定义
A protective enclosure designed to shield sensitive pickup or sensor head components from environmental hazards, mechanical damage, and electromagnetic interference while maintaining operational integrity in industrial settings. It provides physical protection, environmental sealing, and sometimes thermal management for precision sensing equipment.
工作原理
Acts as a barrier between the sensor head and external environment, using structural design to absorb impacts, sealing mechanisms to prevent ingress of contaminants, and material properties to shield against interference while allowing necessary signal transmission through designated apertures or transparent sections.
材料
Typically made from engineering plastics (POMPEEKpolycarbonate)aluminum alloys (6061-T67075)or stainless steel (304316) with IP67/IP69K rated sealsEMI/RFI shielding coatingsand optional transparent windows using polycarbonate or borosilicate glass.
Weight
0.2-2.5kg depending on size/material
EMI Shielding
≥30dB
Mounting Type
Flange, bracket, or direct thread
Impact Resistance
IK08
Protection Rating
IP67/IP69K
Temperature Range
-40°C to +85°C
标准
ISO 13857ISO 14120DIN EN 60529IEC 61000-6-2

常见问题

What protection standards do these housings typically meet?

They typically comply with IP67/IP69K for dust/water ingress protection, IK08 for impact resistance, and IEC 61000-6-2 for electromagnetic compatibility in industrial environments.

Can protective housings affect sensor performance?

Properly designed housings maintain sensor performance through appropriate material selection, precise aperture design, and shielding that doesn't interfere with signal transmission, though calibration may be required after installation.

How are these housings mounted on machinery?

Mounting options include flange mounting with gaskets, bracket systems with vibration dampeners, or direct threading compatible with sensor specifications, often using stainless steel fasteners for corrosion resistance.
