Barksdale D1T-A150SS NSNBC01 Limit Switch Assembly

The Barksdale D1T-A150SS NSNBC01 Limit Switch Assembly is a diaphragm-style terminal-block switch designed for pressure-actuation in industrial automation. It covers a sensing range of 1.5–150 psi and uses a 1/4" NPT female connection for straightforward installation into pressure lines. The unit provides an SPDT single-setpoint output, enabling a single actuation point to drive downstream controls or safety circuits. Electrical ratings align with common industrial loads: up to 10 A at 125/250 VAC and up to 3 A at 480 VAC, suitable for signaling relays, PLC inputs, or interlock circuits without additional components. As part of Barksdale’s D1T family, this assembly combines a diaphragm sensing element with a terminal-block interface in a compact form factor for panel mounting or inline use in compressors, pumps, and process lines where reliable, repeatable pressure switching is essential. The NSNBC01 variant denotes the specific configuration within the D1T series for OEM deployments, ensuring compatibility with single-setpoint diaphragm switches that rely on a standard 1/4" NPT port and a straightforward electrical connection.
