• Intrinsic safety ground, if required for the Associated Apparatus, shall be less than 1 ohm.

• Maximum connector torque: 6 ft-lbs.

Wiring Connections

Q45AD9 Series NUMAR sensors are intrinsically safe ONLY when used with certified intrinsically safe switching amplifiers and barriers

(Approved Apparatus) with intrinsically safe circuits. Banner does not manufacture such devices; however, our applications engineers

can refer you to suppliers of certified devices that will interface with Banner sensors.

The user is responsible for proper installation and maintenance of this equipment, and must conform with the certification

requirements relating to barriers and to maximum allowable capacitance and inductance of the field wiring. If in doubt about these

requirements, our applications engineers can refer you to the appropriate authority.

Specifications for Q45 NAMUR Sensors

Supply Voltage and Current

5 to 15 V dc. Supply voltage is provided by the amplifier to which the sensor is

connected.

Adjustments

Multi-turn sensitivity control on top of sensor, beneath a transparent o-ring

sealed cover, allows precise sensitivity setting (turn clockwise to increase gain).

Output

Constant current output: ≤ 1.2 mA in the “dark” condition and ≥ 2.1 mA in the

“light” condition

Output Response Time

Opposed mode receiver: 2 milliseconds on/0.4 milliseconds off. All others 5

milliseconds on/off (does not include amplifier response)

Construction

cover, molded acrylic lenses, and stainless steel hardware. Q45s are designed

to withstand 1200 psi washdown. The base of cabled models has a 1/2-inch

Environmental Rating

Banner tested to NEMA 6P, IEC IP67

Application Note

Special Conditions for Safe Use: Parts of the enclosure are non-conducting and

may generate an ignition-capable level of ESD. Cleaning of the equipment must

be done only with a damp cloth.

Indicators

Indicator LEDs are highly visible, located beneath a raised transparent dome on

top of the sensor.

POWER (red) LED (emitters only) lights whenever 5 to 15 V dc power is applied

SIGNAL (red) LED lights whenever the sensor sees its modulated light source

Connections

PVC-jacketed 2 m (6.5 ft) or 9 m (30 ft) cables, or 4-pin Euro-style quick-

disconnect (QD) fitting are available. QD cables are ordered separately. See

Accessories.

Operating Conditions

Temperature: −40 °C to +70 °C (−40 °F to +158 °F)

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