SICK Background Suppression Photoelectric Sensor

SICK SureSense Series Photoelectric Sensor, IP67/IP69K, 0.5ms Response Time - HTB18-P4A2BB

This photoelectric sensor is a Compact background suppression device designed for industrial detection tasks in automation and control systems. Housed in Vistal plastic with high ingress protection, it uses a pin‑point LED to detect targets while operating across a wide ambient temperature range. Termination is via a standard 4‑pin M12 connector and it employs a PNP output for integration with common industrial controllers.

Features and Benefits:

• 0.5 MS response boosts cycle‑time performance in high‑speed systeMS
  Operates from -40°C to +65°C for harsh‑environment deployment
  IP67 IP69K enclosure allows wash‑down and dust‑tight applications
  30V DC rating supports typical control‑voltage architectures
  100 mA maximum current enables direct sensor‑driven switching
  Background suppression improves target detection near backgrounds

Applications

• Suitable for part‑present sensing on high‑speed conveyors
  Ideal for detecting small components in pick‑and‑place cells
  Used for level detection in Compact containers and bins
  Can be used for machine‑guard monitoring where wash‑down occurs

How is the sensor connected to control equipment?

It uses a four‑pin M12 Terminal allowing secure electrical connection to PLC inputs or distribution cabling.

What output polarity should my controller expect?

The device provides a PNP switching output compatible with positive‑sourcing input circuits.

Can the sensor withstand direct wash‑down cleaning?

The enclosure meets IP67 and IP69K ratings, enabling resistance to high‑pressure, high‑temperature cleaning processes.

What optical source ensures precise detection of small targets?

A pin‑point LED emitter produces a focused beam suitable for accurate background‑suppression sensing.
