LT3 Speciﬁcations

Output Response Time

Discrete output

Fast: 1 millisecond ON/OFF Medium: 10 milliseconds ON/OFF Slow: 100 milliseconds ON/OFF

Diffuse Analog Voltage output (-3 dB)

Fast: 450 Hz (1 millisecond average/1 millisecond update rate)

Medium: 45 Hz (10 milliseconds average/2 milliseconds update rate)

Slow: 4.5 Hz (100 milliseconds average/4 milliseconds update rate)

Retroreﬂective Analog Voltage output (-3 dB)

Fast: 114 Hz (6 milliseconds average/ 1 millisecond update rate)

Medium: 10 Hz (48 milliseconds average/ 1 millisecond update rate)

Slow: 2.5 Hz (192 milliseconds average/ 1 millisecond update rate)

Resolution/Repeatability

See charts RRC-1 and RRC-2 on page 299.

Color Sensitivity (typical)

Diffuse: 90% white to 18% gray: less than 10 mm; 90% white to 6% black: less than 20 mm.

See chart CSC-1 on page 299.

Analog Linearity

Retroreﬂective: ± 60 mm from 0.5 to 50 m (0.12% of full scale)

(Specied @ 24V dc, 22° C using supplied BRT-TVHG-8X10P retroreector)

Diffuse: ± 30 mm from 0.3 to 1.5 m; ± 20 mm from 1.5 to 5 m

(Specied @ 24V dc, 22° C using a 90% reectance white card)

Discrete Output Hysteresis

Diffuse

Fast: 10 mm

Medium: 5 mm

Slow: 3 mm

Retroreﬂective

Fast: 20 mm

Medium: 10 mm

Slow: 6 mm

Temperature Effect

Diffuse: less than 2 mm/ ° C Retroreﬂective: less than 3 mm/° C

Minimum Window Size

Diffuse: 20 mm Retroreﬂective: 40 mm

Remote TEACH Input

18 kΩ min. (65 kΩ at 5V dc)

Remote TEACH

To teach: Connect yellow wire to +5 to 24V dc

To disable: Connect yellow wire to 0 to +2V dc (or open connection)

Adjustments

Response speed: Push button toggles between fast, medium and slow (see Output Response Time)

Window limits (analog or discrete): TEACH-mode programming of near and far window limits. Limits may also be taught

remotely using TEACH input.

Analog output slope:

The rst limit taught is assigned to minimum output current or voltage (4 mA or 0V dc)

Laser Control

Connect red wire to +5 to 24V dc to enable laser beam; connect to 0 to +1.8V dc (or open connection) to disable. See data sheet

for delay time on enable.

Indicators

Green Power ON LED: Indicates when power is ON, overloaded output and laser status

Yellow Output LED: Indicates when discrete load output is conducting

Red Signal LED: Indicates target is within sensing range and the condition of the received light signal

Yellow Speed LED: Indicates the response speed setting

Red/Yellow TEACH LEDs: In programming mode; indicate active output(s)

Construction

Housing: ABS/polycarbonate blend

Window: Acrylic

Quick-disconnect: ABS/polycarbonate blend

Environmental Rating

IP67; NEMA 6

Connections

2 m or 9 m shielded 7-conductor (with drain) PVC-jacketed attached cable, or 8-pin Euro-style quick-disconnect. QD cordsets are

ordered separately. See page 299.

Operating Conditions

Temperature: 0° to +50° C Relative humidity: 90% at 50° C (non-condensing)

Application Notes

• For best accuracy, allow 30-minute warm-up before programming or operating

• Retroreective performance specications are based on use with supplied BRT-TVHG-8X10P

high-grade target. Results may vary with other retroreective target materials.
