Inductive Linear Transducers for engineering and instrumentation.
The half-bridge technology for 1 to 360 mm stroke. The wide range of inductive linear transducers includes items with 10, 12 and 25 mm outside diameter and for measuring ranges from 1 to 360 mm. The smaller IW 10 and IW 120 series require external electronic modules for excitation and signal conditioning. IW 250 series with 25 mm housings have integral electronics consisting of oscillator, demodulater and amplifier. Analogue output signals are either 0(4) to 20 mA, 0 to 10 VDC or ± 10 VDC for full range or calibrated strokes. The transducers are completely potted to meet protection grades up to IP 68. Electrical connection is made either by leads, plug and socket or through cable glands. Various mechanical configurations are available to suit specific mounting conditions.
The IW 260 displacement transducers operate according to the new principle of fractional inductivity allotment within the hollow coil. Depending on the position of the core the inductivity changes within the corresponding coil section. This kind of layout provides for more position data than the classical half-bridge or LVDT configuration. An integral electronic circuit transforms these data into a signal proportional to the displacement of the plunger core.
The electronic circuit contains an oscillator, a demodulator, an amplifier and in some cases a current output source. Its SMD-design is short-circuit proof and protected against reverse polarity. The sensor system is completely sealed within a non-corrosive steel case to ensure positive protection against vibration, shock, humidity, oil and corrosive matter.
The new principle of fractional inductivity allotment as described above brings about an outstanding increase of the measuring stroke. In comparison to the IW 250 model the useful range of the IW 260 model increases by 70 to 100% based on the same length of the case.
Expanded Line of Geared Resolvers Eliminates Gear Reducers in Many Position Sensing/Control Applications. Electro Cam Corp. has expanded its offering of geared resolvers to include ratios from 2:1 to 36:1, eliminating the need for external gear reducers in many applications where outputs are tracked over multiple revolutions, and significantly increasing resolver input effectiveness.
Coupled with Internal High-Speed Logic technology in Electro Cam Corp.’s PLµS controllers, the wide range of geared resolvers makes it feasible to control the majority of machine processes.
Electro Cam geared resolvers have a specific ratio of resolver input shaft turns to resolver shaft turns. The gear reduction allows users to convert multiple machine shaft revolutions into one resolver shaft revolution without adding gear boxes, pulleys, or sprockets to obtain proper ratios.
The new geared resolvers are ideal for a variety of applications, including form/fill/seal packaging machines, cartoners, conveyors, printing, silk screening, lumber processing, metal grinding, and material handling equipment.
All Electro Cam resolvers feature heavy-duty dual bearing construction and standard mounting configurations.

Full range of models designed to match specific encoders are
supplied with shaft size adaptors
CPL Series couplings are carefully matched to the requirements of our encoders and are an excellent, low cost way to protect your investment and avoid equipment downtime.
The method of coupling rotational input to an encoder is an important consideration. Excessive shaft loading and poor environmental
isolation are the leading causes of encoder failure and operational errors.
Even the most carefully designed machinery will produce shaft forces due to inherent thrusts, and eccentricities. Since encoder shafts and bearings must be engineered to have very restricted axial and radial play, using a Dynapar brand CPL Series coupling affords maximum protection against these common hazards.
A unique 3-beam design divides the coupling’s helix into three segments.
This feature maintains transfer accuracy by restricting windup during torque, yet retains full protective flexibility. In addition to controlling mechanical shaft and bearing loads, the coupling further protects the encoder by providing a high degree of electrical and thermal isolation between coupled shafts. This is accomplished with a phenolic insulator-insert that blocks passage of potentially damaging heat, electrical currents and static charges.
Each CPL Series coupling is supplied with two insulator-inserts (three for metric models) that allow it to fit standard shaft diameters (see Models table, Secondary Bore). Attachment at both ends is via integral 360° clamps that firmly grip the encoder shaft and input shaft, remaining slip-free to the rated
torque of the coupling.
