SICK Fotoelektrický snímač, řada: W12-3 LED Blok 4kolíkový, výstup: PnP Retroreflexní IP66, IP67, IP69K

SICK W12-3 Series Photoelectric Sensor, IP66/IP67/IP69K, 330μs Response Time - WL12-3P2431

This photoelectric sensor is a Compact retroreflective LED detector designed for industrial automation and control environments. It operates on a wide DC supply range and uses autocollimation to detect objects against a reflector, offering a small rectangular form suited to panel mounting and integration where space is limited.

Features & Benefits

• 10V–30V DC supply for flexible system integration
  Response time 330μs enabling high-speed detection
  PNP complementary output supporting common PLC inputs
  IP66 IP67 IP69K metal housing for harsh environments
  Visible red LED light source with 100,000h average life
  4-pin M12 connection for secure, serviceable wiring

**Applications**

• Suitable for conveyor object detection using a reflector
  Ideal for machine safety presence-sensing
  Used with PLCs in packaging automation lines
  Can be used for high-pressure washdown production areas
  Suitable for panel-mounted sensing in Compact assemblies

What is the typical sensing reach with standard reflector types?

With a common rectangular reflector the device detects targets up to 5m typically and can reach 7m under optimal reflector conditions.

How does the sensor indicate operating status and signal reception?

Two indicators are provided: one green LED for supply presence and one yellow LED to show received light beam status.

How is sensitivity adjusted on-site?

A five-turn potentiometer is fitted to permit fine sensitivity tuning for differing reflector materials and distances.

What electrical protections are incorporated?

The input is reverse-polarity protected and the outputs include overcurrent and short-circuit protection along with interference suppression features.

Which temperature range can it operate within?

The unit functions across −40°C to +60°C ambient temperatures suitable for varied industrial climates.

Notes

For retro-reflective sensors a suitable reflector is required.
