Small control unit for the monitoring of sensing strips in less dangerous applications. It fulfils safety category 1 which means that it may only be used in applications in which the risk of injury is only for slight, normally reversible injuries. If there is any doubt select one of the control units on the following pages. A low current is transmitted from the unit's connectors (Z1 & Z2) through the sensing strip, and a closed circuit is formed via a resistor (8.2 kΩ). The control unit output cuts the power if anyone/anything presses the sensing strip and also following a short-circuit or open circuit.

A few pictures from our recent team day (& night!) in Dublin City. A great day where we welcomed some of the OEM Sweden team also.
We recently had an incredible team building day at Croke Park where we had inspirational talks from Mark Donovan and also Niall Breslin, who talked about the excellent work his charity A Lust For Life.
Our partners and friends from OEM Automatic AB Sweden attended also. Great to show them a piece of Irish history.
Thanks to all involved and also to our amazing team for their hard work and dedication 💪
