32.5mm (1.28") Dia. Cut-out

IP67 / NEMA 4X Protection

The EM32-1B is a 3½ digit LCD voltmeter which is designed to be panel mounted into a 32.5mm (1.28") diameter cut-out. The module features a metal bezel and rubber seal providing IP67/NEMA 4X protection to the front of the module when fitted into a panel and secured with the nut provided. The meter features 8mm digit height, selectable decimal points, auto-polarity, auto-zero, 200mV full scale reading and a very low current consumption. This product is designed so no soldering is required. Connection is via screw terminals, and options are selected via jumper links.

This is a popular part, normally stocked in high quantity and suitable for new designs.
