View Photo of corroded connector. ## Overview A magnetically-operated electromechanical switch designed to close when exposed to a magnetic field. This reed switch features normally-open contacts that close in the presence of a magnetic field, housed in a hermetically sealed glass envelope filled with inert gas. It operates with low contact resistance, fast switching speeds, and long operational life in low-power DC circuits. Commonly used in security systems, position sensing, flow meters, level indicators, and proximity detection applications. Suitable for integration into control systems requiring reliable non-contact switching with environmental protection against dust and moisture. ## Function Operates as a magnetically actuated electrical switch utilizing reed contacts within a hermetically sealed glass envelope to detect the presence or proximity of a magnetic field. Designed for integration into fluid or pneumatic systems, it provides reliable on/off switching with minimal contact wear. Connects via lead wires or terminal pins to electronic control circuits, enabling position sensing, flow monitoring, or end-of-travel detection in OEM equipment, instrumentation panels, and automated control systems. Compatible with DC and low-voltage AC circuits, ensuring precise and repeatable switching in harsh or constrained environments. ## Platform The reed switch provides non-contacting switching for position sensing or limit detection. It operates on a simple magnetic field. The switch is packaged in a cylindrical housing and can be integrated into pneumatic cylinders. It connects via a 2-wire or 3-wire configuration, typically with a voltage range of 5-24VDC. Common applications include automation and process control systems. ## Application Utilized in industrial and automotive systems for position sensing, speed monitoring, and proximity detection, this reed switch operates within control panels or embedded sensor assemblies. It interfaces via low-voltage electrical connections to controllers or signal processors, providing reliable open/closed contact actuation in magnetic field detection scenarios. Commonly applied in safety interlocks, flow meters, security systems, and rotary encoders to detect the presence or movement of magnetic objects with minimal power consumption. ## Accessories Requires standard 2-wire electrical connection, typically 18-24 AWG stranded wire with environmental jacket. Mounts via M8 x 1.0 threaded barrel with 17mm hex nut. H6L6 designation indicates 6mm sensing distance with normally open contact configuration. Compatible with Parker pneumatic cylinders having external tie-rod or profile-mounted sensor slots. Connects to PLC digital input modules or relay circuits. Maximum switching capacity 10W resistive load at 200VDC or 0.5A at 200VDC. IP67 rated with polyamide housing. No special accessories required beyond mounting hardware and electrical termination. ## Interface Single-pole single-throw reed switch element; no integrated connectors or cables; designed for direct wiring into control circuitry. Electrical ratings typically up to 200 VAC and 24 VDC switching; terminal connections are standard wire leads or solder tabs depending on mounting. No mainframe, backplane, or chassis requirements. The designation H6L6 does not indicate added interfaces or options. ## Images - - - -
