The IDEC SA2E-BN3C is a BGS photoelectric sensor equipped with an NPN output and a red LED for precise object detection. Its background suppression feature and adjustable beam diameter, which can be reduced by 30 to 40%, enhance the accuracy of position detection. The sensor includes a knob for easy setting of the sensing range and is designed for optimal performance in cold storage environments. Additionally, it offers built-in reverse-polarity protection to prevent damage from incorrect wiring and utilizes an M8 connector for secure electrical connections.
