content: Pretty much every power entry module out uses a rectangular profilehttps://www.digikey.com/en/products/detail/schurter-inc/6163-0004/2646990, that is fine when you have custom enclosure , but I often use COTS enclosures and modify them. I mostly use cord grips that use standard sheet metal punch sets diameters. But for power entry modules I have to cut and file a rectangular cutout and that is very time consuming. I'm looking for one that can be installed with jam nut and use standard enclosure punch out tools. Closest thing I've found ishttps://www.schurter.com/en/datasheet/4761but that does not use standard C13/C20 connection. So Anybody now of any jam nut style IEC PEMs a secondary option would be a PEM+compatible punch set

content: yea the issue finding a PEM that fit it near exactly most COTS punches I've found are several mm too big or small on at least one axis to fit well. and getting custom tooling made is big$$ a couple hundred for COTS punch is fine though it will pay for itself in 2 or 3 jobs but custom tooling is going to be couple grand between machining and heat treat

content: Another low cost and low effort option - make a trim plate out of PCB with the correct internal cutout for the connector, and a larger outer profile of a suitable shape, then mount that over a round hole in the case...and as a bonus, you also get any markings ( voltage/power rating etc.) printed for free

Alternatively, Bromac (Brook's Machine) might not be that expensive for something custom.https://bromac.biz/panel-punchesEdit: to be clear, this is not a round IEC inlet but rather the PEM/punch option the OP mentioned as a secondary option.

content: The Bulgin catalog shows many variations of IEC panel mount connectors, but every one requires a rectangular hole.

content: The Schurter S16 is installed with a large nut on the back, but it's just the connector, no fuse or switch.

content: yea bought one of those by mistake once they are not a standard IEC connector, some proprietary thing. so kinda pain to use since our shop standardize on zonit zlock c13/c19 cables some time ago

content: yea that looks pretty good i might consider buying that. did you have a method for finding that particular combo cause I would love to have option for both c13/14 and c19/20

content: Quote from: qwaarjet on February 05, 2025, 05:12:22 pmTo allow mounting of a standard IEC-type line filter input module (no switch or fuse), I ordered custom face plates fromhttps://sendcutsend.com/that have the rectangular hole and two holes for the mounting screws, to fit over a 1-3/16 inch diameter round hole in the panel. At quantity 25, they charged me $21.25 plus $12.96 shipping (total). Overall dimensions 1-1/2 by 2 inches. 5052-H32 aluminum, 0.040" thick. Should arrive next week.
