The DPSN1-01-020 is a compound-range unit covering −100 to +100 kPa with two independent NPN outputs, so one device can watch both the vacuum that holds a part and the positive blow-off that releases it.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA digital pressure switch for vacuum work. The range is compound — −100 to +100 kPa — so one unit covers both the vacuum side of a suction gripper and the low positive pressure used to blow a part off.\n\nTwo independent NPN outputs mean you can set one threshold for \"part gripped\" and a second for \"vacuum lost\", and wire them to different controller inputs. The dual-row display shows live pressure in red and your setpoint in green at the same time, which makes commissioning a suction cup array far quicker than a single-value gauge.\n\nPT1\/8 male and M5 female ports fit directly onto common ejectors and manifolds.

It is a compound range, so the same unit reads vacuum and low positive pressure. For higher positive pressure up to 1 MPa, use the DPSN1-10-020 variant instead.\u003c\/p\u003e\u003ch3\u003eWhy are there two outputs?\u003c\/h3\u003e\u003cp\u003eOUT1 and OUT2 have independent setpoints. A common setup is OUT1 as “part gripped” at a strong vacuum level and OUT2 as “vacuum low” as an early warning, wired to two different controller inputs.\u003c\/p\u003e\u003ch3\u003eIs this NPN or PNP?\u003c\/h3\u003e\u003cp\u003eThis model is NPN (sinking). The DPSP1-01-020 is the PNP (sourcing) equivalent if your input card needs that.\u003c\/p\u003e\u003ch3\u003eWhat do the five wires do?\u003c\/h3\u003e\u003cp\u003e1 brown is 12–24 V supply, 2 black is OUT1, 3 white is OUT2, 4 orange is not connected, and 5 blue is ground.\u003c\/p\u003e\u003ch3\u003eIs it compatible with AirTAC DPS switches?\u003c\/h3\u003e\u003cp\u003eYes — it follows the AirTAC DPS series model coding, port threads and electrical interface, so it can replace one in an existing installation. It is a compatible equivalent, not AirTAC-branded product.\u003c\/p\u003e\u003ch3\u003eWhat do the two display rows show?\u003c\/h3\u003e\u003cp\u003eThe red row is live pressure and the green row is the selected setpoint, shown at the same time. That makes setting thresholds on a suction cup array much faster than with a single-value gauge.\u003c\/p\u003e","brand":"Glunova Biotech","offers":[{"title":"DPSN1-01-020 + VPCT bellows suction cup set (4\/6\/8 mm)","offer_id":50824797913327,"sku":"DPSN1-01-020-NPN-CUPSET","price":103.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0821\/5406\/2063\/files\/01_0cb6abf8-c73c-457a-b35a-457f5df676bf.jpg?v=1789745408","url":"https:\/\/armdojo.com\/products\/digital-vacuum-pressure-switch-dpsn1-01-020-npn","provider":"ArmDojo","version":"1.0","type":"link"}
