Product Description

The Keyence AP-V41A is a versatile amplifier unit designed for use with the AP-V40 series digital pressure sensors. It features a 4.5-digit, 2-color LED display with a character height of 4.5 mm, providing clear readings with a display cycle of 10 times per second. The unit offers NPN control outputs with a maximum current of 100 mA at 40 V or below, and supports both normally open (NO) and normally closed (NC) configurations. With a power supply range of 12 to 24 VDC ±10% and a ripple (P-P) of 10% or less, it ensures stable operation in various industrial environments. The AP-V41A is equipped with features like zero-shift input, analog output (1 to 5 V), and a chattering prevention function with selectable response times. Its robust design includes a polycarbonate housing and is suitable for use in ambient temperatures ranging from 0 to +50°C with a relative humidity of 35 to 85% RH (non-condensing). The unit also complies with UL and CSA standards, ensuring reliability and safety in industrial applications.
