Custom Magnetic Sensors and Reed Switches

We have a wide array of sensor output options such as reed and Hall effect digital output, single- and multipoint reed ladder fluid level measurement, ratio-metric output for rotary angle and linear measurement using Hall effect devices, and speed and direction sensing.

Types of Customization:

  • Modifications to existing standard product packages, such as adding connectors or changing wire size or length, as well as offering special reed switch sensitivities, custom lead forming and bending, or modifications to bare reed switches
  • Fully new custom sensor package designs and/or circuitry
  • Magnetic circuit (actuator magnet and sensor) design for a variety of applications

Engineering Services Offered:

  • 3D CAD mechanical design services
  • Electronic circuitry design
  • Magnetic simulation supports analyzing feasibility of the design options
  • 3D mapping of magnetic actuation of the sensor
  • Rapid prototyping and quick-turn concept parts including 3D-printed parts
  • Prototype units using prototype tooling
  • Reliability/Validation testing options
  • Fully designed production-capable sensor and tooling

Reed Relays

A reed relay combines a reed switch with a coil into one package to serve as a smaller, more power-efficient alternative to other types of relays.  These relays are well suited for use in automated test equipment, security, medical, and process control equipment. Options for customization are available.

Reed Switches

Littelfuse offers the widest selection of magnetically operated reed switches.  Reed switches are available in bare glass or overmolded packages with a variety of mechanical, electrical, and magnetic characteristics. Options for customization, such as lead cutting and forming, are available.

Automotive Qualified MOSFETs

These MOSFET devices have been extensively tested and approved for the rigorous automotive applications.

Fuses

Littelfuse manufactures the broadest and most innovative selection of fuses to serve nearly every possible application.

Fuse Clips

Along with fuse holders and fuse covers, fuse clips are designed to provide a tight enclosure between the clip and the actual fuse.

Fuse Holders

Littelfuse offers a comprehensive line of fuse blocks, fuse holders, and fuse accessories for automotive, electronic, and electrical markets.

Fuse Blocks

When used with the correct fuses, fuse blocks help protect the wiring in electrical circuits.

HMI Solutions (X Series E-stop)

IDEC now offers a new series of E-stops that provide an even higher level of function and safety to customers. These 30mm XN E-stops are the first and only with exciting, new technology to make machines even safer.

Features include our unique “Safe Break Action,” which ensures NC contacts will open if the contact block is damaged or separated from the operator due to excessive force. Direct Opening Action ensures that even if the contacts are welded, the force applied to the button will directly open the contact. A Safety Interlock Mechanism keeps contacts open when the operator is locked.

Inspired by the lockout concept, the new XN series of padlock-type E-stops were developed to prevent unauthorized or accidental resetting of latched emergency stop switches, by allowing the use of up to 20 personal padlocks*. XN1E series E-stops save space behind the panel with depths of only 47.7mm for up to four contacts. And XN5E series E-stops only extend 21mm from the front of the panel, ideal for applications needing a low-profile design.

Key Features

  • Available in plastic bezel, metallic padlock, flush bezel
  • Only 47.7mm depth behind the panel for up to 4 contacts (XN1E)
  • Unique “Safe Break Action”
  • Direct Opening Action (IEC60947-5-5, 5.2, IEC60947-5-1, Annex-K)
  • Safety Lock mechanism (IEC60947-5-5, 6.2)
  • Push-to-lock, pull/turn-to-reset built into one switch(XN1E and XN5E); Push-to-lock, turn-to-reset (XN4E)
  • RoHS compliant, lead-free design, UL-listed, cUL, TUV, CE

HMI Solutions (LBW Flush)

Welcome to the LBW series, a new breed of 22mm flush mount switch family that offers hundreds of styles and numerous features.

Available in face- or ring-illuminated pushbuttons, flush or extended pushbuttons, pilot lights, selector switches, and key selector switches, the LBW Series is perfect for applications for medical devices, food and beverage processing equipment, semiconductor equipment, demo equipment, home automation, and robotic control systems where a hygienic surface is required. A smooth surface design prevents particles and debris from accumulating and makes regular cleaning a breeze. LBW flush mount switches also remove the obstacles from busy control panels where a flat surface is desirable to allow frequent finger travels. The compact and space-saving design of the LBW series also enables breakthrough in stylish and modern design by reducing the machine’s panel size while enhancing its functionality and controllability.

Key Features

  • Projects only 2mm from the panel surface
  • ø26mm bright and clear illumination surface
  • Bezel choice of round/square, black/metallic, and guards
  • 34.9mm shortest body in the class
  • Easy wiring with removable contact blocks
  • Wide variety of flush/extended pushbuttons, face-/ring-illuminated pushbuttons, selector/key switches, and pilot lights
  • 5A Contact Rating
  • IP65 Protection
  • Key switches use wave keys that are hard to duplicate
  • 6 Different keys are available besides the standard key
  • Reliable gold-clad or silver contacts
  • Solder tab or PCB terminals
