Home AccessoriesModular Electronics Accessories General Adapters

The General Adapters family includes a range of passive interface and signal-routing accessories designed to simplify connectivity between detectors, digitizers, logic modules and front-end electronics. These adapters provide mechanical and electrical conversion between different connector standards (header, Samtec, ERNI, LEMO, LVDS, NIM), enabling seamless integration of heterogeneous instrumentation within nuclear physics and radiation detection setups.

Optimized for signal integrity and robustness, these accessories support clock distribution, multi-board synchronization, channel splitting and detector interfacing across multiple CAEN digitizer and readout platforms.

Connector and signal adaptation
Convert between header, LVDS, NIM, Samtec and ERNI interfaces for flexible system integration.
Clock and sync distribution
Dedicated adapters for CLK-IN/CLK-OUT daisy-chain synchronization across digitizers.
Multi-channel routing
Channel splitters and header adapters for efficient signal fan-out and detector interfacing.
Compatibility with CAEN platforms
Designed for Series 1 and 2 digitizers, MCAs, peak-sensing ADCs and front-end electronics.
