Electronics Manufacturer, Supplier & Sourcing Partner

Since 1990, we have supplied professional electronic products to businesses in the UK and international markets, combining practical technical knowledge with established manufacturing and supply-chain relationships.

Our product range includes PSTN and GSM auto diallers, 4G GSM alarm diallers, 433MHz and 868MHz radio transmitters and receivers, wireless security products and Netzhome WiFi sensors and smart devices. Keystone’s current range includes the AD06 GSM Voice and Text Auto Dialler alongside its PSTN dialler products.

We work with distributors, wholesalers, security specialists, OEM manufacturers, catalogue companies and online retailers looking for dependable electronic products at competitive prices.

Our experience goes beyond supplying products from a catalogue.

We help customers identify, source and develop electronic products to meet specific technical, commercial and application requirements. Where an existing product is suitable, we can supply from our established range. Where a standard solution does not meet the requirement, we can also assist with sourcing or developing bespoke electronic products through our network of trusted manufacturing partners.

This approach helps customers access specialist products that may be difficult to obtain through conventional UK distribution channels, while simplifying the process of sourcing from overseas manufacturers.

Our core range covers products developed for practical, real-world applications.

This includes the AD06 GSM auto dialler and GSM alarm communicator, PSTN voice diallers, low-cost 433MHz and 868MHz transmitters and receivers, and connected WiFi monitoring devices.

Our Netzhome range includes motion, temperature, shock, water leakage, panic and universal WiFi sensors, with alerts delivered to smartphones and tablets through the accompanying app.

Reliability, compatibility and clear technical information are important when electronic products are used in security, monitoring and communication applications. 

We therefore take a practical approach to product selection and supply, helping customers understand specifications and identify products suited to their intended application.

From an individual wireless receiver or sensor to ongoing product supply for distributors and OEM customers, we aim to make sourcing specialist electronics straightforward.

From our UK base, Keystone Electronics works with customers and distribution partners internationally. The company maintains an international distributor network alongside its UK operation, providing a central point for product information, technical enquiries and supply. 

Whether you are looking for a 4G GSM alarm dialler, wireless transmitter or receiver, Netzhome WiFi sensor, security device or bespoke electronic product, Keystone Electronics can help you find a practical and cost-effective solution.
