Square D PJH311P Cylindrical Proximity Switch Sensor

Square D PJH311P Cylindrical Proximity Switch Sensor is a 30 mm diameter cylindrical proximity switch from Square D (Schneider Electric) designed for non-contact sensing in industrial automation. The PJH311P designation identifies it as a 30 mm cylindrical sensor within the Square D 9006 family, a compact style commonly used for panel- or machine-mounted sensing in control circuits. This sensor provides a discrete electrical signal in response to the approach of a target, enabling automatic triggering of equipment and position or presence sensing on manufacturing lines. While exact electrical characteristics can vary by configuration in the 9006 family, listings consistently describe PJH311P as a 30 mm cylindrical proximity switch suitable for integration into standard Square D control architectures, offering a robust form factor for demanding environments. Typical implementation scenarios include assembly lines, material handling, conveyors, and machine tooling where reliable, contactless detection is required.
