Roller direction is adjustable. Standard features include built-in shock absorbers for long life and magnetic pistons for activating externally mounted sensors when input signals are required for controllers. An optional latch feature (#2) locks the lever in alignment to the rod after the workpiece has pushed the lever through the shock absorber stroke. The mechanism releases when the rod fully retracts. An optional ball-chain retained lockout cap (#3) fits over the shock absorber to position the roller out of the conveyor stream.
