A triangular bonding pattern — three joints that all need to cure together rather than in sequence — creates a specific fixturing problem: indexing the part between three separate single-point cure cycles adds mechanical complexity and cycle time that a lamp with three matched outputs removes entirely.
Three Tips, One Trigger Event
The Incure S20-3P is the three-pole configuration in the Incure S20™ family, delivering matched UV irradiance to three lightguide tips simultaneously from a single trigger. All three cure points fire in the same exposure event — no indexing, no re-fixturing between points. That makes the S20-3P a direct fit for triangular joint layouts, connector potting operations, and any three-point assembly where every point needs to cure together rather than sequentially.
Cycle-Time Impact of Simultaneous Three-Point Cure
Curing three bond points in one exposure rather than three sequential single-point cycles reduces the cure portion of cycle time by up to two-thirds versus sequential curing with a single-output lamp. On a fixture running a triangular or three-point pattern repeatedly, that reduction compounds across every unit produced — the time saved per part scales directly with production volume, which is why three-point simultaneous cure tends to justify itself quickly on higher-throughput lines even though the multi-pole hardware costs more upfront than a single-output unit.
Matched Output Across All Three Points
Equal power distribution to each of the three lightguide outputs ensures all three joints cure to the same degree in the same exposure — no variation in UV dose between points that could otherwise leave one joint under-cured relative to the other two. The S20-3P runs on the same 200 W mercury arc platform as every S20™ configuration, delivering broad-spectrum output from 300 to 550 nm that activates standard photoinitiator systems without adhesive reformulation. Output intensity is adjustable from 25% to 100%, with a programmable timer from 1 to 99 seconds. Available with Ø3 mm lightguide tips in standard lengths of 1 and 1.5 meters; UV protective safety goggles are included.
Physical Footprint for Multi-Guide Stations
The S20-3P controller shares the same 10.6″ × 8.7″ × 4.1″ dimensions and 6.0 lbs (2.7 kg) weight as every S20™ configuration — the added lightguide count doesn’t change the controller’s physical footprint, only the number of cable runs extending from it. On a bench station running three lightguides to a triangular fixture, planning cable routing so all three reach their cure points without crossing or interfering with part loading and unloading motion is worth reviewing during initial setup rather than after the fixture is in daily use.
Sizing the Fixture Around Three Fixed Points
Because the S20-3P’s three outputs are matched and fire together, fixture design should position all three cure points to arrive under their respective lightguide tips simultaneously — a fixture that can only present one or two points at a time doesn’t take advantage of the configuration’s core benefit. Reviewing the physical layout of the triangular pattern against the available Ø3 mm tip and cable-length options before finalizing fixture tooling avoids a mismatch discovered only after the equipment arrives.

Operating Conditions and Restart Cycle
The S20-3P shares the same operating envelope as every S20™ configuration: +10°C to +40°C ambient, 30–75% relative humidity during operation, 1-to-2-minute warm-up, and a 2-to-5-minute cooling period before restart, with dual filtered DC fans and an internal 65°C over-temperature shutdown. On a three-point fixture running high-frequency cycles rather than infrequent batches, the restart-cooling window is worth building into cycle-time planning up front — a lamp that needs to cool between triggers introduces a floor on achievable throughput that isn’t obvious from the timer’s 1-to-99-second range alone.
Confirming Genuine Simultaneity Is Needed
Three-point simultaneous cure is worth the multi-pole investment specifically when all three joints genuinely need to set together — for connector potting, for instance, curing all three anchor points in the same event prevents any one point from shifting slightly while the others are still curing. For applications where the three points could tolerate curing in sequence without a quality impact, a lower-pole-count unit run through three cycles may be a simpler and lower-cost fit; the S20-3P earns its place specifically when simultaneity itself is a process requirement, not just a throughput preference.
When to Step Up or Down From Three Poles
A layout with only one or two simultaneous cure points is better served by the Incure S20-1P or S20-2P configurations — splitting the lamp output across three tips when only two are actually used per cycle leaves capacity unused. A four-point pattern steps up to the S20-4P instead. Matching pole count to the genuine number of simultaneous cure points keeps per-tip intensity as high as the pattern allows.
For connector potting or multi-point assemblies also requiring precision fluid dispensing ahead of cure, the Incure Sniper™ precision dispensing needles line covers needle selection matched to the adhesive being dispensed at each of the three points.
