Product description

The light curtains monitor a defined area using multiple invisible infrared light beams. The curtain photoelectric sensors consist of a transmitter and a receiver housed in a slim anodized aluminum profile, along with an external control unit. They operate on the principle of evaluating each individual beam, with detection handled by the external control unit. This allows for complex measurement tasks, and the control unit activates the corresponding outputs as well as digital data transmission.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks

Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure. The kind of faults that are frustrating to trace and expensive to fix.
Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
