Magnetic door switch, NC, outdoor

The magnetic switch monitors whether a pedestrian gate or door is closed. It is most often used with a sliding gate that passes in front of a pedestrian gate when opening. The switch is connected to the operator's safety input: if the pedestrian gate is open, the operator will not start the gate or will stop it, so that it does not hit the open pedestrian gate leaf or a person.

How it works

The switch is of the NC type (normally closed contact). As long as the magnet is 1–3 cm from the switch, the contact is closed. When the pedestrian gate opens and the magnet moves away, the contact opens and the operator treats it as an obstacle. Connect the switch to the safety device input, in the same way as photocells with an NC contact.

Installation

• fix the switch (106 × 38 × 10 mm) to the post and the magnet (106 × 16 × 16 mm) to the pedestrian gate leaf,
• the steel housing and the cable in conduit withstand the weather and mechanical damage,
• wiring and input settings can be found in the operator control board instructions,
• a smaller switch measuring 15 × 8 × 32 mm is the compact NC magnetic switch.
