ASCO JOUCOMATIC NUMATICS introduces a series of ASCO explosion proof solenoid valves featuring an Ex-approved plug and socket connector system. The new HA connector enables the installation, maintenance, repair and servicing of solenoid valves to be carried out within a hazardous area, without the need to isolate the equipment. Because there is no need to obtain a hot work permit which can delay the start of work, a replacement device can be quickly installed keeping plant downtime to a minimum.
The HA connection system comprises a male socket and optional a female connector. Designed for safe and fast installation, the HA connector reduces the risk of operator errors and makes termination easier even under extreme conditions. No tools are required and the available termination methods include crimped or cage-type spring-tension terminals.
The plug and socket is according to IP66/IP68 and rated at up to 10 A. An EEx de compartment around the connection pins ensures reliable explosion protection to meet Zones 1, 2, 21 and 22 requirements during connection or disconnection. The risk of spurious exchanges between AC and DC applications is avoided by using a special pin configuration and coupling ring integrated into the plug body, guarantees the mechanical integrity of the connection.
ASCO exproof solenoid valves with the HA connection system are suitable for industrial applications where ease of installation, reduction in down time and plug-and-play are essential.
