SMC Corporation ZSE5B-02-27L Pneumatic Solenoid Valve

SMC ZSE5B-02-27L is a compact pressure switch in SMC’s ZSE5B family that monitors pneumatic pressure and outputs a switch signal when the preset threshold is reached. It operates from a 12–24 VDC supply and uses a three‑wire connection: Brown for DC+, Blue for DC−, and Black for the switch output (NPN open‑collector, 27 type). The sensor detects pressures in the range of -100 kPa to +100 kPa (approximately -0.98 to +0.98 bar), enabling crisp electrical signaling as soon as the setpoint is crossed. The ZSE5B‑02‑27L body is molded in PBT with vinyl‑coated lead wires, designed for integration into standard SMC pneumatic installations and manifolds. This device is intended for automation and control applications that require a reliable electrical signal triggered by crossing a defined pneumatic pressure, such as pressure monitoring in tooling, process interlocks, and feedback signaling in automated lines. The “-02‑27L” designation identifies the specific model variant within the ZSE5B series, and proper operation relies on following SMC’s mounting and electrical connection guidelines to ensure consistent switching performance.
