MX150™ Sealed Connector System 3.50mm Pitch

The MX150™ high-performance Sealed Connector System offers a reduced package size, meets or exceeds USCAR-2 Class 3 requirements and is ideal for SAE and ISO-style wire in single and dual-row configurations up to 22.0A, supporting low-level signal and power applications for on-engine automotive to off-road construction equipment.

The MX150 Connector System consists of matte- and cable-sealed connectors and receptacles. This system is based upon the 1.50mm (.060") ISO blade-type terminal system, available in tin, gold or silver contact finishes, therefore eliminating the need to purchase, handle and crimp individual wire seals to lower applied cost.
This design has a single silicone-based seal with individual wire openings and a seal cap to protect, securely retain and provide strain relief to the seal, and features all-in- one plug and receptacle housings. Integral terminal position assurance (TPA) and optional connector position assurance (CPA) components eliminate time-consuming and costly assembly operations.
MX150 Panel-Mount Connectors ensure simplified and reliable mating and assembly while providing superior sealing and electrical performance in rugged automotive and nonautomotive applications. This wire-to-wire connection system requires no curing to seal the blade connector to the case and provides flexibility in printed circuit board location and orientation. It also has integrated screw holes for mounting the connector to the case. MX150 Panel-Mount Connectors are ideal for high-temperature environments and employ gasket-seal technology to meet industry-standard sealing requirements.
MX150 M3 Grip Terminals are designed to support 0.35 and 0.50mm2 wire sizes. The terminals are a temperature Class 3 (-40 to +125°C). Designed for automotive applications, the MX150 M3 Grip Terminals reduced package size is ideal for ISO wires.
