Application Scenario:

Material feeding: Manually pour bulk oil seals (or directly receive finished products from the production line) into the storage hopper. A linear feeder at the bottom of the hopper delivers bulk oil seals to the spiral vibratory feeder. A sensor must be installed above the vibrating bowl to detect whether oil seals inside are used up.

Solution:

Choose HEYI’s MH Series –

One-piece inductive proximity sensors deliver outstanding metal detection performance. The integrated design enables easy installation and replacement, adapting to various on-site installation spaces.

Application Scenario:

Packaging film feeding: Roll film is stretched by a traction mechanism and fed to the cutting equipment. The bottom traction mechanism must reciprocate within set limit positions to avoid out-of-position movement that causes cutting deviation and packaging material waste.

Solution:

Choose HEYI’s UE-45/25 Series –

Slot-type photoelectric sensors with a slot width of only 5 mm meet high-precision positioning requirements. Compact in size, highly immune to interference, and highly stable, they are ideal for installation in compact packaging equipment.

Application Scenario:

Packaging film feeding: Roll film is continuously pulled and stretched during feeding. A sensor must promptly detect the "no film" status when the roll is nearly exhausted to alert operators for material replenishment, preventing equipment downtime or incomplete packaging due to material shortage.

Solution:

Choose HEYI’s FM-E31 Series –

High-speed digital fiber optic sensor, paired with FN-T064(R) through-beam fiber.

Highly stable and cost-effective, suitable for small-space detection.

Features automatic light gain, counting, zero drift, percentage display, light interference resistance, area detection, rising/falling edge switching, DTM, NO/NC switching, and time delay, flexibly adapting to diverse working conditions.

Four operating modes available: MEGA / SUPER / FINE / HIGH SPEED.

Application Scenario:

Packaging film cutting: When the composite film reaches the cutting position via the stretching mechanism, a sensor must accurately detect film in-place status and send a trigger signal to the cutting unit, ensuring accurate cutting position and neat cuts.

Solution:

Choose HEYI’s ZL-GR10MN –

Retro-reflective photoelectric sensor

Detection distance up to 10 m for flexible installation.

1 ms high-speed response time, suitable for detecting rapidly passing packaging film.

IP65 protection rating, resistant to dust and mild moisture in packaging environments.

Application Scenario:

Material sorting and feeding: After the vibrating bowl sorts and delivers oil seals to the transfer unit, a sensor detects oil seal in-place status, signals the sorting mechanism to close the gate, and the transfer unit moves oil seals above the packaging bag.

Solution:

Choose HEYI’s ZL-BG30 Series –

Square laser photoelectric sensor with background suppression

Background suppression eliminates interference from workpiece materials and background colors.

Laser light source with small spot enables precise detection of small objects.

Strong anti-interference and high stability, adapting to complex electromagnetic environments near vibrating bowls.

Small blind zone (only 2–3 mm) with flexible installation distance for easy on-site commissioning.

Application Scenario:

Finished product output: Packaged oil seals are conveyed to the next process via a belt conveyor. Accurate counting is required for production statistics, inventory management, and to avoid under- or over-packing.

Solution:

Choose HEYI’s UE-13D / UE-13L –

Ultra-thin through-beam photoelectric sensors

Dual-color indicator lights allow output status observation from multiple angles for easy commissioning.

Ultra-slim and compact, requiring minimal installation space and fitting into compact conveyor structures.

Excellent resistance to complex environmental interference, ensuring stable operation in dusty and vibrating conditions.

1 ms response time enables accurate detection of high-speed moving finished packages for reliable counting.
