Page 117 Heidenhain: Diagnostics-Equipped Encoders
Schaumburg, IL — Heidenhain has introduced an updated version of the popular ADS (Advanced Diagnostic System) from Leine and Linde. The new ADS Online is Leine and Linde’s proprietary encoder diagnostic tool. Currently available on Leine and Linde’s robust models 801 and 803 rotary encoder products, the encoder operates by a connection from its
tions or trends of the encoder from anywhere worldwide. With the assistance of PC soft-
ware, users can obtain detailed analyses of encoder performance and projected needs for maintenance and/or replacement. The ADS Online System obtains data and analyzes rotary encoders in operation and warns of impending faults before they occur. The ADS System is espe- cially useful for monitoring and ana- lyzing encoder operation in large, complex machinery such as that used in the exploration of oil and natural gas, wind turbines, and paper-con- verting machines. Designed to support condition- based maintenance, the ADS System
helps to identify encoder mainte- nance needs when necessary, and in ample time to avoid unforeseen pro- duction stoppages. According to com- pany sources, large complex machin- ery typically depends on an encoder as a central and critical component for speed feedback. Temperature, operating speed and vibration are examples of factors that affect encoder service life and are unique for each application. Since encoders are subject to
wear (service life can vary from a couple of years to a couple of decades), an ADS Online system allows users to better predict and schedule maintenance at convenient times instead of waiting for inoppor-
tune breakdowns. ADS Online users can program custom warnings to ensure that vibration doesn’t exceed damaging levels; they can set levels for frequency and shaft speeds to indicate overspeed or standstills, and set parameters for temperature and voltage to ensure that the encoder and machine do not overheat or suf- fer damage from power supply volt- age drops. Users can also program in automatic warnings for maintenance or replacement when an encoder
reaches a specified operating time. Contact: Heidenhain Corpora tion,

Efficient LED Replacement Lamps from APEM
Haverhill, MA — APEM Compo - nents, Inc. has introduced a range of reliable and energy-efficient LED lamps fitted with standard bases (screw-in, bayonet) making them suitable as drop-in replacements for
Capacitors for Power Electronics
LED lamps with mounting bases.
existing incandescent or compact flu- orescent (CFL) lamp products. Based LED lamps offer an
extended lifetime of 100,000 hours, low power consumption, low heat generation, and excellent shock and vibration resistance, Their long serv- ice life reduces the total cost of own- ership and their high reliability makes the product line suitable for critical applications where the pres- ence of indication is essential or where lamp replacement is difficult or time-consuming. The APEM range of based LEDs
is available in several options, including high intensity single-chip LED, cluster, and multi-chip ver- sions. Integral resistors allow direct connection from 6V through 230V,
depending upon the model selected. Contact: APEM Components,
