85 to 260 V AC, 45 to 65 Hz
20 to 55 V AC, 45 to 65 Hz
16 to 62 V DC
Power supply and signal cables (inputs/outputs):
• Cable entry M20 x 1.5 (8 to 12 mm)
• Sensor cable entry for armored cables M20 x 1.5 (9.5 to 16 mm)
• Threads for cable entries, 1/2" NPT, G 1/2"
Connecting cable for remote version:
• Cable entry M20 x 1.5 (8 to 12 mm)
• Sensor cable entry for armored cables M20 x 1.5 (9.5 to 16 mm)
• Threads for cable entries, 1/2" NPT, G 1/2"

AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current:
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Lasting min. 1 power cycle
• EEPROM or T-DAT saves measuring system data if power supply fails
• S-DAT: exchangeable data storage device which stores the data of the sensor (nominal diameter,
serial number, calibration factor, zero point, etc.)
