Introduction
The tm2G gated timer is used to give precise
rejection of packaged or individual products.
The use of gating via a pack sensor ensures that the
rejection is independent of the position or size of the
metal contaminant within the product.
This timer type is suitable for reject devices which
include air-blast diverters, drop/lift flap diverters,
punch or pusher units etc.
