SICK Retroreflective Photoelectric Sensor, Block Sensor, 150 mm → 10 m, PNP, IP66, IP67, IP69K

SICK W11-2 Series Photoelectric Sensor, IP66,IP67,IP69K, 2.5ms Response Time - WL11-2P2430

This photoelectric sensor is a Compact retro‑reflective detector designed for industrial automation environments. It monitors object presence using a visible red LED beam and is suited to panel‑mount installations where a Compact footprint and dependable sensing over short to medium ranges are required.

Features & Benefits

• PNP switching output enables simple wiring into control systems
  Response time 2.5ms supports fast detection and high cycle rates
  Operating range 0.15m to 8m permits versatile placement with common reflectors
  Supply 10V–30V DC with 30mA consumption minimises power draw
  IP66, IP67, IP69K enclosure rating allows wash‑down and harsh conditions
  4‑pin M12 connector provides secure quick‑disconnect connectivity

**Applications**

• Suitable for conveyor presence detection in assembly lines
  Ideal for package sorting where Rapid switching is needed
  Used with reflective tape or small reflectors for object edge sensing
  Can be used for application of safety interlocks in machinery panels
  Used for position sensing on robotic end‑of‑arm tooling

What light source does it use and how long does it last?

It employs a visible red LED with an average service life of approximately 100,000 h at 25°C.

How is the output behaviour configured electrically?

The sensor provides complementary PNP switching with HIGH at Uv−2.5V and LOW near 0V, and an output current capability up to 100mA.

What protection is incorporated for electrical disturbances?

The device includes reverse‑polarity protection on supply connections, interference suppression, and output overcurrent/short‑circuit protection.

What environmental temperature limits apply for operation and storage?

It operates between −30°C to +60°C and may be stored between −40°C to +75°C.

What mechanical materials should users expect for mounting and optics?

The housing is manufactured from ABS plastic while the optical elements are MADE from PMMA.

Notes

For retro-reflective sensors a suitable reflector is required.
For PL80A, PL30A & C110 reflectors see stock nos. 265-2776, 265-2760 & 265-2748 respectively.
