The Importance of a High-Quality Sensor Housing

A sensor housing must guarantee:

✔ Dimensional stability

Internal space accuracy determines:

• sensor alignment

• PCB positioning

• sealing integrity

• cable routing clearance

✔ Mechanical strength

The housing must withstand:

• vibration

• impact

• mounting stress

✔ Thermal & chemical resistance

Especially when used in:

• electric vehicles

• power systems

• industrial equipment

✔ Waterproofing & sealing

Critical for:

• IP67 / IP68 rating

• outdoor use

• fluid exposure

✔ Material flow & cosmetic control

No flow lines
No weld marks
No sink marks
No jetting lines
No flashing
