Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

HIN1P33

IEEE / ANSI

ANSI/IEEE Minute-pulse clock contact form

This reference locates minute-pulse clock contact in Autodesk's IEEE-oriented instrumentation and sensors family. This representation identifies the publisher's normally-open clock contact that closes every minute. The public library uses HIN1P33 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A distinction that matters

A periodic clock contact is distinct from an on-delay or off-delay timer.
