SICK Background Suppression Distance Sensor, Block Sensor

SICK Dx35 Series Distance Sensor, Background Suppression Detection Type, IP65, IP67 - DS35-B15821

This distance sensor detects objects using a focused laser beam and suppresses background reflections for reliable presence measurement in industrial environments. Housed in robust plastics and acrylic, it is designed for panel installation and interfaces digitally to control systems, offering adaptable NPN or PNP output configurations for integration with automation equipment.

Features & Benefits

• Laser light source delivers precise detection and repeatable readings
  IP65/IP67 protection enables use in dusty and wet settings
  Temperature range -30 to 55°C permits operation in varied climates
  5-pin M12 Terminal simplifies secure field wiring
  30V operation with 100mA current capability suits low-voltage control loops
  Response time 2.5–96.5ms supports fast cycle and slow-monitoring tasks

**Applications**

• Suitable for conveyor object detection where background suppression is required
  Ideal for pick-and-place verification in automated assembly lines
  Used with PLCs in machine control that accept NPN PNP signals
  Can be used for level sensing where a Compact Block sensor is needed
  Used for robotic end-of-arm presence checks on panel-mounted installations

What materials make up the exterior and how do they affect mounting?

The outer construction combines ABS, polycarbonate and acrylic components to provide a balance of impact resistance and optical clarity while remaining compatible with panel-mount fittings.

How does the Interface support integration with control systems?

A digital Interface with selectable NPN or PNP output logic connects via a 5-pin M12 terminal, enabling direct linkage to common PLC and relay inputs.

What environmental protections does it offer for harsh sites?

The unit meets IP65 and IP67 ratings, affording protection against dust ingress and temporary immersion, suitable for challenging production floors.

Are there approvals relevant to international deployment?

It conforms to recognised standards and approvals including EU, UK and cULus listings, Plus China RoHS and ACMA certifications.
