That speed suits it for high-speed part-present detection or profiling on a conveyor — at 12 m range, it can see across a wide aisle or into a deep bin. The 2 x push-pull output configures as NPN or PNP (selectable), which simplifies integration with either sinking or sourcing PLC inputs without a level-shifter. Power is 12–30 VDC, so it runs off a standard 24 VDC panel supply. The M12 5-pin male connector (standard A-coded) mates with common quick-disconnect cables; no hardwiring into the sensor head, which speeds replacement on a line. IP65/IP67 means it handles washdown and dust — suitable for food, beverage, or automotive body shops where hosing is routine. Dimensions: 32 mm wide, 59 mm high, 43 mm deep. The 32 mm width is the critical panel-fit dimension — it matches the standard 30–35 mm slot in most sensor-mount brackets (e.g., the Banner SMB-series). The 59 mm height means it clears a standard 80 mm profile rail or machine frame. Mounting holes are on the rear face; no side-mount adapter needed for a typical bracket. ## Output and wiring considerations The 2 x push-pull output is a single output channel but dual-polarity — it sources current when the PNP side is active and sinks when the NPN side is active. For a commissioning engineer: wire pin 4 (BN) to the load common, and pin 2 (WH) to the PLC input. The M12 pinout follows the standard 5-pin A-coded assignment (1: BN +VDC, 2: WH output, 3: BU 0 VDC, 4: BK output, 5: GY not used). No special termination required beyond a shielded cable if running near VFDs.","metaTitle":"Banner DS35-B15521 Dx35 Red Laser Distance Sensor, 12 m","metaDescription":"Banner DS35-B15521 Dx35 distance sensor, red laser, 50 mm to 12 m range, 4.5 ms response, IP65/IP67, M12 connector.

The 12 m range is the maximum under ideal conditions (90% reflective target); real-world range on a dark or angled surface will be shorter, but the 50 mm minimum means it can detect objects very close to the lens without a blind zone."},{"question":"What output types does the DS35-B15521 support?","answer":"It has a 2 x push-pull output configurable as NPN or PNP.
