Lumberg Automation eight-pole connector range

Belden has extended its Lumberg Automation range with what is claimed to be the world’s first eight-pole M8 actuator/sensor connectors. They fulfil all requirements for shock and vibration resistance and are being offered in two variants with moulded cables as well as in three field-attachable installation variants.

All variants are designed for a temperature range of between -25° and +80°C, and, when screwed together with the appropriate counterparts, meet the requirements of protection type IP67. Owing to the high contact density, up to eight signals can be transmitted with an external power supply, making the connector suitable for connecting optoelectronic sensors or safety switches of the kind used, for example, for monitoring safety doors on machines and systems.

The connectors, which can be used to connect sensors or actuators to switch cabinets or distribution boxes, have an open cable end, which ensures flexibility. The male connector (RSM 8-354/0.3 M) has a snap-in/threaded joint and the female connector (RKMV 8-354/2 M) has a self-locking threaded joint.

Both bodies are made of thermoplastic polyurethane. The cordsets, which are available either in PVC or halogen-free polyurethane, have a cross-section of 0.25 mm² and a length of 2, 5 or 10 m. Other materials, cross-sections and lengths can be supplied.

The receptacle connector RSMF 8/0.5 M with stranded wires and a solder contact potted with epoxy is attached, for example, to the front of switch cabinets or other equipment. Conversely, the RSMEDG 8, which is designed, for example, for installation in sensors, can be pressed in and connected by means of a snap-in/threaded joint.

An additional plug insert is available with the RSEM 8 for various sensor housings which already have an M8 thread and/or a snap-in joint. The housings of receptacle connectors are made of nickel-plated brass (RSMF 8/0.5 M and RSMEDG 8) or polyamide (RSEM 8).
