SICK CQ35-25NPP-KW1 Rectangular Capacitive Proximity Sensor CQ 25 mm PNP 200mA 36V dc 250 V ac 36 V

SICK Series CQ Proximity Sensor, 25mm Maximum Detection, IP67 - CQ35-25NPP-KW1

This proximity sensor is a Compact rectangular device designed to detect metallic and non-metallic objects in industrial automation settings. It operates from a DC supply and delivers a PNP switching output, suited to integration with control systems where non-contact object presence detection is required. The sensor’s construction utilises polycarbonate-based plastic to provide a sealed housing for use in environments where ingress protection is necessary.

Features and Benefits:

• Non-flush mounting simplifies installation in offset positions
  PNP output provides straightforward sourcing Interface for controllers
  Pre-cabled termination reduces wiring time on-site
  25mm detection range enables close-proximity sensing tasks
  36V DC maximum supply allows operation from common control voltages
  200 mA switching current supports direct drive of modest loads

Applications

• Suitable for part detection on assembly conveyors where close-range sensing is required
  Ideal for presence monitoring of mixed-material components on pick-and-place stations
  Used with PLC inputs in machine safety interlock arrangements on factory lines
  Can be used for object counting in packaging operations with limited space
  Used for end-of-travel detection on pneumatic actuators in automation cells

What temperature extremes can it withstand during operation?

It is rated to operate between -25 °C and 75 °C for functionality across typical plant environments.

How robust is the enclosure to dust and water exposure?

The housing meets IP67 protection, providing full dust ingress prevention and temporary immersion resistance.

What electrical switching frequency can be expected for Rapid detection tasks?

The device supports switching up to 50 Hz, allowing use in moderate-speed sensing applications.

Which standards has it been evaluated against for industrial acceptance?

It holds UL and CE approvals indicating assessment to relevant safety and conformity criteria.
