Well, it seems that at least for some handheld radios you will need to gently cut a little rubber around jack cable connectors to make it fit into the socket.

This cable allows you to connect PLXDigi/PLXTracker to radios using Icom handheld standard.

This cable version allows you to connect DS18B20/DS18S20 thermometer directly to RS-485/A+ input. Telemetry module is no longer necessary for temperature measurement.

Cable length: around 50-60 cm.
