Specifications
Unless otherwise noted, the following
specifications are for a proximity transducer
system b18

with a -24 Vdc power supply, a 10 k
Ω
load, an AISI
4140 steel target, and a probe gapped at 1.27mm
(50 mils).
Electrical
XL Proximitor Sensor Input
Accepts one noncontacting 3300 5mm Proximity
Probe and XL Extension Cable.
Power
Requires -17.5 Vdc to -26 Vdc at 12 mA maximum
consumption. Operation at a more positive
voltage than -23.5 Vdc can result in reduced linear
range.
Supply Sensitivity
Less than 2 mV change in output voltage per volt
change in input voltage.

Note:
Outer conductor refers to the shielded conductor that is
attached to the connector, not the armor braid.
Extension cable capacitance
69.9 pF/m (21.3 pF/ft) typical.
Field Wiring
Recommend using 3-conductor shielded triad
cable 0.2mm to 1.5mm (16 AWG to 24 AWG). 305
metres (1,000 feet) maximum length between 3300
XL Proximity Transducer and monitor. Consult
