Optimize your ultra-low fluidic layouts and sensitive pneumatic controls with the authentic 26PCAFA6G miniature pressure sensor. This board-level active sensor is specifically calibrated to measure positive gauge pressure relative to atmospheric ambient conditions. Utilizing an advanced micro-machined Wheatstone bridge, it translates micro-pressures into a highly linear, unamplified millivolt analog voltage. Its 4-SIP through-hole configuration ensures rigid PCB mounting and reliable electrical termination, while the specialized internal elastomer backing provides excellent media compatibility for non-corrosive gases and dry air.
