Three things that decide whether a radar sensor fits inside your product — solved.
It reads to ±2 mm across its full 0.05–10 m range, so your finished device reports level with the precision engineers trust for batching, inventory and process control.
Ø32 mm body with an M32×1.5 thread — the same size as a cable gland, not an instrument. It drops straight into tight enclosures and thin-wall housings where a full-size radar has no room.
Supplied as a bare module with full developer docs — dimension drawing, wiring diagram, protocol and sample code. Build it behind your own M32 opening and ship under your name; we stay your sensor supplier.
Real hardware, real dimensions, real integration files — not stock renders.

Get the dimension drawing, wiring diagram, protocol documentation and sample code for easy system integration.
TTL UART by default, with RS-485 also available. The communication protocol is customizable — Modbus or a simple text protocol — so it drops into most MCU or PLC designs without a bridge board.
The body is Ø32 mm with an M32×1.5 thread — the same size as a cable gland. Cut an M32 hole in your housing, screw the module in from the outside, and the finished device ships under your own brand.
