Description
EH-303A KEYENCE Proximity switch NEWProduct Description:
Long-distance Separate-amplifier Proximity Sensors
Detecting distance twice that of conventional sensors
Detecting distance is easily adjustable
Wide range of sensor head types available.
Built-in alarm output
Long Detecting Distance
A separate amplifier gives the ES series twice the detecting distance of self-contained proximity sensors.
Easily Adjustable Detecting Distance
The ES series doesn't need precise adjustments to sensor position during setup. You can adjust the detecting distance using the adjustment trimmer after the sensor head is installed or during operation. Because of its small amount of hysteresis, the ES series can detect minute height differences of continuously moving objects.
[NEW] ES01 Series Amplifier
25-turn metal trimmer for time adjustment. No need to bother with minute position adjustments of sensor heads during installation or maintenance.
17 Models of Sensor Heads are Available
Sensor heads are available in sizes ranging from 2.8 mm to 90.0 mm in diameter.
Protected cable (EH-305S/308S/110S)
The sensor cable is encased in a stainless steel spiral tube to prevent breakage.
Compact size (EH-402)
The smallest ES series proximity sensor, with a sensor head 2.8 mm in diameter, offers a maximum detecting distance of 7 mm.
Space-saving (EH-605)
The ES series thin-type sensor is only 3.5 mm thick, enabling it to be installed in areas of limited space.
Resistant to Welding Spatter (optional)
The fluoro-polymer resin cap protects the sensor head (EH-308/110/114) from welding spatters.
Oil-resistant (EH-108)
Precision-machined stainless steel and a special sealing mechanism makes the EH-108 highly resistant to oil.
