Multi-Display Pecking Key

Model 80130

 

A new unique pecking key with 4 x 4 programmable stimulus array.

 

This multi-display "pecking key" may be used for pigeons, primates or rodents.  The response key is designed to trigger a durable (100,000 activation life) microswitch with as little as 0.6 mm of movement and 50 cN of force. 

The 35 mm by 35 mm display area (approximately 1.4 in x 1.4 in) features a sixteen LED array that can display any of 16 shapes in 8 different colors. The eight colors are: Orange, Red, Green, Yellow, Blue, Lilac, Turquoise, and White. The standard shapes are a cross, forward slash, back slash, square, circle, small dot, vertical bar, horizontal bar, and ALL ON as well as the random shapes shown below.
