These are differences in specifications between Panasonic rhs2 and rhs2b high speed radial lead component insertion machines,
| Item | RHS2 | RHS2B |
| Main body (Handwheel) | Wheel axis provided independently from the tension roller shaft | Wheel axis shared with the tension. |
| XY table (Width adjustment) | Rail width adjusted with belt. | Normal rail width adjustment (without belt). |
| XY table (movable rail) | Plate springs for rail holding. | Simplified guide plate (No plate springs for rail holding). |
| Insertion head (P−axis) | P−axis motor + reduction gear. (Speed redution ratio 1:5) | P−axis motor only (No reduction gear). ( Pulley ratio 1:2). |
| Insertion head (camshaft) | Reverse torque cam and two separate fulcrum shafts. | Reverse torque cam eliminated and fulcrum shaft unified. |
| Insertion head (insertion pusher) | Deflection when insertion pusher pressure is low: 3 mm | Deflection when insertion pusher pressure is low: 5 mm |
| Insertion head (reduction gear) | Reduction gear mounting plate | Simplified reduction gear mounting (No mounting plate) |
| Anvil (cam box) | Cam box and side plate provided separately. | Integrated cam box (No side plate) |
| PC board transfer units (loader/unloader) | Vertical motion by rotary actuator | Vertical motion by air cylinder |
| PC board transfer units (walking beam) | Driven by reversible motor | Actuated by air cylinder |
| PC board transfer units (PCB stopper) | Actuated by air cylinder | Actuated by spring and mechanical unit |
| PC board transfer units (unloader pusher) | High speed pusher motion Air switching | Normal unloading (No high speed motion or air switching) |
| Parts processing unit (cutter) | Fixed from outside of V-cut unit | Simplified mechanism (Structure inside V-cut unit) |
| Parts processing unit (reduction gear) | Reduction gear mounting plate | Simplified reduction gear mounting (No mounting plate) |
| Feeder carriage (Parts cassettes) | Waste suction function | Waste suction function eliminated |
| Feeder carriage (Pallet rail) | Pallet rail guide | Pallet rail guide eliminated at two points (parts processing – head, head-Z) |
| Pneumatic unit (exhaust cleaner) | Concentrated exhaust (exhaust cleaner) | Silencer exhaust(exhaust cleaner eliminated) |
| Control unit | Tact time 4-step changeover 0.2s, 0.25s, 0.36s, 0.45s | Tact time 5-step changeover 0.17s , 0.2s, 0.25s, 0.36s, 0.45s |
