High-density assembly fixtures with four bonding positions per part have historically meant one of two things: four separate spot-cure systems wired into the same cell, or a slow sequential cycle running one point at a time on a single-output lamp. Neither is efficient once volume climbs.
Four Simultaneous Cure Points, One Controller
The Incure S20-4P is the four-pole configuration in the Incure S20™ family, distributing the platform’s 200 W mercury arc output across four lightguide tips that fire simultaneously in a single trigger cycle — the maximum multi-point output available anywhere in the S20™ range. Four bond points cure in the same exposure time as one, making the S20-4P the highest-throughput configuration in the family for any fixture with four positions to cure per cycle.
One Lamp Replaces Four Independent Spot Systems
Consolidating four separate UV spot-curing systems into a single lamp, single controller, and one trigger event reduces capital equipment cost, cabinet wiring complexity, and process control programming overhead on high-density assembly fixtures. Instead of four units each needing their own power connection, trigger signal, and maintenance schedule, a production line running the S20-4P manages one piece of equipment that does the same job across four positions — a meaningful simplification on fixtures where panel space and cabinet real estate are already tight.
Matched Output Across All Four Tips
Equal power distribution to each of the four lightguide outputs ensures consistent UV dose at every cure point in the same trigger event, with no variation across the fixture between the four positions. The S20-4P runs on the same broad-spectrum 300–550 nm mercury arc output as every S20™ configuration, activating standard photoinitiator systems without requiring 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 from 1 to 2 meters; UV protective safety goggles are included.
Physical Footprint With Four Cable Runs
The S20-4P controller retains the same 10.6″ × 8.7″ × 4.1″ dimensions and 6.0 lbs (2.7 kg) weight as every S20™ configuration, but running four lightguides from a single unit means four separate cable paths to manage on the fixture side. On a dense four-position layout, planning cable routing so none of the four runs interferes with part loading, robotic motion, or the other three lightguides is worth doing early — a tangled or crossed cable arrangement on a high-cycle-rate fixture creates unnecessary wear and a recurring source of downtime for re-routing.
Throughput Planning for High-Volume Lines
Because splitting lamp output four ways reduces per-tip intensity relative to a single-output configuration, the S20-4P is the right fit specifically when a fixture genuinely presents four simultaneous cure points — not as a general-purpose high-throughput lamp for lower pole counts. On high-volume automated lines where four-position fixtures repeat continuously, the reduction in cabinet complexity and the elimination of indexing between sequential single-point cycles typically outweighs the reduced per-tip intensity, provided the adhesive and bond-line thickness don’t require the higher irradiance of a 1-Pole or 2-Pole configuration. Email Us with the joint thickness and fill level to confirm the S20-4P’s per-tip output is sufficient for the specific adhesive in use.
Operating Environment for High-Duty-Cycle Lines
The S20-4P operates within the same +10°C to +40°C, 30–75% relative humidity envelope as every S20™ configuration, with a 1-to-2-minute warm-up and a 2-to-5-minute cooling period before restart, managed by dual filtered DC fans with an internal 65°C over-temperature shutdown. On a high-density, high-volume fixture — exactly the kind of application the 4-Pole configuration is built for — the restart-cooling interval deserves explicit attention during throughput planning, since a line running near-continuous cycles benefits most from the S20-4P’s four-point consolidation only if the cooling window doesn’t become the limiting factor in overall cycle time.
Integrating Into Conveyor and Automated Cells
Four-position fixtures running the S20-4P are frequently part of a larger automated or conveyor-fed cell. For lines building continuous-flow production around this configuration, the Incure CDM™ UV conveyor covers lamp-head integration matched to line speed and part width, worth reviewing if the S20-4P’s four positions are destined for an inline rather than static-station layout.
Planning for Mercury Arc Bulb Replacement at High Duty Cycle
The S20-4P’s 200 W mercury arc lamp is rated above 2,000 hours typical — a figure worth tracking closely on a high-density, high-cycle-rate fixture, since a lamp running near-continuous four-point cure accumulates operating hours faster than an equivalent single-point station running the same wall-clock time. Scheduling bulb replacement proactively, ahead of a visible drop in output or an unplanned failure mid-shift, keeps the S20-4P’s throughput advantage from being undercut by unscheduled downtime. The Incure UV curing replacement bulbs guide covers selecting the correct replacement for the specific lamp model rather than matching on wattage alone.
