At K 2016 last month, RJG Inc., Traverse City, Mich., introduced what it says is the world’s smallest strain-gauge cavity-pressure sensor. The new 6-mm sensor, which is placed under an ejector pin, is designed for high-cavitation molds with small, tightly packed pins. Its sensor head matches the dimensions and installation pocket of RJG’s piezoelectric 9211 button but costs about 20% less and is easier to use. That’s because, unlike the piezo sensor, the new button’s connector cables can be bent and folded without damage, making them easier to maneuver around obstacles.
The new sensor works in conjunction with RJG’s eDart monitoring system. Two sensor models are offered, one rated to 50 lb for use with ejector pins up to 2 mm diam., and one rated to 250 lb for pins up to 4.5 mm diam.
