The 1597D5MTCKO is an Italtronic terminal insert with punch-out holes for DIN 5 enclosures in the 1597DM Series. With punch-outs, installers open only the terminal positions a build requires, which makes it a flexible cover for OEM products made in several variants. The series accessory table lists it for DIN 5, and the DIN 5 top-cover drawing includes it among the accessories for the grey Module 5 enclosure.

It is made from PC-ABS with a UL94 V-0 flame rating and measures 3.43 in x 0.54 in x 0.79 in (87 mm x 14 mm x 20 mm). Shipping weight is 0.01 lbs (0.00 kg), and it is RoHS and REACH compliant.

DIN group numbers in the 1597DM range refer to the number of terminals on each side of the enclosure. The DIN 5 terminal-cover family also includes the blank closed 1597D5MTC and the pre-holed 1597D5MTC6, both the same size. Hammond notes that some accessories are not compatible with all enclosures in a DIN size group and recommends checking the enclosure drawing to confirm compatibility.

The 1597D5MTCKO suits panel builders and engineers housing printed circuit boards and terminal blocks on standard 35mm DIN rail. Some chemicals can damage or weaken plastic, so check the manufacturer's Chemical Resistance Statement before using solvents, thread-locking compounds or cutting fluids near the part.
