Mouse Levers

	ENV-310W Ultra-Sensitive Mouse Lever
	This 0.625" (1.6 cm) wide stainless steel response lever is designed to protrude 0.375" (9.5 cm) into the mouse test chamber 7/8" (2.2 cm) above the grid floor. By breaking a photobeam instead of depressing a mechanical switch, the force required has been reduced to as little as two grams. This unit includes an infrared light source and detector and 28 V DC control. < back to top>

ENV-312W
Retractable Ultra-Sensitive Lever

This lever is mounted to a ½ size panel and features a stepper motor drive with the same response paddle and resistance-free photobeam actuator as the ENV-310W. The 0.625" (1.6 cm) wide stainless steel response lever protrudes 0.375" (9.5 cm) into the test chamber when 28 V DC is applies, and quickly and smoothly retracted from the chamber when the ground is removed. This lever is factory installed 0.878" (2.2 cm) above the grid floor; however, this distance may be increased with standard spacer panels.
