The Keyence EM-030B proximity switch from Keyence Corporation provides non-contact detection with an NPN output and a red LED indicator to show status. It operates on 10.8–30 VDC, making it compatible with standard industrial control circuits. This compact sensor is suited to automation tasks such as part presence, position sensing, and end-of-travel detection in machinery where non-contact sensing is advantageous. Designed for systems that rely on DC power and an NPN switching configuration, the EM-030B integrates into existing control layouts with straightforward wiring.
