WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious
injury or death. This device does not include the self-checking redundant circuitry necessary to allow its
use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-
energized sensor output condition.
Overview
Banner VTB Series touch buttons are ergonomically designed to eliminate the hand, wrist, and arm stresses associated with mechanical
push buttons. They require absolutely no physical pressure to operate. LED indicators light when power is on and outputs are activated.
The interfaces to a system controller, which is pre-programmed for a specific sequence of tasks. Mounted in or near each bin in an
assembler’s work station, the sensor job light signals the assembler which bins contain items to be picked in a given operation and in
what order they should be picked.
As the assembler takes a part in sequence , then reaches a finger into the yoke of the corresponding Touch Button, the sensor senses
that the part was removed and it sends an output signal to the controller. The controller then verifies if the correct part was taken and may
respond by turning that job light OFF, activating the job light of the next bin in the sequence.
All models are immune to EMI, RFI, and ambient light interference. VTBs have either a black polysulfone or red polycarbonate upper
housing (depending on model) and a translucent white polycarbonate base. Environmental considerations for use of the two upper hous-
ing types differ; see specifications. The entire base section lights to provide a bright job light where a task is to be performed. The 30 mm
threaded base on all models provides easy mounting.
