E2EC-M/-Q, Omron-Stainless Steel Sensing Surface Amplifier Proximity Sensor

 

Features

• Sensing Surface has 10 times the strength against wear, compared to previous models
• Sensing head is 18 mm in length. Ideal for use embedded in devices.
• Prevents adherence of weld spatter to the Sensing Head. (Improved spatter-resistant model)
• Employs a fluoride cable (Improved spatter-resistant model)
