The Parker SMC-1N Hall Effect Sensor Switch is a 3-wire, NPN normally-open magnetic switch designed for 6–30 V DC operation with a 150 mA draw. It features 34-inch leads for flexible mounting in automation and control layouts. When a magnetic field is present, the sensor provides a straightforward on/off output through its NPN interface, making it suitable for DC control circuits that require an NPN switch.
