Product description

Compact and failsafe magnetic switch e. g. for the receiver system. Contactless switching with an external magnet through the aircraft fuselage wall. From the outside only the status LED is visible.

Mounting suggestions

DPSI Micro Systems can be switched on and off contactless with an external magnet through the model's fuselage wall or with the transmitter, so they can be fixed at the fuselage inner sidewall. The switching on and off process with the magnet works up to a distance of about 8mm (0.3in) from the DPSI Micro's surface through the fuselage wall. To see the LED from the outside a small hole with 5mm (0.2in) diameter can be drilled in the fuselage wall.

Sticking on the DPSI Micro system

The DPSI Micro can be sticked on with silicone directly on the fuselage's inner sidewall.

Screwing on the DPSI Micro system

The DPSI Micro can be screwed from the outside to the fuselage wall. The required holes can be drilled using the included drilling template.

Both screws can be feed through the drilling holes from the outside. The screws are positioning helps for the self-adhesive foam rubber, which can be used as vibration protection. It is pushed over the screws from inside and glued to the fuselage's sidewall.

The vibration protection is not mandatory, but advisable especially for engine models with higher possible vibrations. Possibly small fuselage unevenness is eliminated, too.

The DPSI Micro can be mounted with two included M3 screws. The screwing collars enlarge the area of support and inhibit in this way damage to the fuselage.

Don't tighten the screws too much, in order not to press the cellular rubber too extensively.

Switching on and off

For switching on the DPSI Micro MPS magnetic switch the included magnet must be placed over the switching on position (ON) for approx. 1 second. For switching off the DPSI Micro DualBat the magnet must be placed over the switching off position (OFF) for approx. 2 seconds. The switching on and off process works through the fuselage wall.

Safety note

The switching off process of DPSI works with a hall effect sensor. Hall effect sensors can be influenced by magnet fields. It is possible that the DPSI switches off when exposed to a very strong magent field (i.g. electric drive). Current-carrying cables generate a magnet field. So please run all cables which are carrying a high current (>100A) with a distance of at least 3cm (1.18in) from the DPSI.
