Abstract: An actuator capable of preventing a malfunction of the actuator due to iron powder contained in working fluid and the abrasion of a cylinder and a piston is provided. The actuator includes a cylinder (51) extending in a vertical direction and having an opening (51a), a piston (52) moving inside the cylinder (51), and a stroke sensor (53) that detects a position of the piston (52). The stroke sensor (53) includes a member to be detected (53b) which is a magnet, and a sensor (53c) which detects the member to be detected (53b). The member to be detected (53b) is located below a lower edge portion (51a1) of the opening (51a).

Abstract: An actuator having sufficiently high detection accuracy while having a simple configuration is provided. An actuator includes a cylinder (51), a piston (52) that moves inside the cylinder (51), a stroke sensor (53) that detects a position of the piston (52), an edge portion (51a1) that restricts rotation to one side, and a restriction protrusion (51b) that restricts rotation to the other side. The amount of rotation allowed by the edge portion (51a1) is larger than the amount of rotation allowed by the restriction protrusion (51b). A center of a sensor (53c) of the stroke sensor (53) is shifted to one side from a center of a member to be detected (53b) fixed to the piston (52).

Abstract: A forklift fork grabber mechanism is provided for clamping forks to a load by applying tensile or compressive force between a forklift attachment and the forks using a binder, bolts, motor, latch, or other means.

Abstract: Disclosed herein are apparatus and methods for linear actuators that can deliver strokes and forces at different values. The linear actuators include both multi-coil and single-coil actuator designs. The linear actuators include a controller that is removably or permanently coupled to a piston assembly having any number of coils. An encoder may also be removably or permanently coupled to the piston assembly. The piston assembly, controller and encoder move as one unit during actuation of the linear actuator.

Abstract: A gripping device for mechanical fasteners, such as rivets, screws, bolts, and similar fasteners, and a robot effector employing such a device. The device includes a housing and a pair of jaws arranged on a holder. The pair of jaws is adapted to grip a mechanical fastener therebetween. The holder is rotatable inside of the housing and the jaws allow a self-centering of a gripped mechanical fastener.

Abstract: The invention relates to a magnet retention member (1) which can be fitted to a wall (28) of a locking sleeve (27) for a gear mechanism, a locking sleeve (27) and a position sensor arrangement (37) for a gear mechanism. In order to be able to produce the position sensor arrangement (37) with the magnet retention member (1) and/or the locking sleeve (27) in the most cost-effective manner possible, there is provision according to the invention for the magnet retention member (1) to have a retention slot (4) for receiving a wall (28) of the locking sleeve (27), which is flanked by retention arms (2, 3) of the magnet retention member (1), the wall (28) having a securing portion (32) for the magnet retention member (1) and the position sensor (37) having a magnet retention member (1) according to the invention and/or a locking sleeve (27) according to the invention.

Abstract: An electronic device, comprising” a housing; a magnetic element guideway, the guideway enables positioning of an accommodated magnetic element in at least two magnetic element positions relative to the housing. A control and evaluation circuit in a chamber with two Hall sensors for registering at least one component of a first local magnetic and for providing, a signal, which depends on the local magnetic field registered at the first site. The two Hall sensors have relative to the housing a defined position, wherein the control circuit is suitable based on the signals to detect whether a magnetic element is present in the gateway, and in case yes, based on at least one of the two signals, to detect whether the magnetic element is located in the first defined magnetic element position or has been moved from this position.
