Product Description

The Keyence AP-53ZA is a compact digital pressure sensor designed for precise measurement of positive gauge pressure in industrial applications. It features a 4-digit, 7-segment LED display with a character height of 8 mm, providing clear and easy-to-read pressure readings. The sensor offers a fast response time of 5 ms and a repeatability of ±0.5% of full scale ±1 digit or less, ensuring accurate and reliable measurements. With its NPN open-collector output, zero-shift input, and selectable output modes, the AP-53ZA is suitable for integration into automated systems requiring precise pressure monitoring and control.​
