December 13, 2010 - Belden releases eight-pole M8 actuator/sensor connectors. These connectors, which fulfill all requirements for shock and vibration resistance, are being offered in two variants with molded 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 new eight-pole M8 actuator/sensor connector especially suitable for connecting optoelectronic sensors or safety switches of the kind used, for example, for monitoring safety doors on machines and systems.
The molded connectors, which can be used to connect sensors or actuators to switch cabinets or distribution boxes, have an open cable end, which ensures a high degree of flexibility in terms of the wiring. 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 molded bodies are made of thermoplastic polyurethane (TPU).
The cordsets, which are available either in polyvinyl chloride (PVC) or halogen-free polyurethane (PUR), have a cross-section of 0.25 mm2 and a length of 2, 5 or 10 meters. Other materials, cross sections and lengths can be supplied on request.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 simply 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).
