Indicators
Standard and programmable K50 Indicators cover everything from basic status indication to complex visual signaling across a wide range of applications. Model variants include beacon, audible, and daylight-visible, ensuring unmistakable indication indoors and out, while IP66/IP67/IP69K ratings support long-term performance in demanding conditions.
Standard models offer immediate deployment with up to five fixed colors and are available in compact, domed, and flat pack housings, as well as specialty housings for hazardous zones and hygienic environments.
Programmable models provide configurable RGB LED response and support for real-time control over IO-Link or Modbus. 14 colors and 11 animations can be configured using Banner’s free Pro Editor software or controlled dynamically via protocol.
Ergonomic Interaction, Dynamic Indication
Touch Buttons
K50 Touch Buttons combine advanced touch technology with unmistakable status indication that translates process signals into clear, interactive feedback. Available in domed or compact housings, all models streamline panel design by replacing multiple conventional buttons with a single device that supports latching or momentary functions and can be operated without pressure—reducing strain and improving ergonomics.
Standard models are ready out of the box with up to three fixed colors, selectable based on input priority. All models are IP66/IP67/IP69K-rated for reliable performance in demanding environments.
Programmable models extend functionality with configurable touch response, multiple I/O modes, and support for real-time control over IO-Link or Modbus. Color, animation, and on/off delays can be configured using free Pro Editor software or controlled dynamically via protocol.
Variants include models with audible output, integrated displays, and FDA-grade housings for hygienic environments.
Contactless Interaction, Dynamic Indication
Touchless Buttons
K50 Touchless Buttons deliver reliable, no-contact activation with unmistakable status indication—ideal for reducing touchpoints in high-cycle applications. Configurable optical sensing from 20 to 1000 millimeters ensures responsive operation tailored to the task. 14 color options, 11 animations, and on/off delays—all configurable using free Pro Editor software or controlled dynamically via IO-Link or Modbus—provide visual feedback that makes any process more intuitive. Support for Banner’s PICK-IQ protocol enables real-time feedback and faster updates in dense systems.
Lightweight construction provides a cost-efficient solution while maintaining IP66/IP67/IP69K-rated protection for harsh industrial environments. With no moving parts and built-in immunity to ambient light, EMI, and RFI, K50 Touchless Buttons ensure long-lasting, zero-contact control in demanding applications.

Applications
Proven Solutions that Keep Operations Running
-
-
Assembly Timer at Busy Work Station
K50 Pro touch buttons with IO-Link communication display takt time within workers' sightlines so that the assembly pace stays on track and meets production goals.
-
Machine Status Indication in Automated Clinical Laboratories
Clinical labs need to process samples quickly to keep throughput high and any lag during testing procedures would disrupt workflow. LED lightings, such as the K50L2, works as machine status indication so that the lab operators can process fix errors, handle samples, and collect results in a timely manner.
-
Communication in a Busy Manufacturing Site
As more components pass through the oven, keeping pace with the flow of items to be unloaded becomes increasingly difficult. Congestion in the sortation area builds. Items can easily be misdirected or even damaged. A pause in the flow of parts allows the unloading operator to correct mistakes and clear a pickup station. However, the distance between the unloading and loading areas as well as ambient interference from surrounding machinery complicates communication between operators.
-
Bright Indication in Ambient Light
When a window is located directly behind a cabinet, extremely bright, long lasting LED indicator lights can provide highly visible indication throughout the day. Banner’s EZ-LIGHT K50 Beacon is perfect for many indication status applications, especially in this cabinet because the beacon is highly visible even during daylight and is extremely durable with long-lasting, energy-efficient LEDs.
-
Reach Stacker Status
Visual indication is an easy, effective way to communicate status to keep equipment operating efficiently and increase productivity. Intensely bright beacon lights are highly visible during daylight and indicate the condition of the spreader twist locks to the operator cabin to ensure a secure lift. The beacon lights feature intense levels of light output and are very rugged and durable, making them ideal for outdoor indication applications.
-
Pick Indication and Verification
Push-button EZ-LIGHT K50 pick-to-light sensors on a rack of parts light up to indicate which parts to pick. After picking a part, the worker pushes the button on the indicator light to verify that the pick is complete.
-
Incorrect Pick Signal
The EZ-LIGHT K50 sensor lights above a bin to show the assembler which part to pick. If the assembler reaches into a different bin, that bin's EZ-LIGHT K50 sensor lights up in the designated warning color—in this example, red— to indicate the error.
-
Call for Parts at a Furniture Manufacturer
The customer needs a solution that can increase the forklift operator's response time by putting indicators on the forklift's dashboard and can also allow the forklift operator to acknowledge the request, which eliminates redundant part deliveries by multiple operators.
-
Emergency Stop Indication
With the all-in-one enclosure, the emergency stop pushbutton combined with the K50 Touch lighted indicator communicates simple status indication in emergency conditions.
-
Wireless Call for Parts
A system of Banner’s TL70 wireless modular tower lights and K50 touch buttons provides an efficient, easy way to communicate a call for more parts with a forklift driver. When a workstation is almost out of cartons, the operator touches the ergonomic K50 touch button which changes the status on the connected TL70 wireless tower light to red.
