KEYENCE proximity sensors I (EM / EH / ES series)
This group of KEYENCE proximity sensor spare parts covers EM series embedded units, EH series sensor heads with separate amplifiers and the ES series sensor head, used for detecting the position of metal objects in automated equipment, precision machinery and high-speed lines. The models are IP67 rated with a wide ambient temperature range for stable operation in oily, dusty or humid environments.
Main models
| Model | Type / mounting | Sensing distance | Output / features |
|---|---|---|---|
| EM-005 | Main unit, embedded, M5 thread | 1.0 mm ±15% | NPN, IP67, 1.2 kHz response |
| EM-054 | Main unit, ø5.4 mm cylindrical, embedded | 1.2 mm ±10% | NPN, −25 to +80°C, 1.2 kHz |
| EH-910 | EH series sensor head, ø10 mm cylindrical | Separate-amplifier type | NPN / PNP selectable, multiple heads in parallel |
| EH-305 | EH series sensor head, ø3 mm cylindrical | 0.6 mm ±15% | Stainless steel housing, IP67, ultra-compact |
| ES-X38 | ES series sensor head, ø3.8 mm | 0.8 mm ±15% | Flexible cable for tight spaces |
Selection tips
- EM series: for installation inside space-limited precision equipment.
- EH series: the separate-amplifier design lets the sensor head reach into harsh environments while the amplifier circuit stays protected.
- ES series: for extremely narrow mounting spaces.
