1112945

Overview

The SICK part number 1112945 corresponds to the MZT7-03VPS-KRD, a photoelectric retro-reflective sensor from the MZT7 series. It features a PNP normally open switching output and is designed for DC 3-wire operation. The device utilizes an M8 connector with three pins and includes a knurled nut for secure mounting. It has a sensing range of 10 mm and is constructed with a PUR cable jacket rated for IP65 and IP67 protection levels. The unit supports operating temperatures up to 80 °C and weighs approximately 0.05 kg.

Feature Summary

• Compact rectangular housing design suitable for space-constrained installations
• Integrated M8 connector with knurled nut for reliable mechanical fixation
• High thermal resistance allowing operation in elevated temperature environments
• Robust PUR cable construction providing resistance to oils and mechanical stress

Applications

• Automated assembly machinery requiring precise short-range object detection
• Packaging equipment operating in high-temperature processing zones
• Material handling systems utilizing retro-reflective detection methods
• Industrial automation cells demanding compact form factor sensors

Procurement Notes

Verify that the specific order matches part number 1112945 to ensure receipt of the MZT7-03VPS-KRD variant with the M8 connector and knurled nut. Confirm compatibility with existing control system voltage requirements and switching logic. Check environmental specifications against installation site conditions, particularly regarding temperature limits and ingress protection needs. Ensure proper accessories are sourced if extension cables or additional connectors are required for the final setup.

Selection Notes

Select this model when a compact retro-reflective sensor with a fixed 10 mm range is required. The M8 connector option simplifies wiring compared to cable-only versions. Consider the 80 °C rating for applications near heat sources where standard plastic housings might fail. The PNP NO output is standard for many PLC inputs. Evaluate the need for the knurled nut feature if vibration resistance during mounting is a priority over smooth surface aesthetics.

Part Context

This component belongs to the MZT7 series of photoelectric sensors by SICK. The series focuses on compact solutions for general industrial automation tasks. The MZT7 line offers various configurations including different cable lengths, connector types, and switching outputs to suit diverse mounting and electrical interface requirements within automated production environments.

Replacement Considerations

Direct replacements must match the MZT7-03VPS-KRD specification exactly. Verify that any substitute maintains the 10 mm sensing range, PNP NO output, and M8 connector interface. Ensure the replacement unit meets the same IP65/IP67 ratings and 80 °C temperature tolerance. Cross-reference part numbers carefully as minor suffix changes indicate different cable lengths or connector styles.
