MPL 600

Introduction

MPL 600 Series switches offer pressure or vacuum sensors which combine the features of the MPL 500 Series with snap action switching for higher current capacity, SPDT contact form and switch deadbands (also referred to as mechanical differential or hysteresis). Miniature size and low cost make the MPL 600 Series ideal for OEM applications.

Description

MPL 600 Series switches utilize high-quality miniature snap-action switches. Like the 500 Series all are diaphragm operated. Diaphragm material can be selected for the operating medium, temperature range and other parameters. During the development of a specification, actuation point can be adjusted by the designer. In production, factory setting is required.

MPL 600, 601 and 602 are single setting models. The MPL 604 offers two micro switches, each operated by an independent diaphragm.

Electrical

MPL 600 switches are designed for heavy current loads. Depending on pressure setting, ratings are available from 3A to 25A, and 0.1HP to 1.0HP. For low-current applications, special contacts are available for milliamp loads. link in

Terminals

Three 0.020" x 0.187" male tabs are standard (0.032" x 0.250" available). Special OEM terminals are available.

Actuation Settings

MPL 600 pressure models are available from 1.5 in/H 2 O to 45 psi. Vacuum models are available from 4.0 in/H 2 O to 14 psi. Tolerance is typically +/- 10% of setpoint.

Special Ports & Mounting

MPL 628 adds a molded (or die-cast) 1/8" NPT fitting to the MPL 602 features. MPL 609 adds a 5/32" barbed brass fitting, with a nut and washer, for panel mounting.

Beyond the 600's... The MPL 808

The MPL 808 extends the range of MPL 600-style switches with snap action in an all-metal housing, designed for moderately higher pressures. Actuation may be specified between 10 psi and 250 psi.

Description

The MPL 808 utilizes a sensor body die cast of aluminum-zinc alloy, with a 1/8" NPT fitting. Like the rest of the 600 Series, the MPL 808 is diaphragm operated. Diaphragm material can be selected for the operating medium, temperature range, and other factors. During development of a specification, actuation point can be adjusted by the OEM designer. In production, factory setting is required.

Specifications

  • Body: aluminum-zinc alloy
  • Diaphragm: polyurethane standard, other materials available
  • Snap Switch: UL & CSA listed, wide selection
  • Operating Temperature: -40 to +85C, (-40 to +185F), depending on components. Consult factory.
  • Pressure: 10 psi to 250 psi
  • Burst: 500 psi
  • Form: SPDT
  • Terminals: Three 0.020" x 0.187" male tabs standard. Three 0.032" x 0.250" available. Special OEM terminals available.
  • Dimensions: 2.0 x 2.0 x 1.0 inch
  • Weight: 2 ounces (57 grams)
