The DPSN1 / DPSP1 digital pressure switch delivers precise vacuum and pressure detection for non-corrosive gases. Its two-color (red/green) dual-row LCD shows the live measured value and the setpoint at the same time, so operators can monitor and adjust the unit at a glance. With two independent switching outputs, three output modes and a wide choice of delay and response times, it integrates easily into vacuum grippers, pick-and-place cells and other automation built around Fairino cobots.
The switch is available with NPN output (DPSN1) or PNP output (DPSP1), and in two pressure ranges: a compound vacuum range of −100 to 100 kPa (-01) or an extended range of −100 to 1,000 kPa (-10).
