Triggering: innovative dual-use sensor
Triggering must be safe and reliable under any condition. Systems that may freeze, get soiled or may be damaged by rodents are therefore not suitable. Also are pure pull-off solutions in which the magnet is ripped from the housing of the sensors is often not ideal, since this approach severely limits possible mounting position of the sensor (on the one hand the wire/cable should be kept as short as possible so that it is not trapped/jammed but on the other hand the sensor should be kept hidden). Nevertheless, pull-off solutions are often easier to install inside concrete pipe traps compared to solutions with proximity switches, which however, are often more suitable for many other trap types.
To merge these requirements in the best possible way TRAPMASTER utilizes an innovative dual-use triggering solution, which can be used both as a non-contact proximity switch (particularly suitable for wooden box traps) as well as a pull-off magnet (suitable for many concrete pipe traps).
The sensor unit is made of a waterproof aluminium cylinder (proximity switch) and a magnet. The proximity switch can only be used in the front half of the cylinder. If the magnet is located close enough to the proximity switch (non-contact with up to 2 cm distance or pinned), the switch closes. If the magnet moves away from the proximity switch when the trap doors close, the trap alert triggers an alarm.
The sensor can be used in two ways:
|As a non-contact proximity switch||As a pull-off magnet|
Trap closed (alarm triggered):
The cable is protected against rodent gnawing and biting. In any case if the cable is somehow damaged the trap alert system TRAPMASTER evaluates this as a release and triggers a desired (false) alarm.
