SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK Series W9 Photoelectric Sensor, Laser Light Source, IP66/IP67/IP69K - WTB9L-3P2261

This photoelectric sensor detects small objects using a laser-based background suppression method and is intended for industrial automation environments. It is housed in a robust plastic enclosure and connects via a 4-pin M8 interface, offering a Compact rectangular form suited to inline sensor installations where precise separation of target and background is required.

Features and Benefits:

• 500 μs response provides high-speed detection for Rapid processes
  30V DC supply supports common industrial control systems
  100 mA maximum current enables direct interfacing with many control inputs
  PNP output simplifies integration with sourcing input architectures
  IP66/IP67 protection resists dust and heavy water jets
  IP69K rating allows use in high-pressure, high-temperature washdowns

Applications

• Suitable for pick-and-place verification on conveyor lines
  Ideal for small component sorting in electronics assembly
  Used for presence detection in automated packaging stations
  Can be used for position sensing where background suppression is required

What connector type does it use for wiring?

It uses a 4-pin M8 connector that provides a compact, industry-standard plug-in connection for signal and supply lines.

How does the sensor handle harsh washdown procedures?

The enclosure meets IP69K, which permits exposure to high-pressure, high-temperature cleaning cycles commonly used in food and pharmaceutical production.

What signal polarity should my control system expect?

The sensor provides a PNP output, delivering a positive switching signal suitable for sourcing-compatible input modules.

What temperature range can it operate within?

It operates reliably from -10 °C up to 50 °C, covering typical ambient conditions found in manufacturing and workshop environments.

Are there conformity marks relevant to workplace installations?

It carries CE and UL certifications indicating conformity with applicable European and North American safety and performance standards.
