If you spend time around presses, robots or fast conveyors, you already know this: safety light curtains are not just a line on the BOM. They decide how close your team dare to stand, how fast the machine can run, and if EHS will sign off or not.
When space is tight, compact safety light curtains are usually the first option. On NOWA GWIAZDA we group safety light curtains into clear families: Compact Safety Light Curtain, Front Ultra-Thin, General Use, Heavy Machine, High-Precision, Multi-Sided Access Protection, Waterproof and more. That makes picking much easier for machine builders and safety guys.
The real starting point is always risk level, not price or pretty housing.
Ask yourself one simple question:
If someone reaches in and the machine doesn’t stop, how bad it can be?
NEW STAR’s compact range is built exactly for this kind of duty. For example, the Kurtyna świetlna bezpieczeństwa DGD0810 is a Type 4 compact safety light curtain designed for perimeter and access guarding around hazardous points in factory automation.
Same idea with the Ręczny czujnik bezpieczeństwa DGD3210. It’s a high-resolution Type 4 compact safety light curtain aimed at point-of-operation guarding for hands and fingers, so it fits press brakes, small cutting stations, bending machines and other risky tooling zones.
If your risk assessment says “serious injury possible”, don’t try to save by shifting to lower grade devices. That usually ends with more paperwork and angry safety manager later.
You can split compact safety curtain jobs into two big buckets.
If you mix these two duties, you end up with wrong resolution, wrong mounting, and lots of nuisance trips that operators hate.
Once risk level is clear, the next filter in your compact safety curtains selection list is resolution and protection height.
Think in very simple terms: what exactly you want to detect, and how big is the opening?
From NEW STAR’s compact models:
Basic rule (yeah it’s not perfect, but works on most projects):
Compact curtains let you keep this resolution and just-enough height in a slim stick, so you don’t block visibility and don’t fight with the frame.
Space is the pain point on many machine frames. The drawing says “we have room”, then you go on site and real space is 22 mm plus some dust.
NEW STAR compact safety light curtains, like DGD0810, DGD1620, oraz DGD3210, all use a 22 × 30 mm cross-section, work on DC24 V, and keep response time within a fast few milliseconds range. Power draw stays low and all three have built-in short-circuit and over-voltage protection.
This makes life easier when you retrofit:
Map this to real lines and it becomes more clear:
This kind of setup is common in real factory, not only in brochure.
Most of your machines run in classic standard industrial environment: some dust, oil mist, maybe coolant splash, but not full wash-down.
For that kind of duty, the compact models DGD0810, DGD1620, oraz DGD3210 have:
That covers metalworking, plastics, 3C electronics, EV battery modules, automotive sub-assembly, woodworking and board processing, many logistics and warehousing tasks.
If you go into real wash-down, food, beverage or chemical duty, you switch to Wodoodporna kurtyna bezpieczeństwa or special housings. NEW STAR keeps these as a separate product line, so you don’t confuse one spec with another.
Sometimes the question is not “compact or big”, but from which side you want to save space.
Use compact when you hide it in the frame, use front ultra-thin when your door or glass panel is almost flush and every millimeter matters.
A lot of engineers are tired of “spaghetti safety” – separate safety relay, separate curtain, and too many wires.
The Sterownik kurtyny świetlnej bezpieczeństwa DGD1620 solves that by packing a Type 4 compact safety light curtain with integrated controller into one stick. Range is 1.6 m with 20 mm resolution and 300 mm protect height, so it fits area guarding and access control on packaging lines, robot loading stations and small machining cells.
You still get:
This makes new projects simpler and also helps when you do safety upgrade on old equipment. Wiring gets cleaner, and troubleshooting for maintenance guys is more straight forward.
Here’s a quick table that you can use as a small compact safety curtains selection list for common projects.
| Model | Category | Typical duty | Range | Rozdzielczość | Protect height | Housing | Stopień ochrony | Uwagi |
|---|---|---|---|---|---|---|---|---|
| Kurtyna świetlna bezpieczeństwa DGD0810 | Kompaktowa kurtyna świetlna bezpieczeństwa | Perimeter and access guarding near hazardous points on machines | Long enough for small cells and guarding doors | 10 mm | 70 mm | 22 × 30 mm | IP64 | Type 4, good for small windows, tools area and tight frames. |
| Sterownik kurtyny świetlnej bezpieczeństwa DGD1620 | Compact Safety Light Curtain with controller | Area guarding, access control on packaging, robot cells, conveyor in-feed | 1.6 m | 20 mm | 300 mm | 22 × 30 mm | IP64 | Type 4 with integrated controller, wiring is simpler for OEM and retrofit. |
| Ręczny czujnik bezpieczeństwa DGD3210 | Compact Safety Light Curtain (hand safety sensor) | Finger and hand protection at point-of-operation | 3.2 m | 10 mm | 310 mm | 22 × 30 mm | IP64 | High-resolution Type 4 for small access openings around tooling. |
You can add front ultra-thin models like Kurtyna podczerwieni DCBZ1240 or wholesale units like SWP2840 industrial light curtains ODM on top of this list when you need measurement, DWS dimensioning or special layouts.
Most of the time you’re not buying just one pair. You might be an equipment builder, automation integrator, EHS manager or production engineer who needs the same spec across many machines and maybe across different plants.
NEW STAR positions itself as a Kompleksowy producent czujników bezpieczeństwa do maszyn, supplying safety & measurement light curtains, laser scanners, safety mats, interlock switches, photoelectric and flow sensors, with OEM / ODM service from sample stage to mass production. For you this means:
So the best way to use a compact safety curtains selection list is simple:
If you’re not sure which model fits a press, a robot cell, a packaging in-feed or a DWS station, send your layout and rough risk info to the NEW STAR team. They work with OEM, integrators and safety people every day, and they can help you lock the right compact safety light curtain before you cut steel or change guarding.
