  • Fife SE-15 Visible Light Sensor

    Small, yet accurate, the SE-15 Visible Light Sensor is perfect for web applications where exact guiding is required and space is limited. With a control range of 10.2 mm (0.4 inch), this compact, lightweight sensor is best suited for edge guiding opaque, transparent, or reflective materials in most unwind and rewind applications.

    This medium-gap reflex sensor utilizes a reflector mounted on the opposite side of the web and a co-axis optical visible red light for transmitted and received light beams. The effective gap between reflector and sensor can range from 25 mm (1 inch) up to 1 meter (39 inches). The sensor light signal is processed to filter out ambient and reflected light to provide reliable and accurate performance.

  • Fife DSE-17 Wide Band Infrared Sensor

    The DSE-17 is a digital wide proportional band infrared sensor. The sensor is most suitable for applications where opacity or density variations may occur, such as tissue, non-woven, textile, paper, foil, and for many opaque films. It can track up to 4 independent web edges simultaneously.

    When web width variations exist, the wide proportional band of the DSE-17 sensor eliminates the need for the manual repositioning of the sensor.

    Thanks to its IP-65 rating the DSE-17 can be installed even in the presence of water spray or condensation. The digital technique is immune to higher levels of contamination, compared with traditional analog sensors. The contamination of the sensor acrylic window can be monitored via a proportional analog output signal. An air sweep system is available as an option. In addition the DSE-17 sensor is protected against the influence of ambient light.

  • Fife SE-31 Intrinsically Safe Ultrasonic Sensor

    The SE-31-IS Ultrasonic Sensor is specifically designed to perform in hazardous locations, Class I, Division 1, Groups C & D. Ideal for guiding thin or clear films, as well as most opaque webs, this sensor is fully certified under UL, cUL (US and Canada), and CENELEC (Europe).

    The SE-31-IS has control range of 7.62 mm (0.3 inch), a sensing gap of 50.8 mm (2.0 inches), and requires the same 12 VDC power supply as most other Fife sensors. The maximum sensor voltage and current is protected through a safety barrier
    located outside of the hazardous area. Maximum cable length from the sensor to the controller is 4.19 m (165 feet).

  • Fife SE-42 Infrared Light Sensor

    The SE-42 Sensor uses modulate infrared light. It’s light weight, small size and insensitivity to ambient light make it ideal for most web guiding applications

    The SE – 42 Infrared Sensor measures the lateral position of the guided material photoelectrically. The control range (proportional band) is 17 mm, allowing
    significant guide point adjustment. The SE – 42 is often used in pairs for center guiding when web width variations are limited. The SE – 42 sensor can be used
    to guide either opaque or transparent materials.

    Fife offers a wide variety of sensor mountings and
    positioning assemblies for use with the SE – 42 infrared sensor.
    Depending on the application, standard or custom designed mounting
    brackets can be provided to ensure quick and easy installations.

    The SE – 42 can be used with any of our applicable guiding systems or as a retrofit / upgrade for
    existing systems.

    The SE – 42 can be connected to all available Fife web guide controllers
