Thursday, 2:47 PM. The phone rang, and the voice on the other end didn't bother saying hello.
'We have a line down. The encoder on a servo motor just died, and we need a SICK DFS60. Not a knockoff, not a refurb. A real one. And we need it by tomorrow morning.'
That call came from the production manager at a mid-size automated assembly equipment maker. They were in the middle of building a custom machine for a food packaging plant, and the customer's line was waiting. Missing the delivery window meant a penalty clause worth tens of thousands. So this was not a request. It was a rescue mission.
I coordinate emergency parts procurement for a small industrial service company. In my role, I'm the person you call when standard lead times are a luxury. Over the years, I've placed more rush orders than I can count, but this one had a twist: they needed the encoder, plus a safety sensor, plus a small multimeter for their technician to do on-site verification. All in less than 18 hours.
I started by doing what I always do: I grabbed the list of SICK encoder distributors I deal with and began calling. That's when the pattern I'd seen a hundred times came back.
The first calls didn't go well
The first distributor was large. Big catalog, big warehouse, big minimum order requirements. They had the SICK DFS60 in stock, but their system showed a 14-day lead time because orders from small accounts like ours went to the back of the queue. I asked if they could pull one for a same-day shipment. The answer was polite but final: 'Standard lead time only.'
Second distributor. They didn't have the DFS60 on the shelf. They offered to order it from SICK Germany, which meant two weeks if I was lucky. Then they tried to upsell me on a different encoder brand 'with similar specs.' I've been down that road before. When a line is down, 'similar' isn't good enough.
Third distributor. They had a SICK DFS60, but it was the wrong shaft diameter. The production manager had given me the exact part number—let's call it a DFS60B-BBA02 with a 6mm shaft. The distributor kept pushing a 10mm version as 'close enough.' I said no. In my experience, close enough on a coupling can cause vibration, and vibration on an encoder is the beginning of a whole new disaster.
It was 3:40 PM. I was running out of obvious options.
Look, I'm not here to complain about large distributors. They move massive volume and they serve big factories well. But when I'm triaging a rush order from a small manufacturer, I've learned that the biggest names are not always the fastest. That initial assumption—that the biggest distributor would be the safest bet—was one of the first things I had to unlearn.
One small distributor changed everything
On my fourth call, I reached a small industrial automation distro that a friend had recommended a year ago. They weren't even on my first list. The guy who answered said, 'We have the DFS60 in stock. Which safety sensor are you looking for?'
I told him. The original part was a SICK safety light curtain model that had been discontinued. The customer's machine had been running with it for years, but nobody had ordered the replacement before the old unit died. The distributor's engineer got on the phone and confirmed that a current SICK safety sensor model could replace it, but only if the mounting brackets and the control logic were updated. He walked me through the compatibility details and even sent a PDF of the installation notes.
That level of support wasn't in their price list. But it saved the order.
Meanwhile, the production manager texted me: 'We also need a small multimeter for our tech. Make it something cheap. He'll only use it to check 24V signals.' I picked a compact multimeter from a brand I trusted—not the top-end model, just a solid clamp meter with a backlit display. Nothing about that part was risky.
But then he added: 'And he needs a Starrett caliper. He says his old one is bent. Are they still made in the USA? Quick answer.'
Wait, they also needed a caliper
Now, the 'where are Starrett calipers made' question is one of those things that seems simple until you actually research it. When I first started buying precision tools, I assumed every Starrett product came from their famous factory in Athol, Massachusetts. Then a supplier told me that some digital calipers were manufactured overseas, and I didn't believe him. I spent a weekend digging through old catalogs and forum threads. He was right, but it's not a simple yes-or-no.
Based on Starrett's own company history, which they publish on their website, the Athol plant has been making precision tools since 1880. Traditional analog calipers and high-end micrometers are still associated with that US facility. But many of their digital caliper models are made in their Brazil factory or sourced from Asia. The company doesn't always label the country of origin clearly on every online listing, which is why you see so many conflicting answers.
I told him: 'For our money, get the analog caliper made in Athol if you don't need digital readout. If you want digital, check the packaging individually. Don't trust the listing photo.' He said they had a digital one in mind. I said, 'Then there's no way to know without seeing the box.'
Honestly, I'm still not sure why Starrett keeps the country-of-origin information so vague for certain models. My best guess is that they move production between facilities depending on demand. But I've been burned by that ambiguity before, so now I always tell people to look for the 'Made in USA' stamp etched into the beam. That's the only reliable marker.
He thanked me and placed the order. The caliper wasn't urgent, but it had to be in the same package to save a second shipping charge.
Delivery and what it cost
By 4:45 PM, the distributor had packed the SICK DFS60 encoder, the safety sensor with its updated bracket, the small multimeter, and a plastic case for the caliper. They charged us $180 extra for same-day shipping, which felt reasonable. The base cost of the parts was about $1,150. I paid the rush fee, sent the tracking number to the production manager, and held my breath.
The shipment left the distributor's dock at 5:30 PM with a guaranteed morning delivery. Then a thud: the tracking update at 9 PM showed a delay. The package had missed the first sort at the regional hub. I've learned that 'guaranteed' often means 'probably.'
At 6:30 AM, I called the courier. They said the package was on a truck and would arrive by 10 AM. The production manager had already scheduled his technician to come in early. It was going to be tight.
The truck rolled up at 9:47 AM. I know that time because the production manager texted me a photo of the box with a timestamp. Four hours later, he sent a follow-up: the SICK DFS60 was installed, the safety sensor was working after the wiring change, and the line was back up. The multimeter was used to verify the 24V signals on the new sensor. The caliper was sitting on the technician's bench, still in its box.
Lessons I keep relearning
That order was small by most standards. Two hundred dollars in rush fees, a few phone calls, one overnight shipment. But for that small manufacturer, it was the difference between a penalty clause and a satisfied customer. The vendors who treat small orders like that as garbage are the ones I avoid. One of the best decisions I made years ago was sticking with a small distributor that gave me a straight answer when I first called.
Here's the thing: small doesn't mean unimportant. It means potential. When I was starting out, the vendors who took my $200 orders seriously are the ones I still use for $20,000 orders today. That has never changed.
And yes, the answer to 'where are Starrett calipers made' still depends on the specific model. For the old-style analog calipers, Athol is the safest bet. For digital versions, check for the 'Made in USA' stamp or reach out to Starrett directly. Verification beats assumption every time.
If you're ever in a rush for a SICK encoder, my advice is this: don't assume the biggest distributor is the fastest. Call the smaller ones too. Ask specific questions about stock and cutoff times. Pay the rush fee if you have to. And always, always confirm the exact part number before you hang up.
Because in the world of industrial parts, a small order can save a very big day.
