HEAVY WEIGHTED PRESSURE PLATE
An iron pressure plate that outputs signal strength based on the number of entities on it. Every 10 entities adds 1 signal strength, up to 15. Used for entity counting.

Overview: what the Heavy Weighted Pressure Plate is and does
An iron pressure plate that outputs signal strength based on the number of entities on it. Every 10 entities adds 1 signal strength, up to 15. Used for entity counting.
As a power source it sits at the start of a circuit, generating the signal that everything downstream reacts to. It is an analog counting plate, reading crowd density rather than acting as a simple on/off switch.
The Heavy Weighted Pressure Plate was added to Minecraft in 1.5 and everything described here reflects its behaviour in Java Edition 1.21.
How it works: the redstone mechanics
On the input side, entities standing on it. On the output side, signal strength = ceil(entity count / 10), max 15.
Its output is ceil(entities / 10) capped at 15, so it takes 10 entities to reach signal 1 and 150 entities to max out at 15. The iron texture distinguishes it from the gold light-weighted plate, which counts one entity per signal.
Timing-wise, factor in 5 redstone ticks after all entities removed when you wire it into a sequenced circuit.
It can output a maximum signal strength of 15, which travels 15 blocks through bare redstone dust before fading to nothing.
It operates in the following modes: analog signal based on entity count.
How to set it up
- 1Craft the Heavy Weighted Pressure Plate: 2 Iron Ingots → 1 Heavy Weighted Pressure Plate.
- 2Decide where the signal needs to start or land, then place the Heavy Weighted Pressure Plate against a solid surface so it can feed the rest of your circuit.
- 3Run redstone dust away from it toward the component you want to control, remembering the signal will fall by 1 per block.
- 4Test in a creative-mode plot first: trigger the input and confirm the Heavy Weighted Pressure Plate behaves exactly as the timing above predicts before committing it to a survival build.
Uses & applications
- ▸Entity counting
- ▸Mob farm density detection
- ▸Analog signal generation
- ▸Crowd-based mechanisms
Tips & common mistakes
- !Confusing with light weighted plate (gold)
- !Requires many entities for high signal
- !With so few entities per step it is poorly suited to fine counting — use the gold light-weighted plate when you need one-entity resolution.
Heavy Weighted Pressure Plate FAQ
What is the Heavy Weighted Pressure Plate used for in Minecraft redstone?
The Heavy Weighted Pressure Plate is most often used for entity counting, mob farm density detection, analog signal generation, and crowd-based mechanisms. As a power source it sits at the start of a circuit, generating the signal that everything downstream reacts to.
What signal strength does the Heavy Weighted Pressure Plate output?
Signal strength = ceil(entity count / 10), max 15. Its maximum signal strength is 15.
How do you craft the Heavy Weighted Pressure Plate?
2 Iron Ingots → 1 Heavy Weighted Pressure Plate. It was introduced in 1.5.
Does the Heavy Weighted Pressure Plate add any delay to a circuit?
Yes — 5 redstone ticks after all entities removed. Account for that timing when chaining it with other components, especially in clocks and fast doors.
How many mobs does a heavy weighted pressure plate need for a full signal?
The heavy weighted pressure plate outputs ceil(entity count / 10), capped at 15. It therefore needs 150 entities standing on it to reach the maximum signal strength of 15. Ten entities give signal 1, twenty give 2, and so on.
