Frequently asked questions
What is the sensing range of the DS35-B15521?
Minimum 50 mm, maximum 12 m. 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.
What output types does the DS35-B15521 support?
It has a 2 x push-pull output configurable as NPN or PNP. This means it can interface with both sinking (NPN) and sourcing (PNP) PLC inputs without an external converter.
What is the response time of the DS35-B15521?
4.5 ms. At that speed, it can detect objects moving at up to 2.6 m/s if the object is 12 mm wide — fast enough for most conveyor and packaging applications.
Integrator's note on the DS35-B15521
The DS35-B15521 is a Dx35-series red laser distance sensor from Banner Engineering, rated for 50 mm to 12 m sensing distance with a 4.5 ms response time. 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.
