SICK Retroreflective Photoelectric Sensor, Block Sensor, 15 m, Relay, IP66, IP67

SICK W280-2 Series Photoelectric Sensor, IP66, IP67, 15ms Response Time - WL280-2H4331

This photoelectric sensor detects objects using a retroreflective optical principle and is designed for industrial automation contexts. It operates with LED illumination and provides a relay-style switching output suitable for control systems. The unit is constructed with an ABS enclosure and includes a cable gland for secure electrical connection, making it applicable to factory-floor sensing tasks.

Features & Benefits

• Relay output supports switching loads up to 3A, practical for control circuits
  Rated for up to 240V AC or DC, enabling direct integration with mains systems
  Ingress protection to IP66 and IP67, permitting washdown and dust-prone areas
  Response time of 15ms, enabling Rapid detection in motion applications
  Operates from -25 to 55°C for reliable performance across temperature ranges
  Complies with EN 61000-6-3 and EN 60947-5-2, meeting electromagnetic and safety norms

**Applications**

• Suitable for conveyor object presence detection in packaging lines
  Ideal for material handling systems requiring non-contact sensing
  Used for access-control monitoring where a reflector can be mounted
  Can be used for machine safety interlocks employing relay switching

What type of termination does the sensor provide for wiring?

The device uses a cable gland termination that secures and protects the supply and output conductors at the enclosure entry.

How does the unit cope with electrical noise in industrial sites?

It is manufactured to meet EN 61000-6-3 standards which address emissions and immunity relevant to industrial electromagnetic environments.

Which light source is used and what operational advantage does it give?

An LED light source provides stable illumination with low power consumption and consistent detection characteristics.

What switching behaviour can be expected from the output?

The sensor employs a relay-style output enabling isolated, high-current switching up to 3A for external loads.
