We come from a background where our Automotive customers, such as Pontiac Motors, back in 1976, required us to run encoder wiring right along side with 440 VAC motor wiring without a shield as they did not want to change the connector between the control cabinet and the machine. You see, we had just invented the PLS and were replacing the old rotary cam switch with a PLS. GM wanted the benefits of the advanced technology but not change their wiring. Our Autotech division designed a Resolver based PLS where you could run it right along with 440 VAC and withstand unimaginable inductive kicks. In fact, we ended up making the resolver wiring short circuit proof and capable of taking a direct 120 VAC hit.

All our products go through extensive noise testing and have the following ratings:
NEMA ICS 2-230 Showering Arc
ANSI C37, 90a-1974 SWC
Level C Chattering Relay Test
