Circuit count, rated current, wire length, flange pattern and connector type can be tailored to your drawing. Tooling and samples are available before mass production, and each unit is 100% electrically tested (insulation resistance, dielectric strength, dynamic contact resistance) before packing.
Double lip O-rings with a grease reservoir keep water out even after shaft wear, and each unit is pressure tested at 1.5 times rated depth before packing.
Send your working speed, circuit count and installation space, and our engineers will confirm the right model within 24 hours. MOQ starts from 1 piece for samples.
