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 are the key parameters for light curtain selection

Protective height, Optical axis (beam) pitch, Detection range,Output signal type, Power supply voltage

Q:How to choose the optical axis pitch? Is smaller always better?

Smaller is not always better. 50mm : General commercial automatic doors, cost effective, detects palms and human bodies. Occasional false triggering caused by insects or flying debris.

Q:How to determine protective height? Is total light curtain length equal to protective height?

Protective height refers to the effective detection height covered by beams, not equal to the overall housing length of the light curtain.

Q:How to select output type?

Relay dry contact, NPN, PNP, OSSD safety output. Must be compatible with the door operator / elevator main board.

Q:what is the height of door light curtain

from 1m to 2.5m as per different door type
