Circuit Boards and Sensor/Initiator Circuitry

Our electronic engineer manufactures about 20 different circuit boards. They contain sensors that detect change, or have timing delay and arming components. All are functional. Batteries are supplied.

Some examples are: lights-on, lights-off, active infra-red, passive infra-red, temperature rising, temperature falling, acoustic, x-ray initiated, proximity, humidity, time delay, etc.

Customers can also purchase these circuit boards mounted as a group on a display board, or in a Pelican carrying case.

Many have adjustable sensitivity, and a built-in automatic reset delay function, that is also adjustable.

Circuit Boards and Sensor/Initiator Circuitry

TEMPERATURE SENSITIVE RISE
Order Sku: ITA-107
Temperature sensitive Rise. Demonstrates that a rise in temperature can be used to initiate an IED. Device is connected to relay and uses two power sources.

TEMPERATURE SENSITIVE DROP
Order Sku: ITA-107A
Temperature sensitive Drop. Demonstrates that a drop in temperature can initiate an IED. Can be used in refrigerators and air conditioners.

SMOKE / DUST SENSITIVE IED
Order Sku: ITA-108
In operation, smoke or dust particles blown into the sensing chamber, cause a change in resistance. This is then translated by circuitry to output a detonating signal.

ACOUSTIC IED - SOUND LEVEL CHANGE
Order Sku: ITA-109
Device will detect a sharp change in sound and then initiate an IED.

Quantity
LIGHT LEVEL RISING - LIGHT SENSITIVE IED
Order Sku: ITA-110
Operates on the change in light intensity. Unit uses a light-sensitive photocell which produces a constant electrical resistance.

When light intensity is increased, resistance is changed and the detonator is initiated.

Price: $225.00
Quantity
LIGHT INTENSITY FALLING
Order Sku: ITA-111
Light intensity falling. Operates in same manner as ITA-110; however, the unit uses a different photocell and the logic unit is wired to sense change in resistance through a drop in light intensity

LIGHT LEVEL FALLING - LIGHT SENSITIVE IED
Order Sku: ITA-111
In ITA-111, the circuitry is designed so that it triggers when the circuit board (and improvised explosive device) are moved from a location where the light is bright, to an area of reduced or subdued light, shadow or darkness. The light level drop can be set using the two sensitivity settings. They have been factory set for normal room light at our location but may have to be reset by you. It is recommended that you make a sketch of the adjusting screw slot position on each of the two potentiometers (variable resistors) before any adjustment is made. Otherwise, you may have trouble returning to the factory setting.

INFRA-RED LIGHT SENSITIVE
Order Sku: ITA-112
Infra-red light sensitive. Contains special photocell particularly sensitive to infra-red light.
Note: This device works particularly well with infra-red output sources, but it also functions acceptably with many types of visible light.

Quantity
PASSIVE INFRA-RED SENSOR IED
Order Sku: ITA-112A
Designed to initiate a detonator when the room being monitored is entered. This device senses heat movements, changes.

CIRCUITRY DESIGNED TO DETECT AND TRIGGER ON A PULSED BEAM OF A PORTABLE X-RAY UNIT
Order Sku: ITA-113
X-Ray initiated. Circuitry designed to detect and trigger on as little as 1 pulse from a pulsed beam of a portable x-ray unit. Contained in a Samsonite attache case. Sold only to law enforcement and military E.O.D. agencies.

Quantity
HUMIDITY SENSOR
Order Sku: ITA-116
Humidity sensor. Uses commercial humidity sensor and is designed to initiate detonator as relative humidity changes.

Price: Request Quote
Quantity
PROXIMITY/TOUCH INITIATED
Order Sku: ITA-127A
Proximity/Touch initiated. Uses dual oscillator, very sensitively balanced magnetic field-emitted insulated wire.
