How we work

Sensor solutions - engineered to meet your system requirements

Sensor Detection works as an extension of your engineering team — one partner that designs the sensor, electronics and firmware. Every product is built to the requirements of your application, backed by more than 100 combined years of sensor engineering.

Direct engineer-to-engineer technical support
Design input from connector selection through to production
Spares, service and multi-year pricing agreements
Minimal development lead timeExtensive range of solutions already designed and ready for manufacture.
Scalable manufacturingFrom prototype quantities to full production volumes.

Compliance by design

DESIGN PHILOSOPHY

Compliant parts chosen at the design stage

Every part on a bill of materials is selected by our own engineers and bought through franchised or manufacturer-approved channels, so its compliance record exists before the product or parts are built.

  • Supplier RoHS, REACH and CMRT declarations collected per part and held against the bill of materials
  • Sourced exclusively through franchised distribution or manufacturer-approved suppliers
  • Declarations of Conformity issued per product on request
  • Compliance data held in our own ERP, tied to live manufacturing records

Manufacturing quality - independently certified

MANUFACTURING & QUALITY

Zero-defect manufacturing philosophy

Defects are designed out rather than caught at the end — and every product is still 100% tested before it ships, with stock and sub-assembly managed to the same standard throughout.

  • Full product data pack change control
  • Stock management in our own ERP — built for our requirements
  • Long-standing supplier partnerships with component traceability
  • Automated test at board and sub-assembly level, all in the UK
  • Production staff trained and measured to the same standard
0 ZERO DEFECTS RIGHT FIRST TIME 01 TRACEABLE STOCK 02 100% TESTED 03 ROOT CAUSE ANALYSIS 04 ERROR PREVENTION 05 CONTINUOUS IMPROVEMENT 06 BUILD QUALITY IN CONTINUOUS IMPROVEMENT LOOP PREVENTION FEEDBACK · DEFECTS DESIGNED OUT MANUFACTURING PROCESS
