The Kanetec suite of small electromagnets, permanent-electro and spring-release magnetic grippers and holders is presented in Australia by Serpent and Dove Pty Ltd. In diameters from as small as 10 mm (depending on type) up to 100 mm or more, these magnetic grippers or holders can be used for applications for steel sheet pick-up or small component gripping or placing. The range includes standard electromagnets, permanent-electro and spring release options. Permanent-electros employ permanent magnet technology for pick up and holding and electric power only for release. Spring-release electromagnets feature an adjustable tension coil spring providing pressure to a pin that bears on the gripped surface so that release is immediate when current is switched off.
