Voltage measurement
The Model 542 Electrostatic Voltmeter from this company is the latest addition to its line of EOS/ESD detection products. The microprocessor-based meter uses a
dc stable electrostatic field chopper probe for semiconductor, LCD, electronic assembly, and other applications where static charge accumulation poses a threat to production yields or product quality.

Linear
encoders
With a grating pitch of 20 microns, the LIDA 400 encoder is for use on linear motors, placement machines, PCB-drilling machines, or in CMM handling applications. With a scanning head height of only 12 mm, the LIDA 400 can be installed in tight spaces. Yet, the small scanning head supplies a large scanning area of 14.5 mm 2 .

Modular
encoder
A self-aligning, self-centering, self-gapping, size 15 modular encoder has an axial length of 0.84 inch maximum. The encoder is mounted with a single push on a patented slide lock mechanism. The cover has an integral positive lock-on mechanism, which eliminates mounting hardware. Its operating temperature is from -10 to 100C with frequency response up to 200 kHz.
