Chip
Besides its basic functions (oscillator, demodulator and threshold switch), the bipolar
monolithic IC TCA 505 B includes a number of useful extra functions that enable high-grade,
inductive proximity switches to be designed for an attractive price/performance ratio and with
space savings.
Compared to earlier ICs for inductive proximity switches temperature drift, noise immunity and
the switching frequency of the IC have been improved.
