See Chart EPBC-7 to EPBC-11 on page 327.

Sensing Range

“A” sufﬁx models: 150 mm min. near limit; 1 m max. far limit

“B” sufﬁx models: 300 mm min. near limit; 2 m max. far limit

“-CRFV” models: 300 mm min. near limit; 1.5 m max. far limit

Supply Voltage and Current

Current sourcing analog output models: 12 to 24V dc (10% max. ripple); 90 mA (exclusive of load)

Voltage sourcing analog output models: 15 to 24V dc (10% max. ripple); 90 mA (exclusive of load)

Dual-discrete output models: 12 to 24V dc (10% max. ripple); 90 mA (exclusive of load)

Ultrasonic Frequency

Short Range: 228 kHz

Long Range: 128 kHz

Supply Protection Circuitry

Protected against reverse polarity and transient voltages.

Output Protection

Protected against continuous overload and short-circuit; transient over-voltage; no false pulse on power-up.

Output Conﬁguration

Discrete (switched) output: Solid-state switch conducts when target is sensed within sensing window;

choose NPN (current sinking) or PNP (current sourcing) models.

Analog output: Choose 0 to 10V dc sourcing or 4 to 20 mA sourcing output models; output slope may be

selected using TEACH sequence.

Output Ratings

Discrete (switched) output: 100 mA max., total–both outputs

OFF-state leakage current: less than 10 µA

ON-state saturation voltage: less than 1V at 10 mA and less than 1.5V at 100 mA

Analog Output:

Voltage sourcing: 0 to 10V dc (at 1 kΩ min. resistance)

Current sourcing: 4 to 20 mA, 1 Ω to Rmax.

Rmax = V

supply

- 7V

20 mA

Output Response Time

Discrete output: “A” sufﬁx models: 48 milliseconds

“B” sufﬁx models: 96 milliseconds

Analog output: “A” sufﬁx models: 48 milliseconds average, 16-millisecond update

“B” sufﬁx models: 96 milliseconds average, 32-millisecond update

Sensing Performance

(Specied using a 100 x 100 mm

aluminum target at 25˚ C under

xed sensing conditions.)

Analog sensing resolution or discrete output repeatability: ±0.25% of measured distance

“A” sufﬁx models: .5 mm min

“B” sufﬁx models: 1 mm min

Analog linearity: ±0.5% of full-scale span

Min. window size: 10 mm

Hysteresis of discrete output: 2.5 mm

Temperature effect: 0.2% of sensing distance per ° C

Adjustments

Sensing window limits (analog or discrete): TEACH-mode programming of near and far window limits may be set using membrane

push buttons on sensor or remotely using TEACH input. Window limits may be programmed separately, or together.

Analog output slope: the rst limit taught is assigned to the minimum output value (4 mA or 0V).

Indicators

Four status LEDs: In RUN mode:

Green ON Steady: Power ON, RUN mode

Green Flashing: Discrete output is overloaded

Red Flashing: Relative received signal strength

Yellow analog ON Steady: Target is inside window limits

Yellow discrete ON Steady: Output conducting

In Program mode:

Green OFF: PROGRAM mode

Red Flashing: Relative received signal strength

Yellow ON Steady: Ready for rst window limit

Yellow Flashing: Ready for second limit

Yellow OFF: Not teaching this output

Construction

Molded reinforced thermoplastic polyester housing.

Environmental Rating

Leakproof design is rated IEC IP67; NEMA 6P

Connections

2 m or 9 m 5-conductor PVC-covered attached cable, or 5-pin Euro-style quick-disconnect tting.

QD cordsets are ordered separately. See page 325.

Operating Conditions

Temperature: -20° to +70° C Relative humidity: 100%
