Power supply and signal cables (inputs/outputs):
• Cable entry M20 x 1.5 (8 to 12 mm / 0.31 to 0.47 inch)
• 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 / 0.31 to 0.47 inch)
• 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 HistoROM T-DAT saves measuring system data if power supply fails.
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter,
serial number, calibration factor, zero point, etc.)
No measures necessary.
