E-Series Models — 2 Colors

• Job light is green at all times while job input is active

• Presence of hand (or pressing push button) activates output

• Presence of hand (or pressing push button) while job input is inactive causes unit to light red, providing visual verification that

sensor is functioning properly

Overview

The K50 & K80 Pick-to-Light Sensors are suited to many part assembly and bin picking (pick-to-light) applications.

The entire translucent dome provides the green job light or other indication (depending on model), for high visibility. The solid-state

output easily 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, the K50 or K80 senses a hand in the bin and its output sends a signal to the controller. (For

push-button models, the sensing occurs when the button is pushed. For other models, no action other than reaching for the part is

required for the sensor to detect when a pick is made.)

The system controller then verifies if the correct part was taken and may respond by turning that job light OFF and activating the job

light of the next bin in the sequence. If multiple parts are to be removed from one bin, the job light may remain ON until the

appropriate number of signals is returned to the controller. If an incorrect part is selected, the control system may be wired to signal an

alarm for the assembler and/or a supervisor, or it may be programmed to interpret the action as a call for parts.

The job light system results in increased efficiency (due to simplified job training), increased quality control (no skipped components),

and reduced rework and inspections. It speeds the resumption of work after breaks and other distractions and is ideal for multilingual

workplaces where communication is an issue.

The fixed-field and retroreflective-mode models require no interaction to operate, and so eliminate the hand, wrist, and arm stresses

associated with mechanical push buttons. All models are immune to EMI, RFI, and ambient light interference. The polycarbonate and

nylon housing is capable of absorbing high impact (even at low temperatures) and is resistant to abrasion and to damage by most

chemicals. Its domed construction allows most dust and debris to slide easily off the sensor housing, simplifying maintenance. The 30

mm threaded base on all models provides easy mounting. Indicator behavior is shown in the table below.
