Magnetic door switch, NC, compact, outdoor

A magnetic switch monitors whether a wicket gate or door is closed. It is most often used with a sliding gate that passes in front of the pedestrian gate when opening. The switch is wired to the operator's safety input: if the pedestrian gate is open, the operator does not start the gate or stops it.

How it works

The switch is of the NC type (normally closed contact). While 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 input for safety devices, in the same way as photocells with an NC contact.

Installation

• Dimensions – the switch and magnet each measure 15 × 8 × 32 mm, so they also fit a narrow pedestrian gate profile.
• Fixing – Ø 3 mm mounting holes at 20 mm centres. Put the switch on the post and the magnet on the pedestrian gate leaf.
• Wiring – the input setting is described in the instructions for the operator's control unit.

A larger 106 mm switch is the NC magnetic switch. Operators can be found in the category sliding gate operators. Send questions to eshop@saver.sk.
