    Light Beam Finger-Touch Switches

    Image of Product. Front orientation. Finger-Touch Switches. Light Beam Finger-Touch Switches.
    An infrared light beam senses the lightest finger contact to switch a circuit on or off. The included guard prevents accidental activation. An indicator lights up to confirm that switches are actuated. They’re rated NEMA 4X, 13, and IP66 for protection from corrosion, washdowns, and oil/coolant spraying.
    M22 Connection—Switches with a 5-pole M22 connection can quickly be changed out.

    The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity. Change the color to show different process statuses. For more visibility, change the intensity of the color or choose a light pattern. These switches can flash, rotate, and show other patterns, all at speeds you can control. To change how much force they need to actuate, alter the sensitivity. With a high sensitivity, they’ll actuate even if you’re wearing gloves. With a low sensitivity, they’re more resistant to accidental actuation.
    To program your switch, download the free Banner Pro Editor Software. You’ll need a switch programming kit (sold separately) to connect your switch to the software.
    Copolyester Actuator Base—Switches with a copolyester base are FDA compliant for incidental food contact once installed.
    Style D—Style D switches let you program their action to be momentary or maintained.
    Audible Alarm Alert—Switches with an audible alarm can be programmed to 12 different tones ranging from sirens to melodies.

    Two-Hand Finger-Touch Safety Switches

    Image of Product. Front orientation. Finger-Touch Switches. Two-Hand Finger-Touch Safety Switches.
    It takes two hands to activate these switches, minimizing the risk of accidental equipment start-up. They have an emergency stop push-button to immediately cut power. They’re rated IP65 for protection from low-pressure washdowns.
    Switches turn circuits on and off with a light touch, even when wearing gloves. An infrared sensor detects the lightest finger contact, and an indicator lights up to confirm when they are activated. Because they don't require you to press down a button to operate, they meet ANSI B11.TR1 standards to reduce hand, wrist, and arm fatigue. You'll need a relay or controller to complete your system—upgrade to a controller if you plan to operate additional devices beyond your switch.

    With just a light touch, these switches turn circuits on and off in sanitary areas—even when you're wearing gloves. They're ideal for environments that require frequent cleaning, such as food and pharmaceutical plants. Their smooth, crevice-free surfaces are easy to clean and prevent bacteria buildup. Rated IP69K, they withstand high-pressure, high-temperature washdowns. They help you comply with European Hygienic Engineering and Design Group (EHEDG) sanitary standards.
    These switches use IO Link, so you can change settings, view outputs, and receive error messages from a connected programmable logic controller (PLC) or computer. Commonly used on production lines, they alert your team to equipment issues as soon as they occur.

    Suitable for areas with space limitations, these switches have a low profile and a small footprint. They lay flat or mount to a wall. Typically used in start/stop and door opening applications, switches can also be placed underneath objects to alert when the object is removed. All have a sealed housing that resists water and alcohols (not suitable for continuous contact).

    Use fingerprints to confirm the identity of personnel before granting access to secure areas or equipment. Scanners light up green to indicate that they have accepted the fingerprint and are sending an output signal. The front faces of the scanners meet NEMA 12 and IP65. The rear faces of the scanners meet IP20.
    Fingerprint Scanner Covers—Covers (sold separately) have an adhesive-back hinge, so you can stick them on to your scanner. Keep the cover flipped down to protect the scanner's sensor from dust and debris.
