Overview
The Keyence AP-43 is a digital pressure sensor head designed for positive gauge pressure measurement up to 1 MPa (145 PSI). Engineered for seamless integration with Keyence’s AP-C40 (2-Color Digital Display) and AP-V40 (Wire-Saving AI Digital Sensor) series, the AP-43 provides accurate, reliable pressure detection for factory automation, assembly line monitoring, and industrial control processes. The sensor features an M5 male threaded pressure port for direct connection to pneumatic and fluid systems.
