How to select between NPN and PNP outputs

Match with PLC input modules. NPN output connects to sink input; PNP output connects to source input

How to choose NO (Normally Open) and NC (Normally Closed)

NO: No output when no metal approaches; output activates when metal gets close. NC: Output is active when no metal approaches; output deactivates when metal gets close. Select according to equipment safety logic

What is the difference between 2 wire and 3 wire types

3 wire: Power supply, GND and signal lines. Load is connected to the signal terminal, widely used in applications. 2 wire: Sensor and load are connected in series with simple wiring. However, static leakage current exists, which may cause malfunctions for small size loads

What is the function of analog inductive proximity sensors

It outputs continuously varying voltage/current signals corresponding to metal distance. It enables rough distance measurement, instead of high precision ranging

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 inductive proximity sensor

It is based on the principle of electromagnetic induction. The internal oscillating coil generates an alternating magnetic field. When a metallic target approaches, eddy current losses occur on the metal surface, attenuating the oscillation amplitude. The sensor detects this amplitude variation and outputs a switching signal to achieve non contact detection of metal objects

Q:What is the detection distance

The Max detection distance relates to the sensor diameter: M8: 2mm; M12: 4mm; M18: 8mm; M30: 15mm

Q:What output types are available

NPN: NO NC, PNP: NO NC; some models support analog output

Q:How to distinguish between flush mountable and non flush mountable types

Flush mountable: Can be fully embedded into a metal base for installation. Non flush mountable: The sensing face must protrude from the metal surface; otherwise the detection distance will drop significantly

Q:What objects can be detected by inductive proximity sensors

Only metallic objects can be detected. Best performance is achieved with iron and steel. Copper, aluminum and stainless steel will reduce the actual detection distance
