1045629

Overview

The SICK IQ40-20BPSKC0K is a proximity sensor with a rectangular housing and short construction. It features an M12, 4-pin connector for connection and operates as a PNP normally closed output in a DC 3-wire configuration. The sensing distance (Sn) is 20 mm, with a guaranteed switching distance (Sa) of 16.2 mm. The unit supports flush mounting in metal and has a switching frequency of 100 Hz. Dimensions are 40 mm x 40 mm x 66 mm. Protection class is IP67 according to EN60529.

Feature Summary

• Compact rectangular design suitable for space-constrained installations
• Robust metal-flush mounting capability for industrial environments
• Integrated M12 connector interface for secure electrical connection

Applications

• Automated assembly line positioning
• Packaging machine object detection
• Industrial robot end-effector presence verification

Procurement Notes

Verify the specific ordering suffix against the official SICK datasheet to confirm the exact cable length, connector type, and material specifications. Ensure the voltage rating matches the control system requirements. Confirm that the PNP NC output logic aligns with the PLC input configuration before finalizing the purchase order.

Selection Notes

Select this model when a 20 mm sensing range is required in a compact form factor. The IP67 rating ensures suitability for harsh industrial conditions. Verify compatibility with existing M12 wiring infrastructure. Consider the 100 Hz switching frequency limit for high-speed applications.

Part Context

This component belongs to the SICK IQ standard series, designed for reliable proximity detection in automation tasks. The IQ series emphasizes modular design and ease of integration into various industrial control systems, providing consistent performance across different application scenarios.

Replacement Considerations

Consult the official SICK replacement guide for direct equivalents. Verify pinout compatibility and mechanical dimensions if substituting with other brands. Ensure the replacement maintains the same PNP NC output function and IP67 protection level.
