Specifications

Specifications were determined with a -24 Vdc supply, 10 k Ω load, and a 102 mm (4 in) diameter AISI 4140 steel target at +22°C (+72°F).

Input

Accepts one noncontacting 7200 series 35 mm Proximity Probe and Extension Cable.

Power

-18 Vdc to -24 Vdc at 12 mA maximum consumption.

Output Resistance

50 Ω.

Probe DC Resistance (nominal) (RPROBE)

5.0 Ω +2.85 Ω/m (0.866 Ω/ft).

Extension Cable DC Resistance (nominal)

  • Center conductor (RCORE): 2.80 Ω/m (0.850 Ω/ft).
  • Shield conductor (RJACKET): 0.05 Ω/m (0.016 Ω/ft).

Extension Cable Capacitance

68.8 pF/m (20.9 pF/ft) typical.

Field Wiring

Recommend using three-conductor shielded triad cable. Maximum length of 305 metres (1,000 feet) between the Proximitor Sensor and the monitor. Consult the manual for frequency roll-off at longer lengths.

Linear Range

12.7 mm (500 mils). Linear range begins at approximately 1.3 mm (50 mils) from target and is from 1.3 to 14.0 mm (50 to 550 mils) (approximately -1.5 to -11.5 Vdc).

Average Scale Factor (ASF)

0.79 V/mm (20 mV/mil) ±6% including interchangeability error when measured in increments of 1.3 mm (50 mils) over the 500 mil linear range.

Deviation from Best Fit Straight Line (DSL)

Less than ±0.33 mm (±12.8 mil).

Minimum Target Size

57 mm (2.25 in) in diameter (flat target).

Electrical Classification

Complies with the European CE mark. Hazardous area approvals not available.

Mechanical

  • Probe Tip Material: Molded thermoplastic.
  • Probe Case Material: 300 series stainless steel.
