7.2 Opposed-Mode Models: Specifications
Supply Voltage and Current
10 V dc to 30 V dc (10% maximum ripple within specified limits) at 30
mA
Power and Current Consumption, exclusive of load
Normal Run Mode: 1.2W, Current consumption < 50 mA at 24 V dc
Supply Protection Circuitry
Protected against reverse polarity and transient overvoltages
Output Protection Circuitry
Protected against false pulse on power-up and continuous overload or
short-circuit of output
Output Configuration
Channel 1: IO-Link, Push/pull output, configurable PNP or NPN output
Channel 2: Multi-function remote input/output, configurable PNP or
NPN
Power Up Delay
Momentary delay on power-up, < 1.5 s, output does not conduct during
this time
Gain
The gain setting can be changed via IO-Link
Gain values are: Auto and the fixed modes High, Mid, and Low
Response Time and Response Repeatability
When gain = Auto, the receiver optimizes the gain during Run mode for
the current condition.
When gain = Fixed, the receiver optimizes the power for the presented
configured condition(s).

Emitter Power
High Power is Power 5.
Low Power is Power 0.
The following power levels are available via IO-Link to set intermediate
power levels when looking for good contrast control with separation
distances > 4 m: Power 5, Power 4, Power 3, Power 2, Power 1, and
Power 0
Emitter LED
EV model: Visible red, 625 nm
E models: Infrared, 940 nm
Indicators
Two LEDs (1 green, 1 amber)
Green On: Indicates power applied and sensor ready
Green Flashing: Indicates sensor operating in marginal state, in need of
reconfiguration
Amber On: Indicates output conducting
