SICK 1052451 GSE6-N4112 NPN Through-beam Sensor Set

Technical Overview

The SICK GSE6-N4112 is a through-beam photoelectric sensor set with separate sender and receiver. Its 650 nm red PinPoint LED establishes a direct beam with 0–10 m sensing and 0–15 m maximum range. The NPN receiver supports selectable light/dark switching, response below 500 µs with resistive load and 1,000 Hz switching at a 1:1 light/dark ratio. There is no sensitivity adjustment. M8 four-pin male connectors provide power to both units and the receiver switching signal. The 10–30 V DC devices use ABS/PC housings, PMMA front screens, M3 mounting holes and IP67 protection. A stainless steel BEF-W100-A bracket, material 1.4301/304, is supplied.

NPN through-beam set with 0–10 m sensing, selectable light/dark switching, no sensitivity adjustment, M8 four-pin connections and a stainless steel bracket.

Industrial Applications

1. Counting separated opaque cartons

A conveyor can position the sender and receiver on opposite sides of a path carrying separated opaque cartons. Each carton interrupts the red beam and creates an input transition for external counting logic. Setup aligns both units, verifies the installed separation within the sensing range and tests carton gaps and transit timing against the documented response and switching-frequency conditions.

Problem Solved

A beam-interruption event helps external counting logic register separated cartons, using an opposed optical arrangement that does not require reflected light from each carton surface.

2. Monitoring opaque material continuity

An opaque feed strip can run through the beam between sender and receiver, interrupting light while material occupies the sensing point. A break or runout changes the received-light condition for external feed monitoring. Commissioning aligns both units and selects light/dark behavior, then verifies material coverage and the smallest required interruption under actual motion.

Problem Solved

A changed received-light condition helps external feed monitoring identify a break or runout, using an optical path across the actual material location and selected switching behavior.

Feed continuity Beam interruption External monitoring

3. Monitoring accumulation at a conveyor transfer

A transfer between conveyors can place the beam across the location that must clear before another load is released. External sequencing logic evaluates the receiver output duration to distinguish brief passage from sustained occupancy. Setup verifies alignment and coverage with representative loads and tests the selected light/dark behavior through the actual transfer sequence.

Problem Solved

A sustained beam interruption supplies external sequencing logic with an occupancy reference, helping coordinate upstream release when loads remain across the monitored conveyor transfer.
