** For 9 m cable, add suffix W/30 to the 2 m model number (example, T18AW3FF25 W/30). A model with a QD requires a mating cable (see page 386).

T18 AC Specifications

Supply Voltage and Current

20 to 250V ac (50/60 Hz). Average current 20 mA. Peak current: 200 mA at 20V ac, 500 mA at 120V ac, 750 mA at 250V ac

Supply Protection Circuitry

Protected against transient voltages

Output Configuration

SPST solid-state ac switch; three-wire hookup; Light Operate (LO) or Dark Operate (DO), depending on model.

Light operate: Output conducts when the sensor sees its own (or the emitter’s) modulated light

Dark operate: Output conducts when sensor sees dark

Output Rating

300 mA max. (continuous) Fixed-field models: derate 5 mA/° C above +50° C;

Inrush capability: 1 amp for 20 milliseconds, non-repetitive

Off-state leakage current: less than 100 mA

On-state voltage drop: 3V at 300 mA ac; 2V at 15 mA ac

Output Protection Circuitry

Protected against false pulse on power-up

Output Response Time

Opposed Mode: 16 milliseconds ON, 8 milliseconds OFF

Polarized Retroreflective, Non-polarized Retroreflective, Fixed-field & Diffuse: 16 milliseconds ON/OFF

NOTE: 100 millisecond delay on power-up

Repeatability

Opposed Mode: 2 ms; Polarized Retroreflective, Non-polarized Retroreflective, Fixed-field, and

Diffuse: 4 milliseconds Repeatability and response are independent of signal strength.

Adjustments

T18 Series infrared non-polarized retroreflective and diffuse mode models (only) have a single-turn rear-panel

SENSITIVITY control for adjustment of system gain (turn clockwise to increase)

Indicators

Two LEDs: Green and Yellow

Green ON steady: power to sensor is ON

Yellow ON steady: sensor sees light

Yellow flashing: excess gain marginal (1-1.5x) in light condition

Construction

Housings are thermoplastic polyester. Lenses are polycarbonate or acrylic; T18 models come with one jam nut.

Environmental Rating

Leakproof design rated NEMA 6P, DIN 40050 (IP69K)

Connections

2 m or 9 m attached cable, or 4 pin Micro-style quick-disconnect fitting. QD cables are ordered separately. See

page 386.

Operating Conditions

Temperature: -40° to +70° C

Relative humidity: 90% at 50° C (non-condensing)

Vibration and

Mechanical Shock

All models meet Mil. Std. 202F requirements. Method 201A (Vibration; frequency 10 to 60 Hz, max, double

amplitude 0.06-inch acceleration 10G). Method 213B conditions H&I (Shock: 75G with unit operating; 100G for

non-operation)
