Siemens 3SE5 232-0HD03 Mechanical Position Switch, Complete Unit, Plastic Enclosure, 31mm Width, Roller Plunger, 10mm Plastic Roller, Snap Action Contacts, Integrated, 1 NO + 1 NC Contacts

This Siemens 3SE5 232-0HD03 mechanical position switch comes as a complete unit with a 31 mm wide plastic enclosure, one NO and one NC snap action contact, and a roller plunger actuator, and is suitable for use in plant and building automation systems. The snap action normally-closed (NC) and normally-open (NO) contacts switch from closed to open and open to closed at the same time, regardless of the actuating speed, and the roller plunger forcibly opens the NC contacts for use in safety circuits. The roller plunger actuator can be rotated around the enclosure axis in increments of 22.5 degrees and has a 10 mm plastic roller. The actuator allows 3 mm of plunger travel past the switch activation point (overtravel) for greater tolerance when switching. This mechanical position switch conforms to the European Committee for Electrotechnical Standardization (CENELEC) EN 50047 standard for dimensions and mechanical data and the EN 50041 standard for quality assurance, and is suitable for use in applications in which there is lateral actuation and relatively long overtravel.SpecificationsPositive opening of NC contactsEN 60947-1Quality assuranceEN 50041Dimensions and mechanical dataEN 50047Degree of protectionIP65Dimensions*68 x 31 x33 mm (H x W x D)*H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Mechanical position and safety switches are used to make or break electrical connections as part of a plant or building automation system. The switch is composed of a contact block with two or more contacts, an enclosure for protection, and an actuator head for monitoring object movement. Switch contacts can be normally open or normally closed, and switch connections can be either quick or slow, according to the requirements of an application, and they can include status LEDs and connector sockets. Actuator head types include rounded and roller plungers, roller and angular roller levers, spring rods, twist levers and rod actuators with a twist actuator, and fork levers with a twist actuator. Position and safety switches are used in applications such as elevators, emergency exits, and as emergency shutoffs in industrial workplaces.Siemens manufactures electronic products for building automation, industrial drives, lighting, energy generation, medical equipment, and rail transportation. The company, founded in 1847 and headquartered in Germany, meets International Standards Organization (ISO) standards 14001, 9001 and TS 16949.
