Product Update: MX Sensing and Latching Contactor Options for 48Vdc RFQs

Sorint is highlighting MX series contactor references for buyers preparing 48Vdc high-current sourcing requests. The local product records include MXSB16BE and MXSB16CE sensing contactors rated at 600A - 48Vdc, plus MXSL15BE and MXSL15CE latching contactors rated at 350A - 48Vdc. For procurement teams comparing DC contactor options across battery equipment, industrial power panels and service programs, these records give a practical starting point for RFQ review.

This product update is written for purchasing teams that need clearer line-item information before quotation. It does not replace engineering approval or a project drawing review. Buyers should confirm the exact model, quantity, destination, schedule and equipment context before making a sourcing decision.

Why MX contactor references are useful in buyer RFQs

High-current DC contactor requests often arrive as short model lists inside a broader power-control bill of materials. A buyer may include contactors, relays, high-voltage fuses and battery disconnect switches in the same message, while only giving a voltage class or a partial family name. That can slow the quotation discussion because contactor type, coil voltage, auxiliary contact requirement and termination style all affect the correct review path.

The MX records help buyers separate sensing and latching needs at the start. MXSB16BE and MXSB16CE are listed as sensing contactor options with 600A - 48Vdc rating lines. MXSL15BE and MXSL15CE are listed as latching contactor options with 350A - 48Vdc rating lines. Keeping those distinctions visible helps a purchasing team avoid treating every MX line as the same DC contactor request.

Key fields to keep visible before quotation

The MXSB16BE and MXSB16CE records share several fields: upright mounting, Epic sealing, internal coil suppression, 8 Pin Deutsch Connector coil termination, no auxiliary contact, non-bidirectional configuration, 910 gram weight and Reach and RoHS compliance. The main ordering difference shown in the records is coil voltage: MXSB16BE lists 12 Vdc and MXSB16CE lists 24 Vdc.

The MXSL15BE and MXSL15CE records are latching contactor references. They also list upright mounting, Epic sealing, 8 Pin Deutsch Connector coil termination, no auxiliary contact, non-bidirectional configuration and Reach and RoHS compliance. Their records show 500 gram weight, no economizer and the same coil voltage split: MXSL15BE lists 12 Vdc, while MXSL15CE lists 24 Vdc.

How buyers can make the inquiry cleaner

A stronger MX series RFQ should include the complete model number rather than only the family name. It should also include target quantity, delivery destination, expected purchase timing and whether the request is for replacement, maintenance stock, pilot production or a new design review. If the project needs auxiliary contacts, bidirectional behavior or a specific coil voltage, those points should be stated clearly.

When a buyer is comparing contactors with DC power relays or protection components, the RFQ should keep each product group on a separate line. That makes it easier to review a 48Vdc contactor request alongside a high-voltage relay, fuse or battery disconnect switch without losing the critical model-level details.

Where these MX options fit in sourcing plans

MX sensing and latching contactor references can be relevant for buyers organizing DC power switching options around 48Vdc equipment. Sensing contactor records may be useful when the project discussion includes current visibility or protected power-control assemblies. Latching contactor records may be useful when the buyer is reviewing maintained-state switching requirements and wants to reduce continuous coil-power assumptions.

Sorint can support RFQ discussions for MX series contactors, high voltage DC contactors, DC power relays, battery disconnect switches and high-voltage fuse products. Buyers can send the exact model references, quantities and application background so the quotation discussion starts with the right product family and fewer repeated clarification rounds.

FAQ

What should I include in an MX series contactor RFQ?

Include the exact model number, quantity, destination country, target delivery window, coil voltage requirement and equipment context. If the request is for replacement, include the existing purchasing record or approved model label.

Are MXSB16BE and MXSB16CE the same contactor?

No. The records are closely related sensing contactor references, but the coil voltage field differs. MXSB16BE lists 12 Vdc, while MXSB16CE lists 24 Vdc.

Can Sorint quote MX latching and sensing contactors together?

Yes. Buyers can include both sensing and latching contactor lines in the same RFQ, provided each line shows the exact model reference, required quantity and application background.
