We offer consultancy for AI-TEK speed sensor accessories

Accessories for Speed Sensors
AI-Tek Instruments have designed and manufactured a variety of durable speed sensor accessories for your convenience. These accessories are recommended to ensure that your AI-Tek sensors operate at peak performance. For more detailed product information on the accessories, be sure to visit our Brochures & Catalogs section.

Split Gears & Solid Gears
Split Gears: When using an AI-Tek speed sensor in RPM measurement, split gears provide a convenient and simple means of installation where shaft disassembly is not feasible. The two halves of the gear are fastened with clamping screws, thus assuring close fit. All split gears are 12 diametral pitch, 14.5° pressure angle.

Solid Gears: AI-Tek also offers a 20 diametral pitch, 14.5° pressure angle, solid steel gear. This gear can be rebored to fit shaft diameters up to 3.750". It is secured to the shaft with 2 set screws.

Connectors and Cable Assemblies
AI-Tek stocks a selection of connectors and cable assemblies for your convenience. For ease of selection, the connectors and assemblies are divided into groups:

Group "A" is designed for 2-wire items
Group "B" for 3-wire
Group "C" for 5-wire

Complete cable assemblies include the connector and 10' of recommended wiring for use with AI-Tek equipment. All wiring is insulated, spirally wrapped in a tinned copper shield and jacketed in long-lasting PVC, Teflon or polyolefin insulation. Alternate cable length is 50', use -050 for final suffix.

Tachometer Transducers
AI-Tek tachometer transducers are self-generating units when used with speed sensors, designed to:

Attach a pulse generating assembly to rotating shafts with ease.
Eliminate sensor gapping, shaft run-out and mounting problems.
Used for shafts with high run-out.

Sleeve-Type Transducer
The AI-Tek sleeve-type transducer assembly is identical to the Taper-Lock type except that it provides a sleeve bushing with two set screws for installation purposes, allowing larger shaft sizes.

Taper-Lock
The assembly consists of a Taper-Lock bushing which enables quick attachment to rotating shafts. As the transducer employs a rotor with small perforations along its periphery (a permanently lubricated sealed bearing) an outer ring and a reference rod which, when clamped in position, prevent the outer ring assembly from moving. The outer ring can accommodate up to three-speed sensors for use in monitoring directions of rotation and speed.

Sensor Mounting Brackets
Several types of brackets are available to facilitate the mounting of AI-Tek speed sensors:

Passive sensors require threaded brackets for 3/8-24, 5/8-18 and 3/4-20 threads with one locknut.
Active, zero-velocity sensors and passive, chisel-point sensors that require specific alignment should be used with unthreaded brackets and two locknuts.
Bracket material is non-magnetic, 303 stainless steel; locknuts are also non-magnetic stainless steel or plated brass.
