S18U Speciﬁcations

Effective Beam

See Charts EBPC-1 and EBPC-2 on page 316.

Supply Voltage and Current 10 to 30V dc (10% max. ripple); 65 mA max. (exclusive of load), 40 mA typical @ 25V input

Ultrasonic Frequency 300 kHz, rep. rate 2.5 milliseconds

Supply Protection Circuitry Protected against reverse polarity and transient voltages

Output Protection Protected against short circuit conditions

Output Ratings

Analog:

Analog Voltage Output: 2.5 kΩ min. load resistance

Minimum supply for a full 10V output is 12V dc (for supply voltages

between 10 and 12, V out max is at least V supply -2)

Analog Current Output: 1 kΩ max @ 24V input

Max load resistance = (Vcc-4)/0.02 Ω

Discrete: 100 mA max.

OFF-state leakage current: less than 5 µA

NPN saturation: less than 200 mV @ 10 mA and less than 600 mV @ 100 mA

PNP saturation: less than 1.2V @ 10 mA and less than 1.6V @ 100 mA

Output Conﬁguration

Analog: 0 to 10V dc or 4 to 20 mA, depending on model

Discrete: Bipolar: One NPN (current sinking) and one PNP (current sourcing) output in each model. Solid-state switch conducts

when target is sensed within sensing window.

Output Response Time

Analog: 30 milliseconds: Black wire at 0-2V dc (or open) Discrete: 5 milliseconds

2.5 milliseconds: Black wire at 5-30V dc

Delay at Power-up

300 milliseconds

Linearity*

(Analog output models)

2.5 milliseconds response: ± 1 mm

30 milliseconds response: ± 0.5 mm

Resolution*

(Analog output models)

2.5 milliseconds response: 1 mm

30 milliseconds response: 0.5 mm

Repeatability

(Discrete models)

0.5 mm

Temperature Effect

0.02% of distance/ ° C

Temperature Warmup Drift

Less than 1.7% of sensing distance upon power-up

Minimum Window Size

5 mm

Switching Hysteresis

(Discrete output models)

0.7 mm

Adjustments

Sensing window limits: TEACH-Mode programming of near and far window limits may be set using the push-button or remotely

using TEACH input.

Indicators

Power/Signal Strength (Red/Green)

Green—Target is within sensing range

Red—Target is outside sensing range

OFF—Sensing power is OFF

TEACH/Output Indicator (Yellow/Red)

Yellow —Target is within taught limits

OFF—Target is outside taught window limits

Red—Sensor is in TEACH mode

Remote TEACH Input

Impedance: 12 kΩ

Construction

Threaded Barrel: Thermoplastic polyester Push-Button Housing: ABS/PC

Push Button: Santoprene Lightpipes: Acrylic

Environmental Rating

Leakproof design is rated IEC IP67; NEMA 6P

Connections

2 m or 9 m shielded 5-conductor (with drain) PVC jacketed attached cable, or 5-pin Euro-style quick-disconnect. QD cordsets are

ordered separately. See page 316.

Operating Conditions

Temperature: -20° to +60° C Relative humidity: 100%
