Inductive proximity sensor with gold-plated pins

E2A-4

Inductive proximity sensor E2A-4 was created and tested for

applications in the harsh environment and at though vibration

conditions. Gold-plated contact pins provide increased protection

against corrosion in high humidity and vibration.

• Gold-plated contact pins

• Connector type M8 and M12 models

• PNP/NPN NO

September 2012 5:23 17 E2A-4 Mounting The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor maybe damaged or loses its waterresistance. Do not tighten the nut with excessive force. A washer must be used with the nut. 3. Check for attachment or accumulation of metal powder or dust. 4. Check for abnormal temperature conditions and other environmental conditions. 5.
