For PLC expansion modules with limited installation space (mounting pitch of 15mm), what connector should be selected?

Q: For PLC expansion modules with limited installation space (mounting pitch of 15mm), what connector should be selected?

A: Choose the M8 miniature series connectors (width <10mm), which are only 60% the size of ordinary M12 connectors and can be adapted to dense installation with a 15mm pitch. With 4~8 pins, they cover digital and analog signal transmission, and have a plugging force of <10N, facilitating stacked expansion of modules. In addition, the IP65 protection rating resists workshop dust.
