CJ1 Screwless I/O Units
Screwless – the reliable connection!
Screwless clamp technology drastically reduces wiring time, eliminates routine maintenance,
and ensures a very reliable connection. That’s why Omron now introduces a new range
of screwless I/O units for the CJ1 PLC series.
Advanced Industrial Automation
Designed and manufactured in Europe according
to Omron’s high quality standards, the CJ1 screwless
I/O units are an ideal alternative for panel makers and
machine builders who want to reduce installation time
and add an extra dimension in secure, reliable
connections for all their control wiring.
Versatile and reliable

Omron’s screwless I/O terminals accept a wide range of wires,
Individual wires are easy to attach and detach from the terminal

Connecting wires to conventional screw terminals requires a lot of work.
See why it makes sense to use Omron screwless I/O units for all your I/O!
