Optimize your ultra-low fluidic layouts and sensitive pneumatic controls with the authentic 26PCAFA6D miniature pressure sensor. This board-level active sensor is specifically calibrated to measure low-range differential pressures with exceptional linearity. Utilizing an advanced micro-machined Wheatstone bridge, it translates micro-pressures into a stable, unamplified millivolt analog voltage. Its 4-SIP through-hole configuration ensures rigid PCB mounting and reliable electrical termination, while the specialized wet/wet media compatibility allows safe, bi-directional contact with non-corrosive gases and dry air on both ports.
