4125917

Overview

The SICK part number 4125917 corresponds to the IQ40-20BPSKC0K, a proximity sensor from the IQ40 series. It features a rectangular housing with dimensions of 40 mm x 40 mm x 66 mm and utilizes an M12 connector for connection. The device operates as a PNP switching output with a normally closed function, designed for DC 3-wire electrical execution. It provides a sensing range (Sn) of 20 mm and a safe sensing range (Sa) of 16.2 mm. The unit supports a switching frequency of 100 Hz and carries an IP67 enclosure rating.

Feature Summary

• Features a compact rectangular housing design suitable for flush installation in metal surfaces.
• Equipped with a rotatable M12 connector allowing for flexible cable routing.
• Provides reliable detection through defined safe sensing range parameters.

Applications

• Automated assembly line positioning
• Packaging machine object detection
• Industrial safety gate monitoring

Procurement Notes

Verify the specific suffix code KC0K against the official datasheet to confirm the exact connector type and switching function. Ensure the application environment meets the IP67 protection requirements and that the power supply matches the DC 3-wire PNP specifications. Cross-reference the mechanical dimensions with the installation space constraints before procurement.

Selection Notes

Select this model when a short-batch rectangular form factor is required for tight mounting spaces. The PNP output and M12 interface are standard for modern PLC integration. Consider the 100 Hz switching frequency limit for high-speed applications and ensure the 20 mm sensing distance aligns with the target object requirements.

Part Context
