SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK ZoneControl Series Photoelectric Sensor, Background Suppression Detection Type, IP67 - RT-P3221

This photoelectric sensor is designed to detect objects using background suppression in industrial automation settings. It operates with an LED light source and connects via a 4-pin M12 Interface for straightforward integration into control systems. The device is built in a Compact Block form with a plastic enclosure and meets IEC68 environmental standards for demanding production environments.

Features & Benefits

• Background suppression detection reduces false triggers from backgrounds
  PNP output enables simple sourcing logic integration
  IP67 ingress protection permits wash‑down and dusty environments
  2 MS response time supports Rapid detection cycles
  -40 to 60 °C operating range endures extreme temperature swings
  30V maximum DC rating matches common industrial control voltages

**Applications**

• Suitable for conveyor object presence detection in packaging lines
  Ideal for part orientation checks on assembly machines
  Used for height or distance discrimination in pick‑and‑place systems
  Can be used for bin or hopper level sensing where background suppression helps
  Suitable for retrofitting into machines requiring a Compact Block sensor

What connector is provided for wiring into control panels?

It uses a four‑pin M12 connector for secure, standardised field wiring.

How does the device handle dusty or wet production areas?

The enclosure achieves IP67 protection, preventing dust ingress and allowing immersion‑level resistance.

What electrical limits must be observed to avoid damage?

The sensor must not be driven above 30V DC and should be supplied within the 100 mA current capability.

Which output wiring logic does it employ for control integration?

The unit provides a PNP switching output suitable for sourcing input architectures.
