AI-Powered supplier vetting

SummaryG-TEK is an industrial equipment and instrumentation supplier with stated sales of up to 800,000 pieces or sets in 2019 across proximity switches, photoelectric sensors, light curtains, and laser radar. It offers broad customization, reported new products within the past year, and has documented procedures for finished-product inspection, supplier assessment, corrective actions, and complaint handling. Its certifications include ISO9001:2015, ISO45001:2018, ISO14001, and CE capability. The supplier has three production lines, but does not continuously reconcile production quantities for every batch or bulk run. Export experience is established, with 10 years of exporting and three experienced export staff, although overseas operational infrastructure is limited: no overseas warehouse, showroom, agent, or branch is reported. Financial information is only represented by year labels, without substantive performance evidence. No SDK or ODM service is available, and no OEM service for popular brands is reported.

Supplier typeThe stated business scope covers on-board equipment, instruments and meters, intelligent instruments, industrial automatic control systems, and intelligent vehicle-mounted devices. The company description also identifies product sales including proximity switches, photoelectric sensors, light curtains, and laser radar, supporting classification as an industrial equipment and automation-related supplier.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, together with CE product certification capability. These are explicit certification holdings or capabilities relevant to quality, occupational safety, environmental management, and product compliance.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and effective customer complaint handling. However, it reports no overseas warehouse, showroom, agent, or branch; this indicates established complaint-process capability but limited overseas service infrastructure.

R&D capabilityThe supplier reports that it introduced new products during the past year and emphasizes continuous technological innovation. It also supports extensive product customization, but has no available SDK and does not provide ODM services; overall innovation activity is evidenced, while platform-development and ODM capability are limited.

Production capacityThe company reported sales of up to 800,000 pieces or sets in 2019 and operates three production lines. It has standardized finished-product inspection instructions that are uniformly followed, but does not continuously reconcile quantities for every batch or bulk production run, creating a stated production-control weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad capability is reported in two slices, providing strong direct evidence of extensive customization support.

Product Q&A

Q:What is the working principle of the photoelectric sensor with reflector for doors

It is a retro reflective photoelectric sensor. The sensor emits an infrared light beam onto the square reflector, and the beam bounces back to the sensor's receiver. When the light beam is blocked by a person or object, the output state toggles to realize passage detection and safety protection.

Q:What is the light source type

Invisible infrared light. Some models with laser light soruce for convenient on site alignment adjustment with the reflector

Q:How to choose between retro reflective (square reflector) and through beam photoelectric sensors?

The retro reflective type only requires wiring on one side. The sensor is installed on one side of the door body, and a square reflector is mounted on the opposite side, enabling easy installation. It is suitable for automatic doors and high speed doors. The through beam type is preferred for long distance and high dust scenarios.

Q:How to select the specifications of the reflector

The farther the distance, the larger sized reflector should be selected; be sure to distinguish between ordinary reflectors and sunlight resistant reflectors; the reflective surface must face the sensor directly.

Q:Will multiple sets of door photoelectric sensors installed side by side interfere with each other?

Adjacent multiple sets are prone to optical crosstalk; Solutions: increase mounting spacing, offset angles, and select models with different modulation frequencies
