10V~30V E3FA Series Single-Turn Reflective Connector 100 -25°C~55°C
E3FA-BN21 Overview
For reliable operation, the photoelectric sensor's temperature should be set to -25°C~55°C. If these electronic components are to work, they should receive 10V~30V voltage into the circuit or system. It is considered ideal for photoelectric sensors to have a response time of 0. For reliability, the photoelectric sensor needs a working temperature of -25°C. Operating at a maximum temperature of 55°C ensures reliable performance. Photoelectric sensor output current should be 100mA for it to operate. When applied to a DC circuit, the maximum voltage that can be applied to the photoelectric sensor without damaging it is 30V. Unlike most photoelectric sensors, this one operates at a very low voltage such as 0 volts. Photoelectric sensors are included in the 100 package as a convenience.
