Position Sensors

The machine control only knows what it is shown. Whether the mold has closed, where the screw is, how many bar the pressure reads — all of it comes from sensors. When one sensor reads wrong, the machine looks fault-free but the part comes out bad.

Proximity sensors confirm position, and their failures stop the machine completely, which makes them easy to notice. Pressure and temperature sensors, by contrast, can drift quietly — the machine keeps running while the reading is wrong. Comparing the value on the screen against a gauge or an independent thermometer from time to time is what catches that drift.

Is it time to replace?

• The machine waiting for a position confirmation and hanging mid-cycle
• Pressure shown on the screen not matching the gauge
• Intermittent alarms that repeat and clear on their own
• The mold protection circuit tripping for no apparent reason
• Oil or metal dust building up on the sensor face

What to send us when you order

1. The manufacturer code of the sensor and the body size (M12, M18, M30)
2. Output type: PNP / NPN, NO / NC, analog 4-20 mA or 0-10 V
3. Measuring range — for example 0-350 bar on a pressure sensor
4. Cable length and connector type
