Not To Be Used for Personnel Protection
Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.
These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner
Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

* T18U receivers may be wired for either of two resolution modes: Normal or High (see hookup diagrams, page 4).
** Only standard 2 m (6.5’) cable models are listed. For 4-Pin Euro-Style integral QD, add suffix “Q” to the model number (e.g., T18VN6URQ). For 9 m (30’) cable, add suffix
“W/30” to the model number (e.g., T18VN6UR W/30). A model with a QD connector requires a mating cable; see page 4.

* In general, the minimum object width and minimum object spacing will decrease if the object

Individual results may differ based on ambient operating conditions, alignment, and the
geometry of the objects to be detected.

Overview
U-GAGE® T18U Series Sensors are opposed mode ultrasonic emitter/receiver pairs. They utilize an advanced built-in microprocessor to
analyze the received ultrasonic signal and control an indicator LED located on the back of the receiver. The receiver LED flashes at a rate
proportional to the received sonic signal strength. This indicator greatly simplifies sensor alignment and alerts personnel to marginal sensing
conditions due to gradual misalignment or environmental factors. The receiver is precisely tuned to the ultrasonic emitter, making this sensor
pair highly immune to both sonic and electrical ambient noise.
T18U receivers may be wired for either of two resolution modes: NORMAL or HIGH. The modes are selected by the polarity of the supply
voltage (see hookup diagrams, page 4). The NORMAL resolution mode offers a sensing range of 600 mm (24") and maximizes sensing
energy, as is required in demanding environments. The HIGH resolution mode yields a sensing range of up to 300 mm (12") and maximizes
sensing response, as is needed in high-speed counting applications.
Opposed mode ultrasonics are very useful for highly reliable sensing of clear materials, which is always a challenge for photoelectric modes.
T18U Series ultrasonic sensors are designed for demanding sensing environments. Housings are tough, NEMA 6P-rated PBT. Electronics are
epoxy encapsulated. The acoustic face of both emitter and receiver are epoxy-reinforced for extreme durability and moisture resistance.
