V voltage. For photoelectric sensors, 500μs is considered an ideal response time. To ensure reliability, the photoelectric sensor operates at a minimum working temperature of -25°C. A maximum operating temperature of 55°C ensures reliable operation. To make the photoelectric sensor work properly, 4 pins must be connected. Photoelectric sensors require an output current of 100mA to operate. Photoelectric sensors can withstand voltages up to 30V in DC circuits. Low voltages, such as 10V, are possible with this photoelectric sensor. In the Radial package, photoelectric sensors are included for convenience.
