SOLH MHC2 Series Angular Pivot Pneumatic Gripper Full Product Introduction

Brand: SOLH by Richge Technology 

Product Overview

     SOLH MHC2 series is standard pivot angular 2-jaw pneumatic gripper. Driven by dual pistons pushing rocker mechanism, jaws rotate around bottom pivot point instead of linear parallel travel. Maximum jaw swing angle: 30°. Available bore sizes: 6/10/16/20/25mm. Two operation variants: double acting (D) & single acting normally open (S). Built-in adjustable throttle valves for speed regulation. Compatible with M9BW series magnetic switches for open/closed status feedback. Direct dimensional interchange with imported MHC2

     Complementary to MHZ2 parallel gripper: MHZ2 = jaws linear translation; MHC2 = rotary swing jaws. Ideal for narrow in-depth installation space and outer-side workpiece grabbing applications.

Complete Model Coding Rule

  1. Format: MHC2 - 16 D - □ - M9BW - □

     -- MHC2: Series code, standard pivot angular gripper

     -- 16: Bore size: 6 / 10 / 16 / 20 / 25 mm

     -- Operation Mode

       * D: Double Acting — Air supply clamps, reverse air releases; high clamping torque, mainstream universal type

       * S: Single Acting NO Normally Open — Air supply clamps; spring automatically releases workpiece when air cut

         Note: Standard MHC2 does NOT provide single acting normally closed (NC) variant

     -- Middle segment: Body option (MHCA2 short body / end port variant; blank = standard side port base model)

     -- M9BW: Magnetic switch

        * Blank = No switch (magnetic ring pre-installed, only mounting slot reserved)

        * M9BW / M9BL = universal solid-state magnetic switch for position feedback

     -- Suffix: Quantity of magnetic switches

        * Blank = 2 pcs standard (detect both clamp & release position)

        * S = Only 1 single magnetic switch

  2. Standard Order Example

     MHC2-16D-M9BW：MHC2 standard angular pivot gripper, bore 16, double acting, 2pcs M9BW magnetic switches, standard side port body.

Working Principle & Core Competitive Advantages

  1. Pivot Rocker Swing Mechanism

     Jaws rotate around bottom pivot. Jaw tips expand outward when opening. Perfect for outer-side clamping where parallel grippers risk mechanical interference due to insufficient depth space. Swing range: +30° ~ -10°.

  2. Symmetric Dual Piston Drive

     Generates large clamping torque; both jaws swing synchronously with balanced load. Built-in one-way throttle valves, no extra speed control fittings required to adjust opening/closing velocity.

  3. Low Height Compact Body

     Thin outline, great for miniature robot end effector and cramped cabinet installation.

  4. Oil-Free Operation

     Long service grease pre-filled at factory, compatible with dry filtered compressed air for continuous cycling.

  5. Magnetic Position Detection Ready

     Built-in magnetic ring, cooperate with M9BW switches to transmit jaw status signal to PLC for workpiece presence judgment.

  6. Multi-Directional Mounting Base

     Locating pin holes and tapped mounting holes on bottom surface; horizontal & vertical mounting supported. Extended custom fixture can be fitted onto jaws.

Selection Comparison: MHC2 Angular Gripper VS MHZ2 Parallel Gripper

Step-by-Step Selection Guide

  1. Operation Mode Selection

     -- 24h continuous mass automation, demand maximum clamping torque → D double acting (preferred mainstream)

     -- Hot pressing / stamping stations, auto release to avoid workpiece crushing after power loss → S single acting NO

        MHC2 standard series without NC power-off hold type. If permanent clamping after power cut is required, select MHZ2-C series.

  2. Working Condition Judgment

  ✅ Prioritize MHC2 if:

     -- Limited equipment depth; parallel linear gripper interferes with frame during travel

     -- Side feeding process, grab workpiece from outer circumference

     -- Outer clamping for small plastic housings, bottle caps, tubular parts

     -- Mini robot EOAT requires ultra-thin compact gripper outline

  ❌ Choose MHZ2 instead if:

     -- Workpiece needs centered stable clamping without rotary torque

     -- Long extended custom fixture is required (severe torque attenuation risk)

     -- Ultra-high repeat positioning ±0.01mm is mandatory

     -- Power-off permanent clamping (NC normally closed) required

  3. Signal Detection Option

     -- Fully automatic production line with PLC workpiece identification → Equip M9BW magnetic switches

     -- Simple manual fixture without automatic logic → Basic model without switches

Typical Industrial Application Scenarios

     -- 3C Automation: Outer clamping of plastic housings & connectors, miniature component assembly

     -- Packaging Machinery: Bottle cap picking, lateral transfer of small material boxes

     -- Inspection Tooling: Outer positioning for tubular and cylindrical workpieces

     -- Mini robot end effector for side pick & place in confined space

     -- Injection molding auxiliary equipment: Demolding & picking micro plastic parts

Standard Matched Pneumatic Circuits

  1. Circuit 1: General Double Acting Gripper Circuit

     AFC air service unit → 4V210 5/2 solenoid valve → PU6 tubing → MHC2 angular gripper (M9BW switches wired to PLC input)

  2. Circuit 2: Single Acting Normally Open Safety Circuit (auto release after power loss)

     -- AR pressure regulator → 3V 3/2 solenoid valve → MHC2-XXS single acting NO gripper

Operation & Maintenance Precautions

     -- Install AF series 5μm precision air filter upstream; dust entering pivot joint will cause jamming.

     -- Minimize fixture extension length; longer fixtures lead to severe effective force reduction and risk of workpiece slipping.

     -- Avoid eccentric heavy load; unilateral force accelerates wear of pivot pins.

     -- Adjust jaw speed gradually by built-in throttle; rapid high-speed impact will damage workpieces.

     -- Standard seals are not resistant to strong acid, alkali & organic solvents; fluorine rubber seal customized version for corrosive environments.
